  • Patent number: 10064618
    Abstract: The present invention relates to devices and techniques for securing bone segments across a fracture site, and more particularly relates to bone staples for achieving compression between segments. A method and apparatus for interosseous bone fixation uses a compression staple, generally U-shaped, having a pair of legs with proximal ends interconnected by a bridge portion that is resilient and bowed, the staple having an initial configuration and capable of a tensioned configuration by spreading apart the legs by a certain amount causing the curvature of the bowed bridge to lessen and the legs to move towards each other with certain compressive spring force.

  • Patent number: 8974456
    Abstract: A dynamic tissue holding device for dynamically holding two tissue portions in contact with one another includes a resilient body having a spring and a band arranged for extending about the tissue portions to be held together. The band has a first end for attachment to a first attachment portion on the resilient body and a second end for attachment to a second attachment portion on the resilient body. Stops are disposed on portions of the resilient body for limiting both the compression and expansion of the spring. The compression of the spring is limited by engagement of two of the stops with one another and the expansion of the spring is limited by engagement of at least one of the stops with the spring.

  • Publication number: 20120024937
    Abstract: A method and apparatus for interosseous bone fixation uses a compression staple, generally U-shaped, having a pair of legs with sharp front ends and proximal ends interconnect by a bridge portion that is resilient and bowed, the staple having an initial configuration and capable of a tensioned configuration by spreading apart the legs by a certain amount causing the curvature of the bowed bridge to lessen and the legs urged towards each other with certain compressive spring force. A staple applicator supports and guides the staple and positions the tensioned staple with its pointed ends forward, adjacent an ejection port at the front of the applicator. A powered strike member is mounted for longitudinal movement and has a front end that will strike the rear of the tensioned staple with percussive force and eject it in tensioned configuration from the applicator.

  • Patent number: 6348054
    Abstract: A method and apparatus for interosseous bone fixation uses a compression staple, generally U-shaped, having a pair of legs with sharp front ends and proximal ends interconnected by a bridge portion, the staple having an initial configuration in which its generally straight legs converge with respect to each other, and capable of a tensioned configuration by resiliently moving and holding the legs in parallel relationship whereby the staple is urged towards its initial configuration with a certain compressive spring force. A staple applicator supports and guides the staple and positions the tensioned staple with its pointed ends forward, adjacent an ejection port at the front of the applicator. A powered strike member is mounted for longitudinal movement in the applicator and has a front end that will strike the rear of the tensioned staple with percussive force and eject it in tensioned condition from the applicator.
