ABSTRACT:
A body implantable lead including a stimulation electrode located at its distal end, a ring electrode located proximal to its distal end, and a pressure sensor. The lead is adapted to be used in conjunction with a stylet, which passes through the body of the lead from its proximal end to its distal end. The pressure sensor is integrated mechanically with the ring electrode, and is provided with a stylet tube which provides electrical connection to the tip electrode and allows passage of the stylet to the distal end of the lead. The pressure sensor includes a generally planar diaphragm, located within the ring electrode, communicating with the exterior of the ring electrode by means of one or more apertures. The stylet tube is mounted within the ring electrode adjacent to but insulated from the pressure sensor diaphragm.
