Abstract

A system including surgical compression clips is described and used for endoscopic full thickness resection. Similarly, methods for endoscopic full thickness resection using the described system are also discussed. Surgical compression clips using shape-memory elements are discussed. These clips are advanceable to the site of suspect tissue to be resected through a lumen of a multi-lumen sleeve encasing an endoscope. At the site of the tissue, the compression clip is opened and operated to circumscribe the suspect tissue. Grasper assemblies, advanceable through an endoscope, are also described. These latter grasp and bring the suspect tissue to the open clip. The clip is then closed and the tissue resected. The clip effects necrosis and healing at the resected site.
