View Patent ↗Improved methods, devices, systems and surgical techniques in the field of surgery and, in particular, improved anchoring devices and related surgical techniques for a variety of surgical repair procedures.
1. An anchor device for repairing soft tissue with a suture, comprising:
an anchor body comprising a generally U-shaped wall having a base and pair of opposed arms, the wall having an opening formed between the pair of opposed arms;
a prong member positioned at least partially within the opening, the prong member including a proximal portion formed integrally with the base of the generally U-shaped wall and a distal portion extending into the opening, the distal portion including a peripheral edge extending into the opening, the peripheral edge spaced apart from an inner edge of at least one of the pair of opposed arms by a minimum distance; and
an undercut retention tab formed on the distal portion, the undercut retention tab extending from the peripheral edge towards the inner edge of the at least one of the pair of opposed arms, with an undercut section facing towards the base;
the suture having a minimum cross-sectional width, the minimum cross-sectional width of the suture being greater than the minimum distance, whereby the at least one of the pair of opposed arms must flex relative to the prong member to thereby allow a loop of the suture to travel between the inner edge and the peripheral edge of the at least one of the pair of opposed arms.
2. The anchor device of claim 1 , wherein the generally U-shaped wall of the anchor body is substantially flat.
3. The anchor device of claim 1 , wherein the generally U-shaped wall of the anchor body comprises a convex surface on at least one side.
4. The anchor device of claim 1 , wherein at least one of the pair of opposed walls have a concave surface on at least one side.
5. The anchor device of claim 1 , wherein the prong member is substantially parallel to at least one of the pair of opposed walls.
6. The anchor device of claim 1 , wherein the prong member is fully within the opening.
7. The anchor device of claim 1 , wherein each of the pair of opposed arms include a bent distal end the prong member.
8. The anchor device of claim 7 , wherein the bent distal ends of the pair of opposed arms are bent towards each other.
9. The anchor device of claim 1 , wherein, after passage of the suture, the at least one of the pair of opposed arms flexes towards the prong member to lock the suture between the inner edge and the peripheral edge.
10. The anchor device of claim 1 , wherein the prong member includes a post extending outward from the prong member in a perpendicular direction.
11. An anchor device for repairing soft tissue with a suture, comprising:
an anchor body comprising a generally U-shaped wall having a base and pair of opposed arms, the wall having an opening formed between the pair of opposed arms;
a prong member positioned at least partially within the opening, the prong member including a proximal portion formed integrally with the base of the generally U-shaped wall and a distal portion extending into the opening, the distal portion including a peripheral edge extending into the opening, the peripheral edge spaced apart from an inner edge of at least one of the pair of opposed arms by a minimum distance; and
an undercut retention tab formed on the distal portion, at least a portion of the undercut retention tab being flexible, the undercut retention tab extending from the peripheral edge towards the inner edge of the at least one of the pair of opposed arms, with an undercut section facing towards the base;
the suture having a minimum cross-sectional width, the minimum cross-sectional width of the suture being greater than the minimum distance, whereby at least a portion of the undercut retention tab must flex relative to the prong member to thereby allow a loop of the suture to travel between the inner edge and the peripheral edge of the at least one of the pair of opposed arms.
12. The anchor device of claim 11 , wherein the generally U-shaped wall of the anchor body is substantially flat.
13. The anchor device of claim 11 , wherein the generally U-shaped wall of the anchor body comprises a convex surface on at least one side.
14. The anchor device of claim 11 , wherein at least one of the pair of opposed walls have a concave surface on at least one side.
15. The anchor device of claim 11 , wherein the prong member is substantially parallel to at least one of the pair of opposed walls.
16. The anchor device of claim 11 , wherein the prong member is fully within the opening.
17. The anchor device of claim 11 , wherein each of the pair of opposed arms include a bent distal end the prong member.
18. The anchor device of claim 17 , wherein the bent distal ends of the pair of opposed arms are bent towards each other.
19. The anchor device of claim 11 , wherein, after the suture travels between the inner edge and the peripheral edge, the flexible portion of the undercut retention tab flexes towards the inner edge to lock the suture between the inner edge and the peripheral edge.
20. The anchor device of claim 11 , wherein the prong member includes a post extending outward from the prong member in a perpendicular direction.
