  • Patent number: 8496705
    Abstract: An anchor assembly for autologous or artificial tendon grafts comprises an insertion element and a stabilizing element. The insertion element has a stem and a head containing an aperture large enough to receive a graft. The stabilizing element is adapted to be embedded in bone, and comprises a sleeve with a cavity arranged to receive and hold the insertion element stem. In use, the stabilizing element is affixed in the bone, and the stem of the insertion element is placed therein. A tendon graft may be secured to the insertion element either before or after its placement in the stabilizing element. Two such anchors may be linked with one or multiple grafts, in either a two-ply or four-ply arrangement.

  • Patent number: 8328824
    Abstract: A device for snaring cord-like objects is provided. The device comprises a hollow shaft having a pointed distal end, a rod having a pair of wires attached to its distal end, the wires being spring biased away from one another, and housing. The rod and wires are located in the lumen of the shaft in reciprocally movable relationship with each other. The housing is attached to the proximal ends of the shaft and the rod so as to allow controlled movement of the rod and wires relative to the shaft. One of the wire-like elements defines a hook-shaped configuration at its distal end. The device allows the wire-like elements to be selectively located within the distal end of the shaft or in a configuration where the wire-like elements extend outwardly from the distal end of the shaft in flaring relationship to one another.

  • Patent number: 6830573
    Abstract: A surgical fastener system is disclosed. The system includes a surgical fastener, a surgical fastener holder sized and shaped to receive the surgical fastener at least partially therein, and a surgical fastener driver having a seat sized and shaped to frictionally receive a head of the surgical fastener therein. The fastener driver is constructed and arranged to selectively urge the fastener, and more particularly the fastener head, out of the seat. The surgical fastener driver thus includes an elongate body with the seat defined at an end thereof, and a drive piston disposed within the body. The drive piston has a first retracted position, and a second extended position in which at least a portion of the piston extends into the seat to urge the fastener out of the seat during usage. Also disclosed is a surgical fastener and a surgical fastener holder, respectively, for use with the system.

  • Patent number: 6524316
    Abstract: A bone fastener including an expandable member having an axial channel and an elongated element insertable into the axial channel is described. The expandable member is configured to be insertible into a bore drilled in bone. The distal end of the expandable member also may include a structure for axially releasing the expandable member from an emplacement device that places the expandable member into a bone opening. In one embodiment, the structure for axially releasing includes a frangible membrane capable of being severed from the expandable member during emplacement of the expandable member in a bone opening. A rivet for coupling an object to bone for use with an expandable member is also described. The distal end of the elongated element is shaped into a radially projecting portion adapted for engagement with a washer that contacts the object to be coupled. The washer, having upper and lower surfaces and a bore defined between the surfaces, is disposed around a portion of the shaft.

  • Patent number: 6402759
    Abstract: A surgical fastener driver has a handle and a tube extending therefrom. The handle defines a cavity therein. The tube is in communication with the cavity and is affixed to the handle. The tube extends outwardly from the cavity to a seat. The cavity is shaped so as to receive a surgical fastener therein. A piston, having a outward end, is disposed within the tube and extends from the cavity to the seat. The piston has a retracted position, in which the outward end does not extend into the seat, and an extended position, in which the outward end extends into the seat. A trigger is integrated with the handle and has a first state in which the piston is held in the retracted position and a second state in which the piston is released so as to allow the piston to move to the extended position. A driver, that is disposed within the cavity, exerts outward force on the piston so as to drive the piston into the extended position when the trigger is in the second state.
