Patent number: 10245026Abstract: The present invention relates to devices, and methods for using the devices, to create and secure a tissue fold during an endoluminal medical procedure. The devices and methods may be used for folding and securing, for example, a fundus wall onto an esophagus wall or esophageal tissue in the region of the lower esophageal sphincter (LES) to reduce the diameter of the esophagus opening in that region. One aspect of the invention includes forming the tissue fold by closing a grasping arm that is pivotably connected to an overtube that has been positioned at the juncture of the fundus wall and esophagus wall. A further aspect of the invention includes tissue clips configured to be inserted and positioned through an endoluminal device.Type: GrantFiled: August 31, 2015Date of Patent: April 2, 2019Assignee: Boston Scientific Scimed, Inc.Inventors: Marc O. Schurr, Kurt Geitz, Robert Sakal, Gerhard F. Buess, Daniel Kalanovic

Patent number: 8663241Abstract: A full-thickness resection system is disclosed. In an embodiment for the resection system, the system may include a flexible shaft, a flexible guide member disposed within the flexible shaft, a stapling mechanism disposed around the flexible guide member, and a grasper. The stapling mechanism has an elongated portion that is at least partially disposed within the flexible shaft. The stapling mechanism includes a stapling arm and an anvil arm. The stapling arm has a longitudinal axis and includes a stapling head having a longitudinal axis. The anvil includes an anvil head. The stapling arm and anvil arm extend from the elongated portion of the stapling mechanism and are moveable with respect to each other between a tissue receiving position and a stapling position. The grasper extends through the flexible shaft and is adapted to grasp a portion of a tissue that is to be excised from an organ in the patient's body.Type: GrantFiled: January 17, 2003Date of Patent: March 4, 2014Assignee: Boston Scientific Scimed, Inc.Inventors: Ronald D. Adams, Roy H. Sullivan, Gerhard F. Buess, Marc O. Schurr

Patent number: 8006889Abstract: 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: January 19, 2011Date of Patent: August 30, 2011Assignee: Boston Scientific Scimed, Inc.Inventors: Ronald D. Adams, Roy H. Sullivan, III, Lauren O. Main, Peter K. Kratsch, George A. Nunez, Jurgen A. Kortenbach, Matthew S. Solar, Gerhard F. Buess, Marc O. Schurr

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
