Patent number: 9247939Abstract: The present invention includes a method and apparatus for adhering tissue to one another. In an embodiment of the present invention the two tissues to be joined, for example the lower esophagus and the fundus of the stomach, are first placed adjacent to one another. Next a first restraint is placed near the outside surface of one of the tissues and a second restraint is placed near the outside surface of the other tissue. An irritant is then placed between the two adjacent tissues. The restraints, and consequently the tissue surfaces, are then drawn together. As the touching irritated tissue surfaces heal they will become bonded to one another and their need for the mechanical fastening of the restraints, to secure them together, will be diminished.Type: GrantFiled: December 5, 2013Date of Patent: February 2, 2016Assignee: Boston Scientific Scimed, Inc.Inventors: Charles H.

Patent number: 7074229Abstract: A method and device for performing endoluminal fundoplication are described. A device is inserted in the patient's stomach through the esophagus, including an unit adapted to grasp and pull a portion of the gastroesophageal junction into the stomach, and an unit adapted to move a portion of the fundus towards the esophagus. The device also can place fasteners to hold the gastric wall and the esophageal wall secured together, thus forming a valve between esophagus and stomach. An adhesive compound can be used to stabilize the juncture of the two walls.Type: GrantFiled: February 9, 2004Date of Patent: July 11, 2006Assignee: Scimed Life Systems, Inc.Inventors: Ronald D.

Patent number: 6302311Abstract: An endoscopic stapler includes a stapling head which is removably locatable on the distal end of an endoscope. The stapling head includes a stationary part which houses a removable staple cartridge and a movable part which includes an anvil for receiving and bending the ends of staples fired from the stationary part. The staple cartridge preferably houses two semi-circular rows of staples which are staggered relative to each other. The movable part is coupled to the stationary part by a threaded shaft which engages a worm gear in the stationary part and a first rotatable control wire is coupled to the worm gear. A substantially semi-circular firing cam is located proximal of the staple cartridge in the stationary part. The firing cam has an interior splined surface which is engaged by a spline gear coupled to a second rotatable control wire. In one embodiment, a knife is coupled to the firing cam so that tissue is cut subsequent to stapling.Type: GrantFiled: August 4, 2000Date of Patent: October 16, 2001Assignee: Boston Scientific CorporationInventors: Ronald David Adams, Lauren O.
