Abstract:
An electrode assembly for a body implantable lead for the delivery of stimulation energy to a desired body site comprising:a tip electrode having a face adapted for positioning at least adjacent the desired body site; an elongated electrical conductor; a longitudinally extending weld electrode axially aligned with the tip electrode and at a proximal end engageably receiving one end of the elongated electrical conductor; and a connector member movably mounted on the weld electrode for selective engagement with the tip electrode and, when so engaged, for moving the tip electrode longitudinally between an unlocked position spaced from the weld electrode and a locked position fixed against longitudinal and rotational movement relative to the weld electrode; the weld electrode having an internal bore for receiving an elongated stylet selectively engageable with the weld electrode for implanting the electrode assembly at a desired body site and for explanting the electrode assembly from that body site.
