Abstract:
A soft, expandable, implantable device sized for spacing between small bones comprising a first smooth surface on which a first small bone may slide. Implant (700) includes an opening (704) (passage) extending through the device for promoting fibrotic development through the opening from a direction from both thumb metacarpal (202) and trapezium (204). Passage (704) is optionally distally positioned from a one-way inflation valve (706) included inside an inflation port (702) substantially limiting possible damage to the device due to the insertion pressure of an expansion fluid. An inflation cannula and/or needle may be attached to inflation port (702) and inflation valve (706) for introducing the expansion fluid into the device. Implant (700) is inserted in a deflated mode and is positioned so that thumb metacarpal (202) abuts distal side (703) of the device when expanded and trapezium (704) abuts proximal side (701). Both distal side (703) and proximal side (701) include a smooth surface for allowing relative movement of thumb metacarpal (202) and trapezium (204) with respect to device (700).
Abstract:
A mold assembly for the in situ formation of a prosthesis in an annulus located in an intervertebral disc space between adjacent vertebrae of a patient. The mold assembly includes at least a first mold having at least one interior cavity adapted to be located in the intervertebral disc space. At least a first lumen has a distal end fluidly coupled to the mold at a first location. One or more discrete reinforcing structures are located in the intervertebral disc space with the mold. One or more biomaterials are provided to be delivered to the interior cavity through the first lumen. The at least partially cured biomaterial, the reinforcing structures and the mold cooperating to form the prosthesis.
Abstract:
An implantable prosthesis device is disclosed. The prosthesis device comprises one or more compartments bounded by a substantially closed porous envelope made at least in part of non-woven polymer fibers, and a filler structure at least partially filling the compartment(s) and being made, at least in part, of non-woven swellable polymer fibers.
Abstract:
An intervertebral disc is expanded and injected by forming and dilating an opening in the disc annulus and introducing an inflatable member into the disc nucleus pulposus. The inflatable member location within the nucleus pulposus is verified and the inflatable member is gradually inflated for augmenting a space in the nucleus pulposus. The internal pressure and expansion of the inflatable member are monitored. The inflatable member is subsequently deflated and a biomaterial is injected into the augmented space.
Abstract:
A disc implant is provided which maintains intervertebral spacing and stability within the spine. In an embodiment, a disc implant may include three or more components. Components of the implant may imitate certain physiological movements associated with a healthy spine. In certain embodiments, the components of the implant may limit physiological movements to within certain ranges, imitating normal spinal movements.
Abstract:
Trapezium-methacarpalprosthetic implant that ensures stability of the implant without limiting the freedom of movement of the hand bones. In particular, this is achieved by the shape of an interposition element.This shape of the implant allows for a freer movement of the bones with respect to one another and with respect to the prosthesis itself.

Abstract:
In one aspect, an intervertebral prosthetic device for implantation within a disc space between adjacent first and second vertebral endplates includes a body including a main body with an outer surface bearing portion configured to interface with and articulate relative to one of the first and second vertebral endplates. It also comprises an orientation protrusion shaped in a manner to at least partially inhibit rotation of the body in the disc space. The body is sized in at least one direction to fit inside a boundary defined by a travel path of the first vertebra relative to the second vertebra, the travel path forming an arc about a center of rotation of the first vertebra, the travel path being spaced from the center of rotation a distance substantially equivalent to the distance from the center of rotation to the second vertebral endplate.
Abstract:
A vertebral disc prosthesis (50), a method for implanting and a deployment device (80) is provided. The prosthesis (50) is for deployment within the interior of the vertebral disc for restoring the functionality of the disc (e.g., the ability of the disc to transfer nutrients or otherwise survive, the ability of the disc to carry the required loads and absorb stress or the reduction of pain). The prosthesis (50) may be made of a material having a compression strength less than about 4 mn/m 2 and may include a grouping of multiple components that can be deployed as group.

Abstract:
Implants comprising a plurality of separate cortical bone units (10). which have been at least partially demineralized and are osteoinductive, are described herein. The implants can be used in methods for treating bone. Also, disclosed are methods for treating spinal conditions using these implants. The spinal conditions include but are not limited to repairing damage to or defects in the spine, such as fractures in a vertebral (30) body or degeneration of spinal discs.
