Patent number: 8715270Abstract: Described herein are multi-part instrument systems and methods of use. The instrument can include an inner and outer body member where the inner body member is adapted to dock with the outer body member. When docked, driving the outer body member via a manipulation section can control the inner body. In use, an inner body member can be removed and replaced by a different inner body member to change the tool end effector. Alternatively, driving a manipulation section of the inner body member can control the outer body member. The outer body member can be disposable while the inner body member is reusable.Type: GrantFiled: November 28, 2007Date of Patent: May 6, 2014Assignee: Boston Scientific Scimed, Inc.Inventors: Barry Weitzner, Paul J.

Publication number: 20120165955Abstract: A porous weave of bioabsorbable filaments having an open mesh configuration is formed into an oblate shape having dimensions greater than the esophageal opening and gastric outlet of a stomach. The resulting prosthesis is deployed in the stomach and is of a size to be retained in the proximate portion thereof for exerting pressure on the upper fundus. The prosthesis limits the amount of food that may be held within the stomach, and exerts pressure on the fundus to create a sensation of being full, resulting in weight loss.Type: ApplicationFiled: February 29, 2012Publication date: June 28, 2012Inventor: Kurt GEITZ
