Patent ID: 8747417

Claim:
A tool for operably coupling to an implantable cardiac electrotherapy lead and a stylet, wherein the implantable cardiac electrotherapy lead has a lead connector end at a proximal portion, a contact pin proximally extending from the lead connector end, and an active fixation helix tip at a distal portion, and wherein the tool operably couples to the lead connector end, the tool comprising: a handle having a first digit engagable member linearly displaceable along the handle; a worm gear operably coupled to the handle and first digit engagable member, wherein linear displacement of the first digit engagable member results in rotational displacement of the worm gear; an axle operably coupled to the worm gear and configured to operably couple with the contact pin, wherein rotation of the worm gear results in rotation of the axle; and a first feature that engages the lead connector end, wherein rotation of the axle causes the contact pin to rotate relative to the lead connector end; wherein the axle has a first toothed gear and the worm gear has a second toothed gear in toothed engagement with the first toothed gear.
