Abstract
Official abstract text for this publication.
Apparatus for generating, applying and maintaining compression to a site in a human or animal body, the apparatus comprising: a staple comprising: a bridge configured to be elastically bendable; a first leg connected to the bridge by a first hinge region configured to be elastically bendable; and a second leg connected to the bridge by a second hinge region configured to be elastically bendable; wherein the first hinge region comprises a first hole configured to mate with a first element of a delivery device and the second hinge region comprises a second hole configured to mate with a second element of a delivery device; and wherein the first and second legs are angled toward one another when they are in an unstrained state; whereby, when the staple is mounted to a delivery device so that the first hole of the first hinge region mates with a first element of a delivery device and the second hole of the second hinge region mates with a second element of a delivery device, and when the delivery device applies a force to the bridge of the staple so as to reconfigure the bridge of the staple, the first and second legs are pivoted away from one another toward a parallel disposition.
First claim
Opening claim text (preview).
What is claimed is: 1. A delivery device comprising: a) a body having an internal threaded region configured to mate with a threaded screw; b) a handle mounted to a proximal end of the threaded screw; and c) a plunger; wherein when the threaded screw is advanced into the body i) a distal end of the threaded screw pushes against a proximal end of the plunger, and ii) a distal end of the plunger is configured to engage and bend an elastic bridge of a releasably mounted staple. 2. The delivery device of claim 1 , wherein the staple comprises nitinol. 3. The delivery device of claim 1 , wherein the staple comprises polyether ether ketone (PEEK). 4. The delivery device of claim 1 , wherein the distal end of the plunger engages a proximal surface of the staple. 5. The delivery device of claim 1 , wherein side surfaces of the bridge of the staple are substantially flat. 6. The delivery device of claim 1 , wherein the staple is distal of the threaded screw. 7. The delivery device of claim 1 , wherein the staple and the threaded screw do not contact each other. 8. A delivery device comprising: a) a body having an internal threaded region configured to mate with a threaded screw; b) a handle mounted to a proximal end of the threaded screw; and c) a plunger; wherein when the threaded screw is advanced into the body i) a distal end of the threaded screw pushes against a proximal end of the plunger, and ii) a distal end of the plunger is configured to engage and bend an elastic bridge of a releasably mounted staple to become more linear. 9. The delivery device of claim 8 , wherein the staple comprises nitinol. 10. The delivery device of claim 8 , wherein the staple comprises polyether ether ketone (PEEK). 11. The delivery device of claim 8 , wherein the distal end of the plunger engages a proximal surface of the staple. 12. The delivery device of claim 8 , wherein side surfaces of the bridge of the staple are substantially flat. 13. The delivery device of claim 8 , wherein the staple is distal of the threaded screw. 14. The delivery device of claim 8 , wherein the staple and the threaded screw do not contact each other.
