Polymer reinforced coil conductor for torque transmission

摘要

A coil conductor for connecting an electrode near a distal end of a medical electrical lead with an implantable medical device (IMD) connected with a proximal end of the medical electrical lead includes a multi-filar coil and a torque enhancing sheathing. The multi-filar coil comprises a co-radially wound, multi-filar coil that has an inductance of approximately 1.5 muH or greater. The sheathing is extruded over to enhance the torque transmitting properties of the coil conductor.
