ABSTRACT:
An elongate endocardial lead is disclosed which includes at least one distal electrode for sensing electrical activity in, and delivering electrical pacing pulses to, a patient's malfunctioning heart, a plurality of proximal terminal pins for coupling the lead to a pacemaker device, and a distal pressure sensor for sensing haemodynamic pressure within the heart. The pressure sensor comprises an integrated circuit chip having a layer of piezo-resistive material and a non-conductive base member, with the layer of piezo-resistive material being carried by the base member and having a pressure sensing diaphragm area therein exposed to ambient pressure. The base member and layer of piezo-resistive material are constructed and arranged so as to form a hermetically sealed chamber therebetween, with the chamber being at substantially atmospheric pressure and being substantially coextensive with the pressure sensing diaphragm area. The lead further includes coil wire conductors for coupling the integrated circuit chip and electrodes to various ones of the proximal terminal pins, so that a central lumen is provided in the lead throughout a major portion of the length thereof to facilitate passage of a stylet therethrough for actuating a device at the distal end of the lead to fix the lead to tissue of the heart.
