Abstract

An H-type fastener for surgical tissue. The fastener has a central biasing member. The biasing member has a first end and a second end. Anchor members are mounted to each end.

Claims

1. An H-type fastener for tissue, comprising

a central biasing member, said central biasing member having a first end, a second end, and a cross-section, said central biasing member capable of being elastically deformed from a first relaxed resting position to a second extended position;

a first anchoring member mounted to the first end of the biasing member; and

,

a second anchoring member mounted to the second end of the biasing member,

wherein the cross-section comprises a pair of squares, each square having corners and a diagonal, the squares connected to each other at one of said corners along the diagonal.

2. An H-type fastener for tissue, comprising

a central biasing member, said central biasing member having a first end, a second end, and a cross-section, said central biasing member capable of being elastically deformed from a first relaxed resting position to a second extended position;

a first anchoring member mounted to the first end of the biasing member; and

,

a second member mounted to the second end of the biasing member,

wherein the cross-section comprises a pair of circles having circumferences connected at one point about their circumferences.

3. An H-type fastener for tissue, comprising

an elongated central connecting member, said elongated central connecting member having a first end, a second end, and a cross-section;

a first anchoring member mounted to the first end of the connecting member, said first anchoring member capable of being elastically deformed from a first relaxed resting position to a second extended position; and

,

a second anchoring member mounted to the second end of the connecting member, said second anchoring member capable of being elastically deformed from a first relaxed resting position to a second extended position,

wherein the anchoring members have a V-shaped configuration comprising two angulated legs connected at an apex and wherein the apex of each anchoring member is mounted to an end of the elongated central connecting member.
