US 2014/0155948 A1 · OPTICAL FIBER-FINE WIRE LEAD FOR ELECTROSTIMULATION AND SENSING

Abstract

Various aspects of the present disclosure are directed toward an implantable electrostimulation device, a plurality of sensing and pacing elements, and a fine wire lead extending in a sealed relationship from the electrostimulation device and to the plurality of sensing and pacing elements. The fine wire lead includes multiple discrete conductors and a drawn silica or glass fiber core, a polymer cladding on the drawn silica or glass fiber core, and a conductive metal cladding over the polymer cladding. Additionally, the fine wire lead simultaneously delivers different electrical signals or optical signals between the sensing and pacing elements and the electrostimulation device.
