  • 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: 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.
