Abstract
A implant delivery system for securing an implant to an anchor. The implant delivery system includes a driver including a shaft, a biasing body having a first end region configured to engage said driver and a second end region configured to engage a portion of an implant, and a suture extending between the anchor and the shaft of the driver. The driver may be rotated to reduce the length of the suture between the driver and the anchor and generate a biasing force urging the implant into engagement with the anchor. The biasing force is substantially not transmitted to the bone.

A system comprising:
- an implant system including:
- an anchor configured to be secured in bone beneath a patient's articular surface, said anchor having an inner passageway therethrough;
- and
- an implant configured to be secured to said anchor, said implant configured to replace a portion of said patient's articular surface;
- a suture having a first portion configured to be disposed around an exterior portion of said anchor, such that said suture is spaced apart from the inner passageway;
- and
- an implant delivery system comprising:
- a driver including a shaft;
- and
- a biasing body having a first end region configured to engage said driver, a second end region configured to engage a portion of said implant;
- wherein a second portion of said suture is configured to extend from said exterior portion of said anchor to interface with said driver, such that said biasing body is disposed between said first and second portions of said suture;
- wherein said driver is configured to rotate while engaged against said first end region to reduce a length of said suture between said driver and said anchor and generate a biasing force urging said implant into engagement with said anchor, and wherein said biasing force is substantially not transmitted to said bone.
