Patent number: 8029455Abstract: A method for controlling appetite by means of a satiation device is disclosed. The device, which includes a flexible webbing defining proximal and distal openings and a biasing structure, is attached to the patient's stomach with the proximal opening positioned adjacent and below the patient's gastro-esophageal junction. The biasing structure imparts pressure against the wall of the patient's stomach adjacent the gastro-esophageal junction.Type: GrantFiled: March 5, 2009Date of Patent: October 4, 2011Assignee: Barosense, Inc.Inventors: Richard S. Stack, William L. Athas, Richard A. Glenn, Dan Balbierz, John Lunsford, Michael S. Williams

Patent number: 8020741Abstract: Described herein are endoscopic staplers used to apply one or more fasteners to body tissue. In one embodiment, a fastener-applying device, which is preferably a stapler, is passed transorally into the stomach and used to plicate stomach tissue by engaging tissue from inside of the stomach and drawing it inwardly. In the disclosed embodiments, the tissue is drawn inwardly into a vacuum chamber, causing sections of serosal tissue on the exterior of the stomach to be positioned facing one another. The disclosed staplers allow the opposed sections of tissue to be moved into contact with one another, and preferably deliver staples for maintaining contact between the tissue sections at least until serosal bonds form between them. Each of these steps may be performed wholly from the inside of the stomach and thus can eliminate the need for any surgical or laparoscopic intervention.Type: GrantFiled: March 18, 2008Date of Patent: September 20, 2011Assignee: Barosense, Inc.Inventors: David Cole, Andrew Smith

Patent number: 7981162Abstract: A device for inducing weight loss in a patient includes a tubular prosthesis positionable at the gastro-esophageal junction region, preferably below the z-line. In a method for inducing weight loss, the prosthesis is placed such that an opening at its proximal end receives masticated food from the esophagus, and such that the masticated food passes through the pouch and into the stomach via an opening in its distal end.Type: GrantFiled: January 5, 2004Date of Patent: July 19, 2011Assignee: Barosense, Inc.Inventors: Richard S. Stack, Richard A. Glenn, William L. Athas, Michael S. Williams

Patent number: 7934631Abstract: A staple housing includes an array of staples each in a staple delivery position or “ready position” ready to be fired into target tissue. A staple driver is advanceable to drive the ready-position staples from the staple head into the tissue using staple pushers. During use, the staples in the ready positions are simultaneously fired into the target tissue using the staple pushers, forming an array of staples in the target tissue. After the array has been fired, one or more feed mechanisms within the staple housing advance a second group of staples from one or more staple storage locations into the ready positions in preparation for firing of the second group of staples.Type: GrantFiled: November 10, 2008Date of Patent: May 3, 2011Assignee: Barosense, Inc.Inventors: Daniel J.

Patent number: 7833280Abstract: A device for inducing weight loss in a patient includes a tubular prosthesis self-expandable from a collapsed position in which the prosthesis has a first diameter to an expanded position in which the prosthesis has a second, larger, diameter. In a method for inducing weight loss, the prosthesis is placed in the collapsed position and inserted into a stomach of a patient. The prosthesis is allowed to self-expand from the collapsed position to the expanded position and into contact with the walls of the stomach, where it induces feelings of satiety and/or inhibits modulation of satiety-controlling factors such as Ghrelin.Type: GrantFiled: April 8, 2008Date of Patent: November 16, 2010Assignee: Barosense, Inc.Inventors: Richard S.

Publication number: 20100276469Abstract: An improvement in a stapling device and method designed to capture a tissue fold between first and second members in the device and to staple and cut the fold to form a stapled tissue plication with a hole therein is disclosed. The improvement includes an engagement assembly in the first member movable from a retracted position in the first member to an extended position in the second member, and releasably attached to second member, an anchor assembly that includes the anchor, wherein (i) movement of the engagement assembly from its retracted to its extended position, through a tissue fold captured in the device between the first and second device members, is operable to engage the anchor assembly, and (ii) movement of the engagement assembly, with the anchor assembly engaged therewith, back toward its retracted position, is effective to pull at least a portion of the assembly through the hole in the stapled tissue plication formed by the device.Type: ApplicationFiled: May 1, 2009Publication date: November 4, 2010Applicant: BAROSENSE, INC.Inventors: Samuel T.

Publication number: 20100280529Abstract: A system, device, device and method for implanting a food restrictor in a patient's stomach, by coupling the restrictor to a plurality of tissue-plication anchors already placed in the stomach, are disclosed. The device includes an elongate shaft assembly for accessing the stomach transorally, and on which the restrictor can be carried, and a plurality of cable members mounted on the shaft assembly. The cable members are disposed on the shaft assembly along a distal section thereof, and releasably attached to the shaft assembly's distal end. After a cable member engages a tissue-plication anchor, retracting the cable is operable to first release the member from a holder at the the distal end of the shaft assembly, then pull a portion of the anchor through an aperture in the restrictor. This process is repeated for each anchor in the stomach for attaching the restrictor to the stomach.Type: ApplicationFiled: May 4, 2009Publication date: November 4, 2010Applicant: BAROSENSE, INC.Inventors: Samuel T.

Patent number: 7628821Abstract: A prosthetic device is described that is positionable within the gastro-esophageal junction region of a patient. The prosthetic device includes a proximal opening and a distal orifice that is adjustable in size prior to and/or following implantation. During use, the prosthetic device is attached to tissue of the gastro-esophageal junction region of the patient, with the device positioned such that food ingested by the patient passes from the esophagus through the proximal opening into the interior of the prosthetic device, and eventually exits the prosthetic device via the distal opening.Type: GrantFiled: August 2, 2005Date of Patent: December 8, 2009Assignee: Barosense, Inc.Inventors: Richard S.
