Abstract

Methods and devices are provided for anchoring a ligament or tendon to bone. In one embodiment, a surgical implant is provided having a sheath and an expander that is received within the sheath. Various delivery tools, including a sheath inserter and a driver, are also provided. In use, the sheath inserter can be used to position a tendon within a prepared bone hole, and it can be used to deliver the sheath with a guidewire coupled thereto into the bone hole. The driver can be provided for delivering the expander into the sheath. A loader can optionally be used to load the driver and expander onto the guidewire coupled to the implanted sheath.

Claims

1. A tendon anchoring system, comprising:

an anchor assembly having

a sheath with at least two sidewalls at least partially separated by at least first and second slots, the sidewalls defining an inner lumen therebetween, and

an expander configured to be received within the inner lumen of the sheath; and

an inserter tool having

an outer shaft with an inner lumen extending therethrough,

an inner shaft having first and second prongs formed on a distal end thereof, the prongs being sized and dimensioned to extend along the first and second slots in the sheath and to extend distally beyond a distal end of the sheath, and

a handle assembly coupled to a proximal end of the inner and outer shafts, the handle assembly having an actuator configured to axially move the inner shaft relative to the outer shaft to thereby move the prongs between an extended position in which the prongs extend distally beyond a distal end of the outer shaft, and a retracted position in which the prongs are retracted into the distal end of the outer shaft.

2. The tendon anchoring system of claim 1, wherein the outer shaft has a closed distal end having a central bore formed therein for receiving a guidewire and having first and second slots formed therein and extending radially outward from the central bore for receiving the first and second prongs.

3. The tendon anchoring system of claim 1, wherein the actuator is movable between a distal position on the handle assembly in which the prongs extend distally beyond the distal end of the outer shaft, and a proximal position on the handle assembly in which the prongs are retracted into the distal end of the outer shaft.

4. The tendon anchoring system of claim 3, wherein the actuator is biased to the distal position.

5. The tendon anchoring system of claim 1, further comprising a guidewire mated to the sheath, and a guidewire grasping element in the handle assembly configured to engage the guidewire.

6. The tendon anchoring system of claim 1, wherein the first and second prongs include a connector extending therebetween along a proximal portion of the prongs, the connector having a central lumen extending therethrough.

7. The tendon anchoring system of claim 1, wherein the sheath includes at least one anti-plunge tab extending radially outward from a proximal-most end thereof, and wherein a distal facing surface of the outer shaft includes at least one recess formed therein for seating the at least one anti-plunge tab.
