Abstract
An H-type fastener for tissue. The fastener has a central spring member. The spring member has a first end and a second end. Tissue anchor members are mounted to each end. When placed in tissue, the spring member provides a compressive spring force upon tissue between the anchor members of the fastener.
Claims24
An H-type fastener for surgical tissue, comprising
- a central spring structure, said central spring structure having a first end, a second end, and a cross-section, said structure 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 spring structure;
- and,
- a second anchoring member mounted to the second end of the spring structure;
- wherein said spring structure when deformed from the resting position exerts a force on the anchoring members.
2 more elements
A method of approximating tissue, said method comprising the steps of
- a) inserting an H-type fastener into tissue, said tissue having opposed first and second sections, wherein the H-type fastener comprises
- a central spring structure, said central spring structure having a first end, a second end, a cross-section, a longitudinal axis, and a configuration, said structure capable of being elastically deformed from a first relaxed resting position to a second extended position;
- a first tissue anchor mounted to the first end of the spring structure;
- and,
- a second tissue anchor mounted to the second end of the spring structure;
- b) locating the first tissue anchor in or about one section of the tissue;
- c) elastically deforming the central spring structure to an extended position;
- d) locating the second tissue anchor in or about a second section of the tissue,
- thereby applying a compressive spring force to the tissue located between the first and second tissue anchors.
6 more elements
An H-type fastener for surgical tissue, comprising
- an elongated central connecting member, said member having a first end, a second end, and a cross section;
- a first anchoring spring structure mounted to the first end of the central member, said anchoring structure capable of being elastically deformed from a first relaxed resting position to a second extended position;
- and,
- a second anchoring spring structure mounted to the second end of the central member, said anchoring structure capable of being elastically deformed from a first relaxed resting position to a second extended position.
1 more element
A method of approximating tissue, said method comprising the steps of
- a) inserting an H-type fastener into tissue, wherein the H-type fastener comprises:
- an elongated central connecting member, said member having a first end, a second end, and a cross-section,;
- a first anchoring spring structure mounted to the first end of the central member, said spring structure capable of being elastically deformed from a first relaxed resting position to a second extended position;
- and,
- a second anchoring spring structure mounted to the second end of the central member, said spring structure capable of being elastically deformed from a first relaxed resting position to a second extended position;
- b) locating the first anchoring spring structure in or about one section of the tissue and deforming the first anchoring spring structure to an extended position;
- and,
- c) locating the second anchoring spring structure in or about an opposed section of the tissue, and deforming the second anchoring spring structure to an extended position,
- thereby applying a spring force to the tissue located between the first and second anchoring spring structures.
