NPOV[edit]

This article and related articles were written by Satinder Mullick, the father of Tarun Mullick, who is claimed to be an inventor of capsule endoscopy, presenting a conflict of interest. Also, I did a google search and found that Mr. Mullick has a history of promoting his son by posting information about him under false names. All the posts have the same unique writing and punctuation style that is on display in this article. Jehfes 05:36, 21 August 2007 (UTC)


These articles have been written by 3 authors with information added to improve the complete coverage for millions of Wiki users who are researchers,users,investors around the world.The Ingestible Camera Capsule has many uses-Dr.Oz used it on Oprah's show to study DIETS scientifically for stressed taxi drivers and truck drivers with constipation.The ingestible Capsule was used by astronauts and there are several application patents. Wikipedia can provide detailed information in one place.

If someone wants to delete--then you are basically deleting important information. Wireless Capsule Endoscopy is same as Capsule Endoscopy--Delete Capsule Endoscopy but not wireless Capsule Endoscopy written by a good author unknown to me.SO KEEP WIRELESS CAPSULE ENDOSCOPY.

Miniature Ingestible Capsule is the oldest name in use for many applications including Endoscopy but not limited to that alone.DO NOT DELETE THAT.

Also,please write your true names--WHY HIDE behind--You may be ignorant about new developments--but others want to know what is going on.Olympus and Given are spending 20 million$ in legal expenses.Like Blackberry,this is the best technology in Medical field. —Preceding unsigned comment added by SatinderMullick (talkcontribs) 15:27, 6 October 2007 (UTC)


Capsule endoscopy takes a very narrow view of what is possible.Olympus EndoCapsule is soon going to take a lead and other developments are going to save thousands of unnecessary deaths from Colon Cancer.This article after editing is worthless compared to other articles by others available thru Google search.

Someone is trying to feed in False information in this article.Whether it is ignorance or hidden agenda is unknown as the true identity is not revealed.Example--Statement that Iddan invented the first Capsule is under US Court review--and US Patent office rejected 4 KEY CLAIMS out of 17 in 2006 based on Olympus reexamination request in 2003.There are basically three US patents 7039453( owned by Microgizzmos) and 69392929 Owned by Olympus) besides Iddan's patent which is now owned by Given Imaging.The Patent case is now in Eastern Pennsylvania Court and final verdict will take 2 years or more.So Wikipedia will be misleading the readers by presenting False or Incomplete information. —Preceding unsigned comment added by SatinderMullick (talkcontribs) 14:15, 7 October 2007 (UTC)

Which is why I added a citation tag. Did you not notice that? I will review it further later. - Cyborg Ninja 15:26, 8 October 2007 (UTC)

Cyborg Ninja--It seems someone keeps pushing Iddan name.The reality is that his US Patent has been partially changed with Claims 1,2,3 and 4 for Capsule Endoscopy Camera rejected on April,2006 by US Patent office based on Olympus appeal.At that time,USPTO issued "System Patent" to Tarun Mullick,Sudhir Dutta et.el(patent# 7039453)

  1. The "REAL INVENTOR" case will be decided in Courts in 2/3 years.
  2. Currently--This Capsule has shown superiority in "SMALL BOWEL"viewing.
  3. Soon,Colon Cancer Screening will help millions using this non invasive Capsule.
  4. Sayaka URL was added by me--Sayaka is working on external battery source--but real advancements are in making Capsule do what current Endoscopes allow the doctors to do "WIRELESSLY"--See the problem and surgically remove the problem. Stanford Univ. and Microgizzmos have patents pending for this great advancement.Research papers and Patent documents are in public domain.

Cyborg--YOU ARE A GREAT WRITER--Help write a great article on Capsule Endoscopy--with ACCURATE INFORMATION with NO BIAS.I can provide Accurate sources of information to be included(of Course VERIFY before including)

By the way,You should see Dr.Robert Baldassano of Children's Hospital of Philadelphia--He himself suffers from Crohn's and was written up in the US News & World report of Sept.3,2007. For your information,I was a top Executive--Our article on Forecasting in Harvard Business Review in July 1971 was the best seller translated in 5 languages and sold over 5 million copies.

I did my doctorate from Johns Hopkins Univ. in 1965--where the motto is; "SEEK TRUTH".I have supported many causes for Cancer,Crohn's disease etc. Satinder Mullick —Preceding unsigned comment added by SatinderMullick (talkcontribs) 20:30, 8 October 2007 (UTC)

I've gotten rid of the Iddan reference. I do see your reasoning here. I myself had copied the reference about Iddan from an older version of one of the other articles. It didn't have a citation at the time, so I added a citation tag. But since I feel like you're probably right here -- it's likely multiple researchers developed the technology around the same time, when fiber optics technology came into prominence.
Please see your Talk Page. There's a lot you need to learn about Wikipedia editing from there. Computers can be unpredictable and hard to work with sometimes. Wikipedia has a special "language" that it uses to format your words. This is what is causing a lot of trouble with your additions to the articles. It is hard to read. By the way, I did see your comments about Crohn's disease on my User Page and I appreciate them. I moved them to my Talk Page. - Cyborg Ninja 21:48, 8 October 2007 (UTC)

Cyborg Ninja--Thanks.There are many articles about this subject.The usefulness of Capsule is cited in many articles.Capsule Endoscopy is helping detect Bleeding source in Small Bowel where Endoscope can't reach properly.So for today's state of art,there is adequate coverage. However,the need for further advancements so that Capsule can detect and correct problems like thru Colonoscopes where doctors can remove Polyps which later can become Cancerous ,is also underway.If that becomes a reality in 3/5 years,then many hundreds of thousands of lives will be saved.

Wikipedia is a source where Truthful information needs to be available.I have not added my inputs under fictious name.If it is verifiable information,then it should be available to all.

Wish you all the best.Satinder Mullick

Low importance?[edit]

I definitely disagree with consensus that the subject is of "low importance" to the field of Medicine. I may not share other users' enthusiasm for capsule endoscopy, but even I recognize how important it is to gastroenterology and imaging of the body. Just ranting. - Cyborg Ninja 06:58, 20 October 2007 (UTC)

It is certainly an important diagnostic tool. However importance is judged by the probability of need of an average user to look up in an encyclopaedia. Pls see project assessment page--Countincr ( t@lk ) 09:57, 20 October 2007 (UTC)
Trust me, I'm already aware of that. You don't need to go into semantics, though I disagree about the "probability of need of an average user to look up in an encyclopedia." It was categorized in the Medical project, not for the average user. But anyway, like I said, it was just a rant. - Cyborg Ninja 02:51, 21 October 2007 (UTC)

There are many who suffer from Crohn's disease or have Colon Cancer.Wikipedia is a source that should encourage people to LEARN ABOUT CAPSULE ENDOSCOPY that is revolutionizing detection of problems.This week--Oct.15,2007--Wake Forest Univ. researcher reported that they found Crohn's disease that wa undiagnosed for upto 15 years in their study.This study was presented at Amer.College of Gastroenterology meeting in Philadelphia. www.physorg.com/news111757757.html PEOPLE MUST BE EDUCATED to ask their Doctors for this NEW TECHNOLOGY.US is ahead--Japan has just started. —Preceding unsigned comment added by SatinderMullick (talkcontribs) 17:48, 20 October 2007 (UTC)

I added a reference for it to the article. Thanks for the info. - Cyborg Ninja 15:17, 21 October 2007 (UTC)

Inventor or Developer[edit]

A recent addition was made to the article about a supposed early developer of the capsule endoscope. It needed a reference, so I reverted to an earlier version. Normally, I'd add a citation tag but the editor himself made various claims about capsule endoscopy inventors and how he himself had a problem with mentions of such people without references. I thought that was odd. If there is a reference, I'd be happy to add it, but from my research there seems to be conflicts among many as to who first created it. - Cyborg Ninja 07:12, 31 October 2007 (UTC)

It seems that someone related to Israel keeps adding their favorite inventor.There are three groups claiming to be inventors:
  • Iddan et el(patent bought by Given Imaging)-an Israeli company-their claims 1,2,3 and 11 out of 17 relating to Capsule System have been rejected in 2006 after 3 years reexamination at Olympus corp. request.
  • Mullick ,Dutta et el. of Baltimore,Md.USA developed this Capsule in 1989 and were granted a patent by US patent office.
  • Olympus Corp. of Japan also received a patent which they filed two years after Mullick et.el

SO EITHER we do not name any one--or add everyone's name until US Courts decide in 3/4 years whose patent is key and who is the first inventor. Satinder Mullick —Preceding unsigned comment added by SatinderMullick (talkcontribs) 16:10, 31 October 2007 (UTC)

I think it's best to name everyone. It's a risk for us to name one group as being absolutely the inventor when it's currently being disputed, because of the popularity of Wikipedia and the possibility other people will use it as their only authority when writing about capsule endoscopy. I need references, though. - Cyborg Ninja 00:44, 4 November 2007 (UTC)

User:Cyborg Ninja

      Three inventors fighting for their patents.Here are the URL that gives brief description.Only PLEASE add a note that Claims 1,2,3 and 11 of US Patent# 5604531 were rejected in April 2006 by USPTO based on Olympus Corp. appeal for reexamination--These Claims refer to the word " System".The  Press release on this was removed by Given Imaging after a month.IP Factor of Israel has this news on the internet and Given Imaging SEC filings mentions it in a paragraph ,but you have to read lot of unnecessary material.

This article could be more helpful[edit]

I will be swallowing one of these in a few weeks. The doctor mentioned that there is a small risk of the capsule getting stuck, and in that case, they have to "open me up." The introduction is irrelevant to those seeking timely medical information, and there is no mention of the procedure (i.e. laxative prep is required) and of the possible complications. Could we centralize and expand the medical content of this article, and compartmentalize the disputes over patents to a separate section? Thanks, --71.76.39.125 (talk) 01:35, 29 January 2008 (UTC)

Still learning to wiki, but I am a GI nurse in the US with a current Given imaging system in my lab. Whether or not you need a laxative prep before the test is up to your Doctor and will be based partly on what your presenting problem is. If you were coming to my lab and your MD said do whatever the lab at the hospital asks you to do, here is a synopsis of what I would send you in the mail:

You mave solid food for lunch the day before the test. After lunch clear liquids only until midnight. Starting one minute after midnight now on the day of the test I want you to have nothing at all by mouth except for the pills you think are important enough to call and ask about.

Many labs will ask you to have no clear liquids with red in them. I am currently asking patients to not have anything colored red, orange or purple. Any of those dyes "can" look like blood in the small bowel. Medically a clear liquid can be any color, as long as it is not cloudy or opaque. Apple juice is a clear liquid. Orange juice is not a clear liquid. Chicken broth is a clear liquid. Cream of Mushroom soup is not a clear liquid.

When you arrive in my lab we will talk about the risks associated with the test. The pill might get stuck. If it does get stuck and it stays stuck, someone will need to get it out. A quick X-ray or two would be enough to show the surgeon where the thing is so it could be removed laparoscopically. I am sure the is published data on the frequency of capsules getting stuck. I do not have a reference in my windows clipboard. I have been running these tests out of my lab since 2002. I have sent two people to the ER for abdominal films. 1 of those went to surgery. Whatever the published rate is, it is going to be pretty low.

Besides bowel obstruction caused by a stuck capsule, there is a risk the study will be incomplete. The system I am curently using holds 8 hours of data in the recorder. Ordinarily the capsule will spend about ten seconds in the esophagus, perhaps and hour in the stomach, four hours transiting the small bowel, and then be "somehwere in the colon" at the end of the recording. I can think of two patients who passed the capsule all the way through their gut and flushed the video capsule in about 4 hours flat.

Also, this procedure is very rarely done on bed ridden or activity intolerant patients. If you are very ill or very weak, unable to walk; then likely the camera will just sit in your stomach all day and never enter your small bowel. In some cases your doctor may want to place the camera capsule directly in your small bowel using an endoscope and a grasping tool that reaches through the scope to grasp the camera capsule. This is very unusual; generally if you aren't active enough to walk the capsule isn't going to move along down the tube very well.

Still just at my lab: 2 hours after you swallow the camera you can have some clear liquids. Four hours after you swallow the capsule you can have a snack and some more clear liquid. A snack is less food than "lunch" by about half.

At my lab patient medicines are case by case and only an idiot would dispense medical advice on the internet. If you are going to have a capsule and want ot know about taking which of your pills call your doctor or the nurse at the lab who will be running your test.

The transmitter in the capsule is very low power. It is OK to sit in front of your laptop while talking on your cellphone and surfing the internet through your ireless connection. Direct sunlight through sheer clothing will degrade the image quality of the study. Spending the afternoon at the foot of a radio or television tower will degrade the quality of the recorded images. If you see someone else wearing the same recorder as yu are wearing today, please do not stand too close to one another. 20 feet or so is nothign to wirry about.

Finally, you must be sure the capsule has passed before you have an MRI. If there is any doubt the people at the MRI lab should be able to take a quick look with fluoroscopy (a low powered Xray) to make sure the Capsule is no longer in your body.

Some of the problems occur partly because these things aren't designed very well. If these things are designed to display the small intestine and they are known to sit in the stomach for an hour before entering the small intestine and battery life is an issue and you don't need a thousand pictures of the stomach why doesn't it take and transmit pictures far more infrequently for that first hour and then begin to increase the picture taking rate later? Put it in like a sleep or a dormant state, why should it take and transmit 1 picture every ten (or whatever) seconds when in the stomach when you don't need that. Have it take like 10 or 20 pictures during the entire hour in the stomach so that you can get a general idea of how the stomach looks and, after like 45 minutes to an hour have it start waking up from sleep mode or whatever and start taking more regular pictures. That way it can save battery life and get a more complete view of the digestive track. Maybe even an outside trigger can be sent to the camera to tell it when to 'wake up' and begin taking more pictures when it is determined that the camera has entered the small intestine (then again, such a thing would require a receiver on the pill which could take more space). Or, maybe have two or three different cameras, one with a one hour delay, one with a two hour delay, and one with a three hour delay before being woken up. The one chosen may depend on the specific characteristics of your patient. If they are old and their digestive system is slow for whatever reason, choose one with a larger delay. Finally, different cameras can also take pictures at different rates about the time when they do reach the small intestine. A camera moving fast through the intestines would probably need to take pictures more frequently while one moving slowly would not need to take pictures nearly as frequently. Perhaps the delay and small intestine picture taking rate can be preset in the software ahead of time. Or have these ideas already been implemented? If so this is something that should be mentioned by the Wikipedia article. BTW, none of these ideas are patentable since big corporations enjoy patenting the most obvious things. — Preceding unsigned comment added by 2602:306:36D9:9F0:D8E2:2077:8B83:2D46 (talk) 15:25, 6 April 2013 (UTC)

Ideas for improvement[edit]

I just spent some time re-writing parts of the article. It could still use quite a bit of work. In particular:

1) Picture of GI tract showing where colo and EGD can see and where they can't 2) Picture from a capsule endoscope 3) Mention of double or single balloon enteroscopy 4) mention of complications 5) Mention of what patients need to do before swallowing the capsule and how it is retrieved.

I'll try to find some time to work on this.

Wawot1 (talk) 17:32, 25 March 2010 (UTC)

"a report" reads weird and is ambiguous[edit]

> There has been a report of retention of the capsule for almost 5 years.

Does that mean "there has only been one report"?

First hand testimony[edit]

I am Eric Fossum and I am the primary inventor of the CMOS image sensor. In the second half of the 1990's, after founding Photobit Corp to commercialize the technology, we were approached by Given Imaging to help them develop the capsule endoscopy. The ultra low power of the CMOS image sensor camera-on-a-chip allowed, for the first time, the possibility of practical capsule endoscopy. We designed a custom CMOS image sensor according to specifications worked out between Given and Photobit. Around 2000, we went into limited production of sensors for Given, and ramped up in 2001. There is no doubt who invented this technology - it was a couple of former guided missile engineers in Israel with a big idea for a little medical camera. Their capsule endoscopy received much press, including being featured on the national nightly news (ABC, I think). If one compares the priority dates of the patents in question, the Iddan patent was first filed in early 1994. The other patents were filed much later. There is not much of a public paper trail other than USPTO applications due to the confidential nature of high tech development. But I am happy to swear to this story in open court. There is a lot of money at stake with this technology, and jury trials are more or less random in outcome when it comes to technology, and USPTO subsequent rejection of claims can stem from a number of reasons, some are just legal procedural issues, not inventive issues. Credit should be given, at least, to Iddan and Given Imaging for first inventing and then first bringing this technology to market including FDA and insurance reimbursement approval. Not giving them credit because of Wiki trolls is just morally wrong. Other subsequent inventions and improvements are also certainly worth noting. -ERF, 2011 Inductee, National Inventors Hall of Fame — Preceding unsigned comment added by 65.175.195.210 (talk) 16:48, 15 August 2014 (UTC)

For better or for worse, Wikipedia reports what independent reliable sources say about a subject. Unfortunately, your comments here are not helpful in that regard as they are not verifiable. - SummerPhD (talk) 17:57, 15 August 2014 (UTC)
The priority dates in the USPTO database ought to be considered reliable and the 3 inventions, sorted by Priority Date could be listed in the article. The rest of the commentary can stay here on the talk page. Iddan et al patent priority date is Jan 17 1994 (US US 5,604,531 A) Mullick et al patent priority date is Feb 8, 2000 - six years later (US 7,039,453) and then Mizuno patent priority date is June 20, 2001. A description of the Given Imaging (Iddan et al inventor)technology was published in IEEE Spectrum, July 2000, page 75, "A Candid Camera for the Gut" by S.K. Moore. Personally, I would not even include the other two later patents since they were years later! -ERF — Preceding unsigned comment added by 65.175.195.210 (talk) 17:32, 17 August 2014 (UTC)
The USPTO is a primary source. Unless the information is discussed in independent reliable sources, Wikipedia generally does not include the information. Adding this would be similar to adding to a biography that the person wears corrective lenses based on drivers license info; it might be true, but it is not encyclopedic. If independent reliable sources stated that the technology was given by E.T. to Tesla, that's what we would report. If independent reliable sources don't discuss who invented liquid soap (and why), neither do we. - SummerPhD (talk) 19:46, 17 August 2014 (UTC)
