Mauna Kea Technologies is a global medical device company focused on leading innovation in endomicroscopy, the field of microscopic imaging during endoscopy procedures. The company researches, develops and markets tools to visualize, detect and rule out abnormalities including malignant and pre-malignant tumors or lesions in the gastrointestinal and pulmonary tracts.

The company’s flagship product, Cellvizio, a probe-based Confocal Laser Endomicroscopy (pCLE) system, provides physicians and researchers with real-time access to histological information during standard endoscopy procedures through high-resolution cellular imaging of internal tissues.

Cellvizio went public in July 2011 and trades on the NYSE Euronext exchange.

The Cellvizio system can be used during any endoscopy procedure, offering a cellular-level view of internal tissue. Large, international, multi-center clinical trials have demonstrated Cellvizio's ability to help physicians to more accurately detect disease in real time, confirm the absence of disease and make immediate treatment decisions.

The Cellvizio system includes miniaturized optics, optical fiber bundles, high-speed scanning and advanced image processing components. The embedded real-time image processing software, combined with a high-speed Laser Scanning Unit (LSU), allows the Cellvizo system to produce sharp images at 12 frames per second.

Mauna Kea Technologies developed a series of Cellvizio confocal miniprobes designed specifically for various endoscopy procedures. The resolution of Cellvizio images depends on the type of miniprobe used.

The Cellvizio system has received 510(k) clearance from the U.S. Food and Drug Administration (FDA) and the European CE-Mark for use in the GI and pulmonary tracts.

Over 300 physicians and researchers at more than 200 international hospitals and research centers use the Cellvizio system. Over 10,000 patients have undergone endoscopy procedures where Cellvizio was used.

Clinical Applications[edit]

Through multiple clinical trials, the use of pCLE has been shown to be beneficial to the detection and/or characterization of pre-cancerous lesions.

Barrett’s Esophagus[edit]

Cellvizio provides a direct method to visualize the microstructure of the esophagus and differentiate normal versus abnormal Barrett’s Esophagus (BE) tissue in real-time which may improve targeted sampling, provide earlier disease detection and help patient management.[2] Physicians have also used Cellvizio imaging in conjunction with other clinically relevant parameters during BE treatment procedures to guide resection or ablation, to evaluate margins for residual malignancy and to visually monitor the patient’s condition during follow-up endoscopy procedures.[3] In many cases, unnecessary procedures may be avoided which may impact on overall costs, such as endoscopy suite time and pathology testing.

Colorectal Neoplasia[edit]

During standard colonoscopy procedures, physicians remove all polyps and send them to a pathologist for analysis. pCLE with Cellvizio can magnify a polyp by a factor of 1,000 to help a physician detect cellular-level features that differentiate cancerous from benign colorectal polyps during the colonoscopy procedure in real time. With the additional information provided by Cellvizio, the physician can use his/her medical judgment to either leave the polyp or remove it and send it for pathological analysis or just discard it.[4]

Physicians also use Cellvizio during follow-up colonoscopies to re-examine polyp resection sites to determine if re-treatment is necessary.[5]

Mauna Kea Technologies hopes to expand Cellvizio’s use in:

  • Urology
  • Surgery
  • Solid tumors

Pre-Clinical Research[edit]

Mauna Kea Technologies also developed the Cellvizio LAB system for use in pre-clinical research laboratories.

The system’s ultra-thin, highly flexible fibered microprobes come in a variety of sizes and tip shapes that are designed to facilitate imaging of different areas of a living animal. The Cellvizo LAB laser scanning unit (LSU) comes in three models, functioning at either 488, 660 nm or combined (Cellvizio Dual Band), which allows it to function with a wide array of standard dyes or transgenic animals. The system’s ImageCell software performs the on-the-fly image processing that provides users with high-quality, high-definition video sequences in real-time.

Research applications include deep brain imaging, angiogenesis, peripheral nervous system visualization, GI Cancer research, stem cells and pancreatic cancer imaging.
