Abstract:
A partial resurfacing implant (30b) for use in repairing an articular cartilage defect site (29) that includes a top articulating portion (30) having a top surface (30a) that is configured with at least one radius of curvature to approximate the surface contour of the articular cartilage surrounding the defect site. The implant also includes a supporting plate (32) that has a top surface and a bottom surface. The top surface is attached to the top articulating portion by a locking mechanism (33). The bottom surface of the supporting plate is constructed to facilitate the insertion of the implant into the defect site. Extending from the bottom surface of the supporting plate is at least one implant fixation portion (31). The at least one implant fixation portion is integrally connected to and is oriented about normal relative to the bottom surface. A method of repairing an articular cartilage defect with the partial joint resurfacing implant is also disclosed.
Abstract:
The present invention relates to an insertion system for medical devices and to surgical methods for the implantation of the same. In one embodiment, the implantation system includes a guide wire and an insertion tool. The insertion tool includes a longitudinal bore extending therethrough for receipt of the guide wire. A portion of the longitudinal bore of the insertion tool mates with the outer surface of the guide wire to rotationally lock the insertion tool and the guide wire. Additionally, the medical device to be inserted includes a longitudinal bore for receipt of the guide wire. Similarly, at least a portion of the longitudinal bore of the medical device may also mate with the outer surface of the guide wire to rotationally lock the medical device and the guide wire. The rotational locks allow for rotation of the insertion tool to result in corresponding rotation of the medical device via rotation of the guide wire. In another embodiment, the insertion system further includes a needle having an eyelet for receiving and positioning filaments attached to the medical device.
Abstract:
A date display assembly for an electronic device, the assembly comprising a ones date ring assembly (21), a tens date disc assembly (6) and a gear assembly (7B) comprising a four-legged blocking star (12) and a four-legged driving star (11). The driving star (11) is used for driving the tens disc (6) and the blocking star (12) is used to maintain the proper orientation of the tens disc.
Abstract:
The present invention relates to improved methods for reducing pain and organ dysfunction using bioadhesive, bioresorbable, anti-adhesion compositions made of intermacromolecular complexes of carboxyl-containing polysaccharides, polyethers, polyacids, polyalkylene oxides, multivalent cations and/or polycations. The polymers are associated with each other, and are then either dried into membranes or sponges, or are used as gels, fluids or microspheres. Compositions are useful in surgery to prevent the formation and reformation of post-surgical adhesions. The compositions are designed to breakdown in-vivo, and thus be removed from the body. Membranes are inserted during surgery either dry or optionally after conditioning in aqueous solutions. Anti-adhesion, bioadhesive, bioresorptive, antithrombogenic and physical properties of such membranes and gels can be varied as needed by carefully adjusting the pH and/or cation content of the polymer casting solutions, polyacid composition, the polyalkylene oxide composition, or by conditioning the membranes prior to surgical use. Membranes and gels can be used concurrently. Antiadhesion compositions may also be used to lubricate tissues and/or medical instruments, and/or deliver drugs to the surgical site and release them locally.
Abstract:
A method of making an implantable scaffold for repairing damaged or diseased tissue includes the step of suspending pieces of an extracellular matrix material in a liquid. The extracellular matrix material and the liquid are formed into a mass. The liquid is subsequently driven off so as to form interstices in the mass. Porous implantable scaffolds fabricated by such a method are also disclosed.
Abstract:
Orthopaedic devices (10, 30, 40, 50, 70, 110, 240, 260, 310, 340) are disclosed. The devices (10, 30, 40, 50, 70, 110, 240, 260, 310, 340) includes a part that is made of extracellular matrix material that has been hardened. One method of hardening the extracellular matrix is to comminute naturally occuring extracellular matrix and dry the cimminuted material. The hardened extracellular matrix material can be machined to form a variety of orthopaedic devices (10, 30, 40, 50, 70, 110, 240, 260, 310, 340).
Abstract:
A method for the repair of a cartilagenous tissue defect, a cartilage repair device (20) and a method of making a cartilage repair device are disclosed. In the method for the repair of a cartilagenous tissue defect, a device comprising a scaffold, for example an extracellular matrix material, is implanted into the defect, and a biological lubricant (234) is administered to the defect. The device (20) comprises a scaffold (100), for example a naturally occurring extracellular matrix material, and a biological lubricant (234).

Abstract:
A wearable electronic device for conveying information in an analog manner at least in part by the use of at least one display hand positioned on the dial side of a dial, wherein the wearable electronic device uses the display hand(s) to convey information that is stored in the controller of the device and/or provided by sensors and/or an external transmitter. An actuation mechanism, preferably a stepper motor, is used to rotate the display hands in the clockwise and/or counterclockwise directions in predefined increments to convey the information.
