Patent number: 9173760Abstract: Several gastrointestinal surgery procedures are effective as treatments for metabolic disorders such as obesity and diabetes. Minimally invasive procedures including intra-luminal gastrointestinal implants have been proposed to mimic the anatomical, physiological and metabolic changes achieved by these procedures. Many of these designs include long sleeve like elements that prevent contact of food with the walls of the small intestine. It is desirable to have simple delivery systems that can place these implants under endoscopic guidance. However, in order to anchor these sleeve elements safely and reliably, the inventors have previously disclosed anchoring means that anchor the sleeves at the junctions of the stomach and the intestine or the stomach and esophagus.Type: GrantFiled: September 30, 2012Date of Patent: November 3, 2015Assignee: MetaModix, Inc.Inventors: Kedar R. Belhe, Paul J. Thompson, Alexander D. Grafov, Werner Schwarz

Patent number: 9173677Abstract: An access port for performing surgery transvaginally is provided. The access port includes an elongated flexible member having proximal and distal ends and a central portion therebetween, and a retention mechanism formed on the distal end of the elongated member. The retention mechanism includes a first configuration for inserting the distal end of the elongated member within an opening and a second configuration for selectively securing the elongated member within an opening. Also provided is a method of performing a transvaginal surgery. The method includes providing an access port including a retention mechanism configured to selectively retain the access port within the vagina of a patient, forming an incision in the wall of the vagina into the abdomen of the patient, inserting a distal end of the access port into the vagina and through the incision, and activating the retention mechanism to secure the distal end of the access port within the abdominal cavity of the patient.Type: GrantFiled: July 6, 2010Date of Patent: November 3, 2015Assignee: Covidien LPInventors: Stanislaw Marczyk, Russell Pribanic, Kevin Sniffin

Patent number: 9168053Abstract: A system for tissue dissection and retraction is disclosed herein. A tissue dissection assembly generally comprises an elongate body shaft, an actuation member movable relative to the elongate body shaft, and at least one dissector arm member having at least a first end attached to the elongate body shaft, wherein the at least one dissector arm member is adapted to reconfigure within a plane from a low profile to an expanded profile when urged via the actuation member, and wherein the at least one dissector arm is further adapted to dissect tissue within the plane. In use, the assembly dissects tissue within the plane typically by advancing the elongate body shaft into the tissue region where the dissector arm member or members are then reconfigured within the plane from its low profile to its expanded profile to thereby dissect the tissue region along the plane.Type: GrantFiled: August 29, 2011Date of Patent: October 27, 2015Inventor: John A. Cox

Patent number: 9149272Abstract: A suture passer guide that includes an elongate member having a longitudinal axis and defining a first proximal opening and a first distal opening. The first proximal and distal openings are substantially aligned with one another such that a suture passer can be extended through the first proximal and distal openings at an acute angle relative to the longitudinal axis of the elongate member. The suture passer guide can be configured to be passed through a central lumen of an endoscopic port.Type: GrantFiled: December 21, 2012Date of Patent: October 6, 2015Assignee: CooperSurgical, Inc.Inventors: Charles Sherts, Kerry Blair, Robert D. Auerbach, Mark Curtis, James Young

Patent number: 9138549Abstract: The invention relates to an insufflator with a supply connection (22) and a delivery connection (14) and a pressure and flow measuring device arranged between said connections (14, 22) for determining measured quantities characterizing a gas pressure at a delivery connection and a gas volume flow at the delivery connection. The pressure and flow measuring device comprises a multilayer board (20) which comprises on its interior at least one flow channel (26) that is connected at its input to the supply connection (22) and at its output (8) to the delivery connection (14). Arranged on the board (20) are pressure measurement sensors (32, 34) and electronic components (4, 6) for the wiring of the pressure measurement sensors.Type: GrantFiled: January 29, 2010Date of Patent: September 22, 2015Assignees: MGB ENDOSKOPISCHE GERAETE GMBH BERLIN, UNIVERSITAET ROSTOCKInventors: Lienhard Pagel, Stefan Gabmann, Johannes Tschepe

Patent number: 9138278Abstract: Suprapatellar systems, system components, and methods of operating on a tibial fracture of a patient are disclosed. A method can include making an incision proximal to a patella of a knee joint, forming an operation space, and inserting a portion of a retractor in the operation space to define an entry canal. The retractor can be inserted in a low profile configuration and, once positioned as desired by a surgeon, expanded to a high profile configuration. Expansion of the retractor can expand the operation space in at least one of an anterior-posterior direction or a medial-lateral direction and can increase a diameter of the entry canal. The method can further include inserting a trocar, having at least one guide hole, in the entry canal and guiding a guide pin through the at least one guide hole and into a tibia.Type: GrantFiled: May 3, 2013Date of Patent: September 22, 2015Assignee: Zimmer, Inc.Inventor: G. Karl Van Osten, III

Patent number: 9125657Abstract: One embodiment of the apparatus comprises a housing with a sheath portion projecting distally therefrom. The sheath portion has a sheath with a lumen, and a bearing surface in the sheath lumen or aligned with the sheath lumen, and located at or near a distal end of the sheath. The implant is at least partially positioned in the apparatus, and comprises an implant body and a tether connected to the implant body. The tether extends from the implant body distally within the sheath portion and around the bearing surface, where the tether changes direction, and extends back proximally from the bearing surface along and within the sheath portion. The apparatus is configured to move the first tether portion proximally and thereby draw the implant body distally along and within the sheath lumen.Type: GrantFiled: June 21, 2011Date of Patent: September 8, 2015Assignee: Covidien LPInventors: Miranda M. Ray, Hoa D. Nguyen, John W. Rodriguez
