Patent number: 8257374Abstract: Described here are devices and methods for intussuscepting a portion of stomach tissue. Typically the intussusception is created at a position near, but distal to the gastroesophageal junction, and a pouch capable of storing a volume (from about 0 cc up to about 100 cc) is created proximal the intussuscepted tissue. In this way, the amount of food that may be ingested is reduced, helping to ameliorate GERD symptoms, and aiding in weight loss efforts. Some of the devices described here include an expandable member and at least one suction inlet. In these devices, the expandable member is expanded to create a proximal cavity into which the stomach tissue is pulled (e.g., using suction), thereby creating the intussusception.Type: GrantFiled: November 5, 2008Date of Patent: September 4, 2012Assignee: HourGlass Technologies, Inc.Inventors: Charles S.

Patent number: 8202293Abstract: An apparatus for delivering a closure element can include a splittable carrier tube and a splitter to split the tube. The carrier tube can have an outer surface retaining a closure element in a tubular configuration and can be split into radially-expandable flaps. A closure element has can have shape-memory body having a relaxed configuration with a planar-annular body defining a lumen with tines directed inwardly from the body. The clip can be held in a retaining configuration having a substantially asymmetrically-elongated tubular shape with a trapezoidal longitudinal cross-sectional profile and a proximal end having the tines being longitudinally directed with a first tine being more distally oriented compared to a substantially opposite second tine being more proximal, and retracting to a deploying configuration having a tubular shape with a rectangular longitudinal cross-sectional profile with the first tine being even with the second tine when being delivered.Type: GrantFiled: June 20, 2008Date of Patent: June 19, 2012Assignee: Integrated Vascular Systems, Inc.Inventors: Brian A.

Patent number: 8202284Abstract: An assembly for joining two vessel segments of a patient comprises a coupler formed of adjoining coupler halves, and a cuff having a large diameter portion and a small diameter portion. Each of the coupler halves includes an aperture for receiving an end of one of the vessel segments. One of the coupler halves comprises a connector element sized and shaped for connection to the other coupler half. The vessel segments are alignable in the respective coupler halves such that a path for fluid flow is formed therebetween upon connection of the coupler halves. The large diameter portion of the cuff is positioned over at least a portion of the coupler, and the small diameter portion of the cuff is positioned over one of the vessel segments. The cuff further includes a probe positioned at the small diameter portion. The probe is positioned within the cuff in a manner such that a signal is receivable therein corresponding to fluid flow through the vessel segment.Type: GrantFiled: February 8, 2008Date of Patent: June 19, 2012Assignee: Cook Medical Technologies LLCInventor: Chun Kee Lui

Patent number: 8197498Abstract: Methods and devices for treating obesity are provided, and more particularly, methods and devices for performing gastric bypasses are disclosed. In one exemplary embodiment a gastric bypass procedure is provided that includes forming a gastro-entero anastomosis between a stomach and an intestine and forming an entero-entero anastomosis between a portion of the intestine distal to the gastro-entero anastomosis and a portion of the intestine proximal to the gastro-entero anastomosis. A surrogate path is formed between the esophagus and the gastro-entero anastomosis to at least partially direct fluid from the esophagus to the intestine by way of the gastro-entero anastomosis, thereby bypassing the stomach. Devices useful in gastric bypass procedures that include anastomotic devices coupled to or integrally formed with a shunt. The devices can include a plurality of tubular bodies that are configured to have an adjustable length.Type: GrantFiled: November 6, 2008Date of Patent: June 12, 2012Assignee: Trinitas Ventures Ltd.Inventors: James E. Coleman, Christy Cummins

Publication number: 20120143229Abstract: Methods and devices for creating a seal in a vessel for performing multiple anastomoses. The device includes an expandable region at the shaft assembly distal end with a sealing membrane that spans the expandable region, and a corresponding clamping member moveable toward the expandable region. Once inserted into the vessel lumen the expandable region is deployed from a first low-profile position into a second expanded position, and positioned at the target site of the anastomoses. Movement of the distal end of the clamping member, which remains located outside the vessel, against the expanded region creates a seal at the target site allowing a blood-free, graft site area that is large enough to accommodate multiples anastomoses.Type: ApplicationFiled: December 20, 2011Publication date: June 7, 2012Applicant: VITALITEC INTERNATIONAL, INC.Inventors: Adam Gold, David J.
