Abstract
A tool for inserting medical electrodes such as nerve-stimulating electrodes into tissue. An electrode is positioned fully within a tip of the tool so the tip end can be placed directly against the tissue to be penetrated for precise handheld positioning. A trigger on the tool is actuated to release a compressed spring in the tool to drive the electrode out of the tool tip into the target tissue. A viscous-damping means is provided in the tool to control electrode acceleration and velocity.
