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.
Claims31
A delivery system for securing an implant with an anchor, the delivery system comprising:
- a driver including a shaft, said driver configured to wind a portion of a suture, said suture configured to extend around a contact portion of said anchor disposed within a bone;
- and
- a biasing body having a first end region including a driver cradle configured to generally retain a portion of said shaft as said driver is rotated relative to said biasing body, and a second end region configured to engage a portion of said implant;
- wherein rotation of said driver applies a biasing force against said implant and said anchor to secure said implant with said anchor, and wherein said biasing force is substantially not transmitted to said bone.
A system comprising:
- an implant system including:
- an anchor configured to be secured in bone beneath a patient's articular surface;
- and
- an implant configured to be secured to said anchor, said implant replacing a portion of said patient's articular surface;
- at least one suture having a first portion configured to be disposed about a portion of said anchor;
- 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 and a second end region configured to engage a portion of an implant;
- wherein said driver is configured to wind a second portion of said suture 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.
A method of installing an articular surface implant in an excision site formed in a patient's bone, said method comprising:
- securing an anchor in said patient's bone within said excision site;
- and applying a biasing force against an implant to urge said implant into engagement with said anchor, wherein said biasing force is substantially not transmitted to said bone.
An implant system comprising:
- an implant body comprising:
- a load bearing surface having a contour substantially corresponding to a removed portion of a patient's articular surface;
- a bone facing surface;
- and
- a first fixation element;
- and
- an anchor configured to be secured in bone beneath said removed portion of said patient's articular surface, said anchor comprising a second fixation element;
- wherein said first and said second fixation element are configured to form a snap-fit connection therebetween.
