Patent number: 10252024Abstract: A method of forming a fenestrated tubular support member includes determining a first iso-stiffness curve corresponding to a first function of beam length versus ring width for the first stiffness; determining a second iso-stiffness curve corresponding to a second function of beam length versus ring width for the second stiffness; determining an iso-volume curve corresponding to a third function of beam length versus ring width for a given fenestration volume; identifying a first intersection point where the iso-volume curve intersects the first iso-stiffness curve; and identifying a second intersection point where the iso-volume curve intersects the second iso-stiffness curve. The first section ring width and first section beam length are determined from the first intersection point, and the second section ring width and second section beam length are determined from the second intersection point.Type: GrantFiled: April 5, 2016Date of Patent: April 9, 2019Assignees: STRYKER CORPORATION, STRYKER EUROPEAN HOLDINGS I, LLCInventors: Clay Northrop, Ted Layman, Stephen Porter, James Paul

Patent number: 9974926Abstract: A tubular support member located in a distal portion of an elongate flexible medical device is provided with a plurality of wall openings, e.g., axially-spaced, substantially transverse slots, formed therein to thereby increase a flexibility of the support member. A layer of sealing material overlays an outer surface the support member so as to provide a sealed portion of the support member including the wall openings, the sealing material having respective flexible invaginations formed therein overlaying the wall openings in the support member so that the sealing material does not substantially impede flexibility of the support member.Type: GrantFiled: July 15, 2015Date of Patent: May 22, 2018Assignees: Stryker Corporation, Stryker European Holdings I, LLCInventors: Clay Northrop, Ted Layman, James Paul

Patent number: 7371215Abstract: A device, system and method for diagnosing and treating a patient is provided where a functional device is attached to a stomach wall. The device in one embodiment provides electrical stimulation of the stomach wall. The device may also have other functional aspects such as a sensor for sensing various parameters of the stomach or stomach environment, or a substance delivery device. The implant may be programmed to respond to sensed information or signals. The device may be modular with a portion of the device accessible for removal and replacement. In one embodiment, an endoscopic delivery system delivers the functional device through the esophagus and into the stomach where it is attached the stomach wall with the assistance of a suction used to stabilize the tissue of the stomach wall. The device includes a chamber for receiving tissue of the stomach wall for attachment where a vacuum pressure is applied through the chamber to draw the tissue into the chamber.Type: GrantFiled: July 9, 2004Date of Patent: May 13, 2008Assignee: Intrapace, Inc.Inventors: Olivier Colliou, Kevin Nason, Harm TenHoff, Mir A.
