    摘要: An implantable lead for sensing mechanical activity of a human heart has an insulating polymeric tube extending from a proximal end to a distal end of the lead, an electrical conductor provided in the lumen of the polymeric tube, and a sensor connected to the conductor at the distal end thereof. The polymeric tube is provided with a conductive surface layer along the inner face between the polymeric tube and the electrical conductor, the conductive surface layer being in electrical contact with this conductor. Accumulation of electrical charges between the electric conductor and the polymeric tube is thereby prevented.

    摘要: A fluid pressure sensor for a lead or catheter intended for placement in a living organism, such as a human heart, includes a rigid annular or tubular supporting structure and a piezoelectric element disposed on at least a portion of the outer surface thereof. The piezoelectric element delivers an electrical signal when subjected to a pressure variation, and exhibits circumferential sensitivity. The rigidity of the sensor is defined to satisfy predetermined criteria to ensure that the sensor, when sensing pressure transferred to the sensor through an on-growth of tissue on the sensor, which is at least 90% of the signal which the sensor would emit without the on-growth.
