Tunnelling lead terminal having a disposable sheath

摘要

A monitoring system includes a lead having a terminal covered by a removable sheath. In one embodiment, the lead has a first end coupled to an implantable electrode and a second end which includes a terminal for coupling to a mating terminal. The sheath prevents bodily fluids from contacting the terminal as the lead is tunneled under a patient's scalp. After the terminal exits the scalp, the sheath is removed from the terminal to allow its connection to the mating terminal. <IMAGE>
