Claim:
1. A method of implanting a cardiac electrotherapy lead having an active fixation helix tip and a lead connector end having a contact pin mechanically coupled to the helix tip, wherein rotation of the contact pin causes rotation of the helix tip, the method comprising: providing the lead and a delivery tool; linearly displacing a first digit engagable member of the tool along a handle of the tool, wherein linear displacement of the first digit engagable member results in rotational displacement of a worm gear of the tool, and wherein the worm gear is operably coupled to the handle and the first digit engagable member; rotating an axle of the tool, wherein rotation of the worm gear results in rotation of the axle, wherein the axle is operably coupled to the worm gear and is configured to operably couple with the contact pin, and 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; and engaging a feature of the tool to the lead connector end, wherein rotation of the axle causes the contact pin to rotate relative to the lead connector end.
