A Prospective Investigation of the ColubrisMX ELS System

This study is a prospective, single-arm, open-label, multi-center, feasibility study to evaluate the safety and efficacy of the ColubrisMX ELS System in patients undergoing transanal endoluminal procedures, specifically colorectal Endoscopic Submucosal Dissection.

Endoscopic resection of small polyps is performed routinely through conventional outpatient colonoscopy. Larger polyps or incipient tumors can be excised with endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD). These minimally invasive procedures have been shown to be viable alternatives to conventional surgical resections with less risk of complications, shorter hospital stay and lower costs. Both flexible endoscopic and open/laparoscopic surgical approaches have procedural limitations that can have considerable impact on patient care. Traditional endoscopic tools have technical inadequacies that may inhibit the physician's ability to complete more complex tasks consistent with a surgical technique. Conversely, a traditional open or laparoscopic surgical approach involves increased risk of complications (such as surgical site infection), increased pain and blood loss, longer recovery, and surgical scars. The objective of this clinical study is to assess the safety and efficacy of the ColubrisMX Endoluminal Surgical (ELS) System, a new robotic technology designed to assist the physician with precision, flexibility, and control during endoluminal removal of colorectal lesions.
