  • Publication number: 20150250472
    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.
