Abstract
A method and apparatus for surgically repairing a tear in soft tissue is disclosed. A plurality of collapsible tubes are positioned about the suture. The collapsible tubes are pushed through soft tissue and orthopedic mesh on opposite sides of a tear in soft tissue. When tension is applied to the suture, the tubes are compressed to fix the suture to the soft tissue and draw the soft tissue portions together.
Claims21
A suture anchor system, comprising:
- a suture anchor assembly, comprising:
- a suture;
- and
- a collapsible anchor coupled to the suture, the collapsible anchor including a middle section, a first end, and a second end;
- and
- an inserter carrying the suture anchor assembly, wherein said carrying includes the collapsible anchor in a folded delivery condition on a distal portion of the inserter with the suture extending back from the collapsible anchor toward a proximal end of the inserter,
- wherein the collapsible anchor is collapsible from the folded delivery condition to an anchoring condition inside a bone, the folded delivery condition permitting advancement of the collapsible anchor in a first direction through a tunnel formed in bone from a first end of the tunnel toward a second end of the tunnel, the anchoring condition forming an anchoring mass for contacting bone in the tunnel for inhibiting movement of the collapsible anchor back through the tunnel in a second direction opposite the first direction,
- wherein the collapsible anchor, in the folded delivery condition, includes the collapsible anchor folded along the middle section of the collapsible anchor such that, when the collapsible anchor in the folded delivery condition is advanced through the tunnel in the first direction, the middle section can lead the collapsible anchor through the tunnel with the first end and the second end of the collapsible anchor trailing the middle section through the tunnel,
- wherein the collapsible anchor being coupled to the suture includes the suture:
- (i) passing entirely through the collapsible anchor at a first location between the first end and the middle section of the collapsible anchor and again passing entirely through the collapsible anchor at a second location between the first end and the middle section of the collapsible anchor;
- and (ii) passing entirely through the collapsible anchor at a third location between the second end and the middle section of the collapsible anchor and again passing entirely through the collapsible anchor at a fourth location between the second end and the middle section of the collapsible anchor.

A suture anchor system, comprising:
- a suture anchor assembly, comprising:
- a suture;
- and
- a collapsible anchor coupled to the suture;
- and
- an inserter, the collapsible anchor mounted on a distal portion of the inserter with the suture extending back from the collapsible anchor toward a proximal end of the inserter,
- wherein the collapsible anchor being mounted on the distal portion of the inserter includes the collapsible anchor folded along a middle section of the collapsible anchor with a first end and a second end of the collapsible anchor extending back along the inserter away from the middle section such that, when the collapsible anchor is advanced through a bone tunnel, the middle section can lead the collapsible anchor through the bone tunnel with the first end and the second end of the collapsible anchor trailing the middle section through the bone tunnel,
- wherein the collapsible anchor being mounted on the distal portion of the inserter further includes the collapsible anchor exhibiting:
- (i) at least a first curved section and a second curved section along a first side of the collapsible anchor between the first end and the middle section of the collapsible anchor;
- and (ii) at least a third curved section and a fourth curved section along a second side of the collapsible anchor between the second end and the middle section of the collapsible anchor;
- the suture passing entirely through the collapsible anchor at least:
- (i) between the first curved section and the second curved section;
- and
- (ii) between the third curved section and the fourth curved section.

A suture anchor assembly for anchoring suture to bone, the suture anchor assembly comprising:
- a suture having a first free end and a second free end;
- and
- a collapsible anchor having a first anchor end and a second anchor end, the collapsible anchor received on the suture with the first free end and the second free end of the suture located outside the collapsible anchor, the collapsible anchor collapsible from a first condition to a second condition, the first condition of the collapsible anchor permitting advancement of the collapsible anchor in a first direction through a tunnel formed in bone from a first end of the tunnel toward a second end of the tunnel, the second condition of the collapsible anchor forming an anchoring mass for contacting bone in the tunnel for inhibiting movement of the collapsible anchor back through the tunnel in a second direction opposite the first direction,
- wherein the collapsible anchor, when in the first condition, is folded along a middle section of the collapsible anchor so that when the collapsible anchor in the first condition is advanced through the tunnel in the first direction the middle section can lead the collapsible anchor through the tunnel with the first anchor end and the second anchor end trailing the middle section through the tunnel,
- wherein the collapsible anchor, when in the first condition, includes:
- (i) a plurality of first anchor sections alternating with a plurality of second anchor sections along a first side of the collapsible anchor between the first end and the middle section of the collapsible anchor, wherein each of the plurality of first anchor sections is occupied by the suture, and wherein each of the plurality of second anchor sections is unoccupied by the suture and exhibits a curved shape;
- and (ii) a plurality of third anchor sections alternating with a plurality of fourth anchor sections along a second side of the collapsible anchor between the second end and the middle section of the collapsible anchor, wherein each of the plurality of third anchor sections is occupied by the suture, and wherein each of the plurality of fourth anchor sections is unoccupied by the suture and exhibits a curved shape.
