Megachannel Device for Advanced Colonoscopy
A Novel Endoscopic Device (Megachannel™) For Repeated Right Colonic Access During Colonoscopy

Megachannel is a newly developed colonic access system allowing rapid and multiple passes of the colonoscope to the right colon.

The investigators want to conduct a multinational study to evaluate the safety and clinical feasibility of placing a 100 cm Megachannel prototype in the right colon.

Patients scheduled for colonoscopy with suspected right colonic polypoid lesions will be included. The prototype will loaded onto a 160 cm lower GI endoscope and introduced via colonoscopic guidance. Time to cecum, total investigation time, clinical feasibility and complications will be recorded.
Phase 2
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
  • Multiple Polyps Right Colon
  • Large Polyp Right Colon
  • Suspected Polyp Right Colon
Device: Colonoscopy with Megachannel™ device loaded
Before colonoscopy, megachannel is loaded on the endoscope, during colonoscopy megachannel will be inserted into the patient via the endoscope placed in the colon
Other Name: Megachannel(TM), produced by Minos Medical, Irvine, CA
Experimental: Megachannel Application
Colonoscopy with loaded Megachannel is performed
Intervention: Device: Colonoscopy with Megachannel™ device loaded
