Patent number: 6837894Abstract: 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: March 26, 2002Date of Patent: January 4, 2005Assignee: SciMed Life Systems, Inc.Inventors: Charles H. Pugsley, Jr., Barry N. Gellman

Publication number: 20040225373Abstract: Endoluminally delivered tissue patches and related systems and methods for delivering the tissue patches for treating lesions of the alimentary tract are disclosed. A tissue patch includes a tissue implant imbedded in a substrate to form a first layer and a second layer of substrate on a top surface and a bottom surface of the tissue implant. A predetermined thickness of the first layer is different from a predetermined thickness of the second layer. A tissue patch may include a tissue implant imbedded in a substrate formed of a plurality of sections capable of being folded into a contracted state for endoluminal delivery to the lesion. A system for delivering a tissue implant includes a catheter having an expandable member at a distal end portion, a carrier placed around the expandable member, and the carrier configured to expand from a contracted state to an expanded state and to receive the tissue implant.Type: ApplicationFiled: May 5, 2003Publication date: November 11, 2004Applicant: Scimed Life Systems, Inc.Inventors: Charles H.

Publication number: 20040225247Abstract: Endoluminally delivered tissue patches and related systems and methods for delivering the tissue patches for treating lesions of the alimentary tract are disclosed. A tissue patch includes a substrate, a tissue implant attached to the substrate, and a protective liner covering at least a portion of the tissue implant. A method includes providing a tissue patch having a tissue implant attached to a substrate and a protective liner covering at least a portion of the tissue implant. The tissue patch is formed into a contracted state and inserted into a lumen containing the lesion. The tissue patch then is positioned in the vicinity of the lesion. After removing the protective liner to reveal the tissue implant, the tissue implant is placed in the lesion.Type: ApplicationFiled: November 14, 2003Publication date: November 11, 2004Applicant: Scimed Life Systems, Inc.Inventors: Charles H.

Patent number: 6692507Abstract: An impermanent biocompatible fastener comprises a male portion and a female portion. The male portion includes a base member and a pair of male members. The male members extend downwardly from the base member, each male member comprising a post and a head disposed at the bottom end of the post. The female portion includes a base member and a pair of sleeves. The sleeves extend upwardly from the base member, each sleeve defining a bore adapted to receive a head from a corresponding male member and having an inner flange. The flange extends into the bore and is engageable with the head once the head has been inserted past the flange to inhibit withdrawal of the head from the bore. Except for a biodegradable outer coating on each of the two heads, the fastener is made entirely of a non-bioabsorbable material.Type: GrantFiled: August 23, 2001Date of Patent: February 17, 2004Assignee: SciMed Life Systems, Inc.Inventors: Charles H.
