1. A customizable implant configured for placement between joint surfaces of a joint, the implant comprising:
- an expandable body;
a hollow cavity within said body;
a first exterior surface portion for opposing a first joint surface;
a second exterior surface portion for opposing a second joint surface;
the first exterior surface portion being substantially flat relative to the first joint surface;
the second exterior surface portion substantially matching a contour of the second joint surface; and
wherein the implant is configured for placement between the joint surfaces such that when expanded the second exterior surface portion engages the second joint surface and the first exterior surface portion provides the joint with a range of motion.

- 21. A hollow device for forming an articular repair system in situ, the device having an aperture for injecting material into the device and a lumen coupled to the device to receive the material and form said articular repair system to treat a facet joint, uncovertebral joint or costovertebral joint in the spine, wherein the hollow device includes a first wall section and a second wall section formed from non-common materials so as to impart a varying expansion resulting in a desired shape of the device in an inflated state, and wherein the first wall section includes an exterior surface portion that substantially matches an articular surface portion.

24. A method of forming a customizable implant configured for placement between joint surfaces, the method comprising:
-
providing a first hollow device having walls with a variable wall thickness that imparts a varying expansion resulting in a desired shape of the device in an inflated state and having an exterior surface portion that substantially matches a corresponding surface portion of the joint; inserting the first hollow device into a target joint; and injecting material into the first hollow device to achieve the inflated state and the desired shape so as to form an implant to treat a facet joint, uncovertebral joint or costovertebral joint in the spine, wherein the exterior surface portion of the device engages the corresponding surface portion of the joint when the device is in the inflated state. - View Dependent Claims (25, 26, 27, 28)

29. A method of forming a customizable implant configured for placement between joint surfaces, the method comprising:
-
providing a first hollow device having a first wall section and a second wall section formed from non-common materials so as to impart a varying expansion resulting in a desired shape of the device in an inflated state and having an exterior surface portion that substantially matches a corresponding surface portion of the joint; inserting a first hollow device into a target joint; and injecting material into the first hollow device to achieve the inflated state and the corresponding desired shape so as to form an implant to treat a facet joint, uncovertebral joint or costovertebral joint in the spine, wherein the exterior surface portion of the device engages the corresponding surface portion of the joint when the device is in the inflated state. - View Dependent Claims (30, 31, 32, 33)

34. A method of forming a customizable implant configured for placement between joint surfaces, the method comprising:
-
providing a first hollow device having a varying expansion resulting in a desired shape of the device in an inflated state and having an exterior surface portion that substantially matches a corresponding surface portion of the joint; inserting the first hollow device into a target joint; injecting material into the first hollow devices to achieve the inflated state and the corresponding desired shape so as to form an implant to treat a facet joint, uncovertebral joint or costovertebral joint in the spine; and anchoring the implant at least in part by engaging the exterior surface portion with the corresponding surface portion of the joint. - View Dependent Claims (35, 36, 37, 38, 39, 40, 41)
