DEPLOYMENT TOOL FOR DISTAL BONE ANCHORS WITH SECONDARY COMPRESSION
First Claim
1. A method of securing a first bone fragment to a second bone fragment, comprising the steps of:
- forming a bore through the first bone fragment in the direction of the second bone fragment;
advancing a fixation device comprising an elongate body, having a proximal end and a distal end, a helical anchor on the distal end of the elongate body and a proximal anchor, moveably carried by the elongate body, the elongate body and the proximal anchor having complementary retention structures configured to resist proximal movement of the proximal anchor with respect to the elongate body;
rotating the fixation device to engage bone in the second bone fragment; and
using a deployment device to apply a distal force to proximally withdraw the elongate body with respect to the proximal anchor.

Abstract
Deployment systems for deploying a bone fixation device are disclosed herein. One embodiment of a deployment system includes a syringe-shaped body configured to provide proximal traction to a bone fixation device in response to a compressive force between a finger grip and a plunger adapted to be engaged by the heel of a clinician'"'"'s hand. The device may include a collet for gripping a proximal pin of a fixation device. The deployment device may also include a tool that includes an elongate body with a distal tip adapted to rotationally engage a bone fixation device in order to axially rotate the fixation device. A further deployment device embodiment includes a cauterizing tip for heat-cutting an excess portion of a pin of a bone fixation device.
