  • Patent number: 10314597
    Abstract: An ankle arthroplasty system may have a talar prosthesis and a tibial prosthesis, each of which has an articular surface and a bone engagement surface. Each bone engagement surface may have an anterior-posterior curvature and a medial-lateral curvature with a convex shape. A burr with a rotatable cutting element may be used to form a prepared surface on the talus or the tibia to receive the corresponding prosthesis. A cutting guide may be used to guide motion of the burr; the cutting guide may include a base and an arm movably coupled to the base. One of the base and the arm may have a guide surface, and the other may have a follower that slides along the guide surface to constrain motion of the burr such that the prepared surface has at least one concave curvature and one convex curvature.

  • Patent number: 9622803
    Abstract: An orthopedic screw is used in a fixation device for treating fractures. The device has a body with holes to accept the bone screws. The bone screws have a layer of bioresorbable material on a surface portion of the head of the screw contiguous with the shaft. Engagement between the bone screws and the body is initially through the bioresorbable material, which engagement rigidly fixes the relative angular orientation between the bone screws and the body when the device is applied to a bone. As the bioresrobable material is resorbed the angular relation between the bone screws and the body is no longer rigidly fixed, thereby effecting a transformation from rigid osteosynthesis to flexible osteosynthesis to allow micromotion between the bone fragments which promotes healing.

The knotless suture anchor has an integrated flexible element that is formed as a plastic part within the knotless suture anchor's body. The free end of the flexible element terminates near a suture eyelet and can be compressed by a driver rod that is inserted into the knotless suture anchor to allow for insertion of a suture. With the flexible element compressed by the driver rod, the suture can be passed through the eyelet(s). When the driver rod is withdrawn, the flexible element expands thereby pinching the suture against the eyelet(s). If the driver rod is reinserted, the flexible element is recompressed and the suture can thereby be released or adjusted.

A skirt depends from a distal end of the body member. The skirt defines one or more distally opening slots and an abluminal surface of the skirt includes one or more transverse ribs proximate to a distal end of the skirt. A retaining ring includes a luminal surface having one or more transverse recesses proximate to a distal end of the luminal surface and one or more walls extending inwardly from the luminal surface. The slots accommodate the walls and the recesses accommodate the ribs to attach the body member to the retaining ring when the distal end of the skirt is inserted into a proximal end of the retaining ring.

  • Patent number: 8961575
    Abstract: A button and attached suture loop for CMC repair. A suture strand is threaded through holes in the button to attach the button to the suture. The suture ends are then brought together (by being swaged, spliced or cinched together, for example) to form the suture loop comprising a continuous, uninterrupted suture loop with a single strand of swaged-together ends. The swaged-together ends are attached to a suture passing instrument such as a K-wire (Kirschner wire) that is also used to drill a hole through adjoining metacarpals (for example, the first and second metacarpals). The swaged-together ends of the suture are then passed through the drill holes in the first and second metacarpals, and the ends of the suture are pulled until the button abuts one of the first and second metacarpals. A second button is used to secure the cut suture ends to the other metacarpal.

  • Patent number: 8961604
    Abstract: A fixation implant and associated methods are presented. The fixation implant includes a shaft extending from a first end portion to a second end portion and having an intermediate portion therebetween. The intermediate portion is generally smooth and the end portions are threaded. The method includes use of the fixation implant for repair of a metapodial phalangeal joint of a human extremity. The method includes: forming a bone tunnel in a bone; approximating material near the bone tunnel; and threading the fixation implant into the bone tunnel in interference fashion to secure the material relative to the bone tunnel. The fixation implant may be cut such that the end portion is flush with the bone.

  • Patent number: 8956394
    Abstract: A woven retention device for interfacing with a bone surface includes interwoven filaments forming a tubular lattice with protuberances distributed on interior and exterior surfaces of the lattice at a predetermined spatial relationship. The protuberances are formed by intersecting interwoven filaments. The retention device receives and surrounds a fastener. In a first, relaxed state, the retention device has multiple combinations of filament cross-section geometries at the intersection points, and the multiple combinations of filament cross-section geometries form multiple protuberance thicknesses. In a second state when surrounding at least a portion of the fastener, the retention device distributes pressure from the fastener to multiple points of contact on the exterior surface of the retention device such that a spatial relationship of the protuberances changes as a function of bone density of the bone surface and as a function of an interfacing surface shape of the fastener.

  • Patent number: 8945192
    Abstract: Implants for forming a positive connection with human or animal parts include a material, such as thermoplastics and thixotropic materials, that can be liquefied by means of mechanical energy. The implants are brought into contact with the tissue part, are subjected to the action of ultrasonic energy while being pressed against the tissue part. The liquefiable material liquefies and is pressed into openings or surface asperities of the tissue part so that, once solidified, the implant is positively joined thereto. The implantation involves the use of an implantation device that includes a generator, an oscillating element, and a resonator. The generator causes the oscillating element to mechanically oscillate, and the element transmits the oscillations to the resonator. The resonator is used to press the implant against the tissue part to transmit oscillations to the implant.
