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. ## Claims ### Claim 1 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. ### Claim 2 (depends on 1) The system of claim 1, wherein the suture includes a cradle configured to engage a contact portion of said anchor. ### Claim 3 (depends on 2) The system of claim 2, wherein said biasing body is configured to maintain a separation angle of said cradle. ### Claim 4 (depends on 3) The system of claim 3, wherein the biasing body includes at least one suture alignment guide configured to maintain said separation angle of said cradle. ### Claim 5 (depends on 1) The system of claim 1, wherein the driver comprises a first engagement portion, said anchor comprises a second engagement portion, and wherein said first and second engagement portions are configured to be coupled with each other so as to transmit torque therebetween. ### Claim 6 (depends on 1) The system of claim 1, wherein the biasing body is self-aligning with respect to said implant as said biasing force is applied. ### Claim 7 (depends on 1) The system of claim 1, wherein said driver is configured to rotate relative to said biasing body. ### Claim 8 (depends on 7) The system of claim 7, wherein said first end region includes a driver cradle configured to generally retain a portion of said shaft as said driver is rotated relative to said biasing body. ### Claim 9 (depends on 1) The system of claim 1, wherein said suture is configured to extend from said exterior portion of said anchor through i) a suture passageway within said biasing body, and ii) an opening at the first region, so as to interface with said driver. ### Claim 10 (depends on 9) The system of claim 9, wherein said biasing body comprises one or more lateral openings to receive said suture therein.
