Abstract
A tool for implanting a pacing lead into heart tissue has a pair of side-by-side beams pivoted together at the opposite ends thereof. The beams have jaws that grip a lead head supporting a helical electrode and a groove for accommodating a section of the lead extended from the head. A releasable lock interposed between the beams operates to hold the beams in jaw closed position to grip the head of the electrode. the lock has flexible fingers and a movable sleeve that allows one hand operation to selectively lock and release of the jaws. The helical electrode has an external layer of platinum black particles resulting in decreased electrical losses at the electrode-tissue interface, increased current density, lower stimulation thresholds, and increased amplitude of sensed electrical signals from the heart tissue.
