Abstract
A tool for implanting a pacing lead of the type having a fixation helix. The tool is provided a curved, elongated shaft with rotatable tongs mounted at its distal end. The tongs extend distally from the shaft and angle radially outward and slide against a bearing located in a distal portion of the shaft. A cable, rotatable and longitudinally movable relative to the shaft, extends through the shaft and is coupled to the tongs. A handle is mounted at a proximal end of the shaft and includes a mechanism for rotating the cable mechanism relative to the shaft and for moving the cable longitudinally relative to the shaft, so that the tons may grip rotate and release the tongs.
