Implantable tissue fastener and system for treating gastroesophageal reflux disease
First Claim
1. An implantable fastener for fastening layers of tissue together, comprising:
- an elongated support;
a distal anchor member having a first end portion connected to the support and a second end portion movable on the support, the distal anchor member being configured to be movable from a reduced profile position to a deployed position when a spacing between the first and second end portions is reduced;
a proximal anchor member having first and second end portions movable on the support, the proximal anchor member being configured to be movable from a reduced profile position to a deployed position when a spacing between the first and second end portions of the proximal anchor member is reduced, the proximal anchor member being spaced from the distal anchor member a distance sufficient to position the layers of tissue together between the proximal and distal anchor members; and
at least one retainer on a proximal end portion of the support, the retainer engaging one of the end portions of the proximal anchor member when at least the proximal anchor member is in the deployed position so that at least the proximal anchor member is retained in the deployed position.

Abstract
A system including an implantable fastener for fastening layers of tissue is disclosed. In one embodiment, the fastener includes a proximal anchor member and a distal anchor member each being movable from a reduced profile position to a deployed position. The anchor members are mesh structures capable of moving to the deployed position by reducing the axial spacing between opposite ends of the anchor members.
Methods of treating gastroesophageal reflux disease (GERD) are also disclosed. One of the methods includes placing the distal anchor member through a hole formed in the wall of the esophagus and through a hole formed in the gastric wall. The distal anchor member and the proximal anchor member are then placed in their deployed positions to fasten the wall of the esophagus and the gastric wall together between the anchor members.

11. An implantable fastener for fastening layers of tissue together, comprising:
-
a first anchor member having a distal end portion and a proximal end portion, the first anchor member being configured to be movable from a reduced profile position to a deployed position when a spacing between the proximal and distal end portions is reduced; a second anchor member having a proximal end portion and a distal end portion, the second anchor member being configured to be movable from a reduced profile position to a deployed position when a spacing between the proximal and distal end portions of the second anchor member is reduced; a connecting section connecting the proximal end portion of the first anchor member to the distal end portion of the second anchor member, the connecting section having a length sufficient to position the layers of tissue together between the first and second anchor members; an elongated support connected to the distal end portion of the first anchor member, the support being movable proximally in the proximal end portion of the first anchor member, in the connecting section, and in the second anchor member to place the first and second anchor members in the deployed positions; and at least one retainer on a proximal end portion of the support, the retainer engaging the proximal end portion of the second anchor member when the first and second anchor members are in the deployed positions. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
