ABSTRACT:
An assembly of a primary and an auxiliary tool employed in implanting an electrical lead and its electrode in body tissue, the primary tool or device having a groove associated therewith for holding the electrode and the lead's conductor during implantation in a manner to avoid imparting torque to the lead and undue pressure upon the body tissue during release of the lead from the primary tool. The primary tool includes a leading end with a cavity for receiving a boot for the lead's helical electrode, the groove extending longitudinally for receiving the insulated conductor, and a longitudinally extending bore which communicates the groove for receiving the auxiliary tool. The auxiliary tool includes a body portion disposable within the bore, at least one fin extending radially from its body portion and disposable within the groove, and a terminal portion moveable into the cavity. Further, the primary tool has at least one laterally disposed slot communicating with the groove for receiving the fin of the auxiliary tool, which is inserted into the bore of the primary tool and rotated so as to place its fin into the slot thus holding the auxiliary tool with respect to the primary tool. Thereafter, the electrical lead is mounted upon the primary tool by disposing its boot into the cavity and its insulated conductor into the groove. Upon urging the auxiliary tool forward, its leading end moves into the cavity removing the boot therefrom and its fin is moved into the slot thereby removing the insulated conductor from the slot.
