Anchors and method for securing suture to bone

摘要

A method for securing suture to bone comprises drilling a hole in a desired portion of bone at a desired procedural site, passing a strand of suture through a portion of soft tissue to be approximated to the portion of bone, and extending the free suture ends proximally from the soft tissue. The suture is loaded into an anchor implant. Using an inserter, on a distal end of which is attached the anchor implant, the anchor implant is manipulated into the bone hole. The suture is then tensioned to a desired level by pulling on the free suture ends, after the anchor implant is positioned in the bone hole. The free suture ends are wrapped about a suture cleat on an inserter handle once the desired tension level is achieved. A proximal anchor component is moved distally to engage with a distal anchor component to lock the anchor in place within the bone hole, and to lock the suture in place within the anchor. Then, the inserter is removed from the procedural site.

主权项

1. An anchoring system for securing suture to bone, comprising:
an implant comprising a suture securing aperture extending transversely through the implant from at least one side thereof, having a distal tip and a proximal end, and having external surface features for securing the implant within surrounding bone; a proximal member, having a proximal end which is proximal to the proximal end of the implant, said proximal member being movable distally to engage said implant and to fix the suture in place within said implant and relative to the bone; said implant further comprising an internal suture cavity having a tapered surface and extending axially along the implant, wherein one leg of a length of suture running through said implant extends axially along an external side of the implant, and a second leg of the length of suture is compressed against the proximal member and along the tapered edge of the internal suture cavity, axially along the internal suture cavity; and an inserter which is engaged with said proximal member to move said proximal member distally to engage said implant, and is removably connected to the proximal end of said implant; wherein said implant and said proximal member have mating surfaces which lock together when the implant and the proximal member are fully engaged.
