Abstract
An implantable medical lead includes a sensor capsule coupled to a lead body through which a sensor bus extends to couple with the sensor capsule. The sensor bus includes an elongate coil conductor, an elongate cable conductor extending within the coil conductor, and a material, positioned between the cable conductor and the coil conductor, which has a relative dielectric coefficient less than approximately 10.

20. An implantable medical electrical lead, comprising:
-
a lead body including a proximal end;
a sensor capsule coupled to the lead body; and
a sensor bus coupled to the sensor capsule and extending through the lead body to the lead body proximal end, the sensor bus comprising;
an elongate coil conductor, an elongate cable conductor extending within the coil conductor and electrically isolated from the coil conductor, an average gap between the cable conductor and the coil conductor, and means to reduce a capacitance between the cable conductor and the coil conductor over an implanted life of the lead, the means comprising a polymer material having a dielectric coefficient less than approximately 10 and filling greater than approximately 50% of the average gap between the cable conductor and the coil conductor. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
