Endoscopic submucosal dissection hood

Abstract

The present disclosure relates to the field of endoscopy. In particular, the present disclosure relates to systems and methods suitable for resecting or dissecting large areas of mucosal or submucosaltissue. The system may apply tension to and continuously manipulate mucosal tissue such that large lesions may be resected or dissected by a cutting element disposed at the distal end of an endoscope.

Description

[0001] priority [0002] This application claims priority under 35 U.S.C. §119 to U.S. Provisional Patent Application No. 62 / 245,472, filed October 23, 2015, which is hereby incorporated by reference in its entirety for all purposes. technical field [0003] The present disclosure relates to the field of endoscopy. In particular, the present disclosure relates to systems and methods for endoscopic submucosal dissection (ESD) and / or endoscopic mucosal resection (EMR). More specifically, the present disclosure relates to an endoscopic housing that provides enhanced visualization of the working area within which tissue engaging elements and tissue cutting elements operate to dissect or resect mucosal and submucosal lesions. Background technique [0004] Physicians are increasingly willing to perform interventional and therapeutic endoscopic procedures including, for example, full-thickness removal of large tissue lesions such as cancer, submucosal tunneling in the gastrointes...

AI Technical Summary

Problems solved by technology

The fully circumferential design of currently available endoscope hoods tends to hinder visualization of target tissue and provides little workspace making it difficult for multiple tools to be manipulated simultaneously

While dual-channel endoscopes may be available in some medical institutions, the separate articulating tools within each channel are often ergonomically difficult to control, especially by a single physician
