PROBLEM TO BE SOLVED: To improve reliability of an implant relating generally to the field of medical devices, and, more specifically, to electronic leads for implants and tools for using such electronic leads. SOLUTION: An implantable coaxial lead includes a cable with male and female connectors. The cable includes inner and outer helical coils separated by an inner insulating tube and is accompanied with an outer insulating tube surrounding the outer helical coil. The male connector includes an outer conductive cylinder, a conductive pin and an insulator molded in between. In order to increase strength, a braided cylinder, infiltrated with rubber, is arranged at the juncture of the male connector and the cable. The female connector includes a cylinder formed by two conducting body elements 400, 402 and an intervening insulating body element 401. The female connector includes respective conductive tension elements 408, 416 configured to combine the male connector. A first seal 412 is provided between the conductive tension members, used for electrical isolation and tactile feedback. An insertion tool includes a cylinder with a hollow bore and a detachable head, and a rod for pulling the lead in the cylinder. COPYRIGHT: (C)2009,JPO&INPIT
