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. Pugsley, Jr., Barry N. Gellman

Patent number: 8043331Abstract: An embodiment of the invention includes a method of fastening together two tissue portions. The method may include positioning a medical device adjacent a region of tissue having two tissue portions. The medical device may include a male member and a female member having a first bioabsorbable material overlying one of a non-bioabsorbable material and a second bioabsorbable material. The first bioabsorbable material may have a first degradation rate, and the second bioabsorbable material may have a second degradation rate slower than the first degradation rate. The method may also include inserting the male member inside the female member so as to inhibit withdrawal of the male member from the female member with the two tissue portions between the male member and the female member.Type: GrantFiled: October 6, 2008Date of Patent: October 25, 2011Assignee: Boston Scientific Scimed, Inc.Inventors: Charles H.

Patent number: 8034048Abstract: A tissue patch for treatment of a lesion in an alimentary tract of a patient includes a tissue implant having a top surface and a bottom surface. The tissue patch also includes a substrate completely surrounding the tissue implant such that the substrate forms a first layer on the top surface and a second layer on the bottom surface. At least one of the first and second layers contacts the respective top or bottom surface and is entirely bio-absorbable so that the tissue implant touches an area of the patient's tissue upon dissolving of the at least one of the first and second layers. The first layer has a first predetermined thickness and the second layer has a second predetermined thickness different from the first predetermined thickness.Type: GrantFiled: May 5, 2003Date of Patent: October 11, 2011Assignee: Boston Scientific Scimed, Inc.Inventors: Charles H.
