Patent number: 7896215Abstract: Described is a full-thickness resection system which includes a control unit coupled to a proximal end of a flexible endoscope. The control unit remains outside of a body when the stapling head is in an operative position within a body lumen. The control unit includes (i) an anvil actuator coupled to an anvil in the stapling head, actuation of the anvil actuator moves the anvil axially relative to a stapling mechanism in the stapling head to compress a folded full-thickness portion of lumenal tissue between the anvil and the stapling mechanism. In addition, the control unit includes (ii) a stapler actuator coupled to the stapling mechanism in the stapling head, actuation of the stapler actuator causing the stapling mechanism to drive staples through the folded lumenal tissue against the anvil.Type: GrantFiled: June 11, 2009Date of Patent: March 1, 2011Assignee: Boston Scientific Scimed, Inc.Inventors: Ronald D. Adams, Roy H. Sullivan, III, George A. Nunez, Lauren O. Main, Peter K. Kratsch, Jurgen A. Kortenbach, Matthew Solar, Gerhard F. Buess, Marc O. Schurr

Patent number: 7059331Abstract: A full-thickness resection system comprises a flexible endoscope and a stapling mechanism, wherein the endoscope is slidably received through at least a portion of the stapling mechanism. The stapling mechanism comprises an anvil and a stapling head mounted to the anvil so that the anvil and the stapling head are moveable with respect to one another between a tissue receiving position and a stapling position and wherein a gap formed between the stapling head and the anvil is larger in the tissue receiving position than it is in the stapling position. A position adjusting mechanism is provided for moving the anvil and the stapling head between the tissue receiving and stapling positions and a staple firing mechanism sequentially fires a plurality of staples from the stapling head across the gap against the anvil and through any tissue received in the gap and a knife cuts a portion of tissue received within the gap.Type: GrantFiled: September 19, 2002Date of Patent: June 13, 2006Assignee: Boston Scientific Scimed, Inc.Inventors: Ronald D.
