DEVICES AND METHODS FOR ANCHORING AN ENDOLUMINAL SLEEVE IN THE GI TRACT

摘要

An endoluminal sleeve device (1) for internally lining a section of the GI tract comprises a sleeve (2) configured for deployment inside a duodenum, the sleeve (2) having walls of a flexible material defining a sleeve lumen (3), a proximal end (4) defining a proximal lumen opening (5), and a distal end (6) defining a distal lumen opening (7), the proximal sleeve end (4) forming an anchoring component (8) extending along a circumference of the sleeve, the anchoring component (8) having a collapsed slender transport configuration and a bulky annular deployed configuration having a size that cannot fit through a human pylorus, and a plurality of auxiliary fixation tabs (9) extending from the anchoring component (8).
