ABSTRACT:
The electrical leads for cardiac stimulators comprise an insulated electrical conductive section and a lead-in securing section including a helical member which may be screwed into the heart muscle. Preferably, there is interposed between these two sections a non-insulated electrical conducting section which becomes embedded in the heart upon insertion of the electrical lead. If there is any breakage between the lead-in securing section and the rest of the electrical lead, electrical impulses are still supplied to the heart by the cardiac stimulator.
An insertion tool is provided to attach the electrical lead to the heart.
