Abstract:
A body implantable lead assembly adapted to transmit electrical signals between a proximal end portion of the lead assembly and a distal end portion of the lead assembly and to thereby stimulate selected body tissue and/or sense electrical signals therefrom, the lead assembly having a longitudinal axis and comprising:a lead body lying along the longitudinal axis, the lead body having a proximal end and a distal end; a rotatable threaded element carried by the distal end of the lead body; an electrical conductor extending between the proximal end and the distal end of the lead body for transmitting the electrical signals, the conductor having a distal end; a sheath of insulative, biocompatible material enclosing the electrical conductor for electrically insulating the electrical conductor from body tissue and body fluids; and a tip electrode disposed at the distal end of the lead body, the tip electrode being electrically connected to the distal end of the electrical conductor, the tip electrode having a proximal end including a threaded bore, the rotatable threaded element being screwed into the threaded bore, wherein unscrewing of the rotatable threaded element disconnects the tip electrode from the electrical conductor and disengages the lead body from the tip electrode.
