ANCHORING SYSTEM AND METHOD FOR SECURING A SUTURE TO A PRE-DRILLED BORE

摘要

An anchoring system can use an implant delivery device to deploy an implant into a pre-drilled bore, to secure one or more sutures between a threaded outer surface of an implant body and a wall of the bore. The implant delivery device can controllably rotate the implant about its longitudinal axis. The implant can further include a distal member positioned distal to the implant body and freely rotatable about the longitudinal axis. The implant delivery device can include a finger extending distally from a distal end of an inner shaft. The implant delivery device can controllably translate a wire between a distally extended position, at which the wire can form a closed loop with the finger and a distal end of the inner shaft, and a proximally retracted position, at which the wire can be at least partially retracted into the distal end of the inner shaft.

主权项

1. An anchoring system, comprising:
a cannulated implant including an implant body and a distal member that is rotatable relative to the implant body about a longitudinal implant axis, the implant body including a threaded outer surface; and an implant delivery device, comprising:
a cannulated outer shaft extending along a longitudinal delivery device axis, the cannulated outer shaft including a distal end configured to rotatably engage a proximal end of the implant body for rotating the implant body with the cannulated outer shaft for driving the cannulated implant into bone;an inner shaft slidably received in the cannulated outer shaft, wherein a distal end of the inner shaft is extendable distally beyond the distal end of the cannulated outer shaft such that, when the distal end of the cannulated outer shaft is engaging the proximal end of the implant body, the distal end of the inner shaft is extendable through the cannulated implant to a distance beyond the distal member of the cannulated implant;a finger extending distally beyond the distal end of the inner shaft; anda wire translatable through the inner shaft from a retracted position to an extended position, the extended position including a distal end of the wire extending a distance beyond the distal end of the inner shaft such that the wire and the finger form at least part of a closed loop for trapping suture.
