Orthopedic Fastener Patents (Class 606/300)
  • Patent number: 11229464
    Abstract: A driver-specific back-out prevention mechanism is disclosed that includes a screw and a body. A first driver can be used for coupling and decoupling the screw with the body, and a second driver can only be used for adjusting the position of the screw in the receiving body. The body includes a cavity for receiving a head of the screw, with the cavity having an inward flange. The screw includes upper and lower sockets, with a channel extending though the head from the lower socket and a lock body disposed in the channel. Engagement with the first driver allows the locking body to move such that the fastener can be inserted and removed from the body. Engagement with the second driver displaces the locking body such that the locking body interferes with the flange such that screw fastener cannot be removed from the body by the second driver.

  • 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.

  • Patent number: 9011533
    Abstract: Anterior cruciate ligament reconstruction methods and devices are designed to achieve an anatomically accurate double bundle anterior cruciate ligament reconstruction by using a single femoral and tibial tunnel. The method and devices reconstruct the two bundles of the anterior cruciate ligament in a single femoral and tibial tunnel using a bone-patellar tendon-bone graft. The methods and devices enable an accurate anatomical reconstruction of the anteromedial and posterolateral bundles by creating a single femoral and tibial tunnel as opposed to creating two tunnels in the tibia and femur.

  • Patent number: 9005184
    Abstract: For fixedly implanting a device for material or signal delivery or acquisition or a part of such a device in a human or animal body, an opening is provided in hard tissue of the body, the opening reaching through a hard tissue layer, e.g. through a cortical bone layer into cancellous bone underneath. The device includes a plug portion (P) and/or a cover portion (C) which includes a ring of a material having thermoplastic properties extending around the plug portion (P) or on a tissue facing surface of the cover portion (C). The opening provided in the hard tissue has a cross section at least in the area of its mouth that is adapted to the plug or cover portion such that the plug portion (P) can be introduced through the mouth of the opening or the cover portion (C) can be positioned over the mouth of the opening such that the ring extends around the opening, along its wall and/or on the hard tissue surface around its mouth.

  • Patent number: 8992585
    Abstract: A bone fixation system includes a compression bone screw and a washer for use with the bone screw in the reduction and fixation of bone fragments. The washer includes a frusto-conical body having a leading end, a trailing end, an exterior surface, an interior surface, and a central bore defined by the interior surface for receiving the bone screw. The interior surface is tapered resulting in the central bore's diameter being larger at the trailing end than at the leading end and the exterior surface has a greater taper angle than the taper angle of the interior surface.

  • Patent number: 8992537
    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.

    Abstract: Methods and devices are disclosed for manipulating alignment of the foot to treat patients with flat feet, posterior tibial tendon dysfunction and metatarsophalangeal joint dysfunction. An inflatable implant is positioned in or about the sinus tarsi and/or first metatarsal-phalangeal joint of the foot. The implant is insertable by minimally invasive means and inflatable through a catheter or needle. Inflation of the implant alters the range of motion in the subtalar or first metatarsal-phalangeal joint and changes the alignment of the foot.

  • Patent number: 8986347
    Abstract: Methods and apparatus described herein provide for a knotless suture anchor that captures and secures a suture by pinching on an inserted suture with a flexible element disposed within the knotless suture anchors body. 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.

    Abstract: A method for manufacturing a surgical implant. A metal layer is deposited onto a polyaryletherketone (PAEK) substrate by generating a series of pulses using a high power impulse magnetron sputtering process. Each pulse is applied in a series of micro pulse steps comprising (i) micro pulse on steps ranging from 10 ?s to 100 ?s and (ii) micro pulse off steps ranging from 5 ?s as to 400 ?s; at a repetition frequency ranging from 50-2000 Hz with 2 micropulses to 20 micropulses per repetition, a total pulse on time ranging from 25 ?s to 800 ?s for 5 minutes to 300 minutes at averaged power ranging from 200 W to 3000 W. The series of pulses are performed in a unipolar mode or a bipolar mode.

    Abstract: A distal loading receiver for a polyaxial bone screw includes a body member having a circumferential wall defining a bore disposed longitudinally through the body member. 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.
