Patent number: 8613749Abstract: Various obesity treatment tools and methods are described herein, as well as treatments for other gastric-related diseases, e.g., GERD. Treatment includes reducing the size of the stomach pouch to limit the caloric intake as well as to provide an earlier feeling of satiety. This may be done by creating a smaller gastric pouch within the stomach directly from the interior of the stomach itself. The smaller pouches may be made through the use of individual anchoring devices, rotating probes, or volume reduction devices. A pyloroplasty procedure may also be performed to render the pyloric sphincter incompetent. A gastric bypass procedure may additionally be performed using atraumatic magnetic anastomoses devices so that sugars and fats are passed directly to the bowel while bypassing the stomach. Many of these procedures may be done in a variety of combinations. Treatment may create enforced behavioral modifications by discouraging the ingestion of high-caloric foods.Type: GrantFiled: December 5, 2003Date of Patent: December 24, 2013Assignee: Ethicon Endo-Surgery, Inc.Inventors: Mark E.

Publication number: 20130304100Abstract: A device for anastomosis of a tubular structure comprises first and second hollow members having a rigid part and an elastic part, and a connection member for interlocking the first and second members. The elastic parts are essentially circular rings, and are made of a polymeric, a biocompatible and/or biodegradable material. The rigid parts have an outer surface that is partly semi-circular in cross section, wherein the diameter at a non-connecting end is larger than or equal to the diameter at a connecting end, which ends in an edge. The first and second members are connected to each other so that a distance is formed between the elastic parts. A cavity is formed between the rigid parts and the connection member and the tubular structure, when arranged in the device.Type: ApplicationFiled: July 15, 2013Publication date: November 14, 2013Inventors: Anders Gronberg, Henrik Thorlacius

Patent number: 8579935Abstract: Surgical tissue fasteners and related deployment systems and methods are disclosed. A tissue fastener used to join multiple tissue layers includes a first member, a second member, and a connecting member connecting the first and second members. In some embodiments, the first and second members are configured to expand from a delivered state to a deployed state in which the fastener secures the tissue layers together. In other tissue fastener embodiments the connecting member has an elastic compressive spring force for applying a substantially constant force on the tissue layers for adjusting a length of the connecting member between the first and second members.Type: GrantFiled: February 17, 2009Date of Patent: November 12, 2013Assignee: Boston Scientific Scimed, Inc.Inventors: Robert B. DeVries, Kristian DiMatteo, Roy Sullivan, Marc Tassy, Jr., Barry N. Gellman, John E. Hutchins, John B. Golden, Kurt A. E. Geitz, William J. Shaw

Publication number: 20130292449Abstract: According to an aspect of the present disclosure, an apparatus for forming an anastomosis between adjacent sections of tissue is provided. The apparatus includes a body portion; an actuation assembly operatively supported at a proximal end of the body portion; an anvil assembly movably mounted at the distal end of the body portion for movement toward and away from the body portion; an approximation assembly extending between the body portion and the anvil assembly for moving the anvil toward and away from the tubular body portion; a dispersion assembly operatively associated with the approximation assembly, the dispersion assembly including at least one angled surface defining at least one channel interposed between the anvil assembly and the body portion and being configured to dispense a fluid therefrom; and at least one conduit for conducting wound treatment material to the dispersion assembly.Type: ApplicationFiled: July 3, 2013Publication date: November 7, 2013Inventors: Michael J. Bettuchi, Christopher J. Criscuolo

Publication number: 20130296899Abstract: Various obesity treatment tools and methods are described herein, as well as treatments for other gastric-related diseases, e.g., GERD. Treatment includes reducing the size of the stomach pouch to limit the caloric intake as well as to provide an earlier feeling of satiety. This may be done by creating a smaller gastric pouch within the stomach directly from the interior of the stomach itself. The smaller pouches may be made through the use of individual anchoring devices, rotating probes, or volume reduction devices. A pyloroplasty procedure may also be performed to render the pyloric sphincter incompetent. A gastric bypass procedure may additionally be performed using atraumatic magnetic anastomoses devices so that sugars and fats are passed directly to the bowel while bypassing the stomach. Many of these procedures may be done in a variety of combinations. Treatment may create enforced behavioral modifications by discouraging the ingestion of high-caloric foods.Type: ApplicationFiled: March 19, 2013Publication date: November 7, 2013Inventors: Mark E. Deem, Douglas S. Sutton, Hanson S. Gifford, III, Benard H. Andreas, Ronald G. French

Publication number: 20130296890Abstract: A medical device is disclosed for joining a first tubular organ (1), such as a blood vessel, to a second tubular organ (2), such as a blood vessel. The kit includes an external tubular scaffold (4) with a removable scaffold handle (7,18,19) and a clip (3). In use, the clip (3) and the external tubular scaffold (4) remain outside of the tubular organs (1,2) being joined. The clip (3) embraces a first longitudinal tubular section (6) of the external tubular scaffold (4) thereby holding together a longitudinal segment of an intima of the first tubular organ (1) and a longitudinal segment of an intima of the second tubular organ (2).Type: ApplicationFiled: December 15, 2011Publication date: November 7, 2013Inventors: Rossella Sgarzani, Rolf Spingler

Patent number: 8574246Abstract: An integrated anastomosis tool may include an effector that both makes an opening in the wall of a target vessel and connects a graft vessel to the target vessel. The effector may include a cutter assembly and a connection module that are independently actuatable. The connection between the graft vessel and the target vessel may be compliant, and may be achieved by suturing an end of the graft vessel to the side of the target vessel with the connection module.Type: GrantFiled: December 3, 2004Date of Patent: November 5, 2013Assignee: Cardica, Inc.Inventors: Theodore M.

Patent number: 8568429Abstract: The invention provides a device, assembly, and method for transoral endoscopic restoration of a gastroesophageal flap valve. The invention also provides a self-steering and self-closing tissue fixation device for tissue fixation, and an invaginator device for gripping and maneuvering tissue. The restoration device includes a longitudinal member arranged for transoral placement into a stomach, a tissue shaper carried on the longitudinal member that causes stomach tissue to assume a shape related to a gastroesophageal flap, and a tissue fixation device that maintains the shaped stomach tissue in a shape approximating a gastroesophageal flap. The tissue shaper may include a mold. The device may include the invaginator device for gripping and maneuvering esophageal tissue to aid restoration of the gastroesophageal flap, and may include the tissue fixation device.Type: GrantFiled: July 11, 2012Date of Patent: October 29, 2013Assignee: EndoGastric Solutions, Inc.Inventors: Stefan J.
