1. A method of manufacturing a medical electrical lead having a torque indicator comprising:
- loading a first material into a polymer to form a composite dispersion;
forming a first part having a hollow in a side wall;
introducing said composite dispersion into said hollow in said side wall to form a first stage assembly; and
assembling said first stage assembly into a medical electrical lead.

Abstract
A medical electrical lead and method of manufacturing such a lead for use in cardiac pacing, the lead having a distal end having an active fixation device such as a helix electrode (46) having a distal end and a proximal end, the tissue securing means extending from the lead body distal end, an electrical conductor (15) extending between the proximal and distal ends of the lead, and a longitudinally extending torque indicator (35 or 36) affixed to the lead body (10) proximal to the tissue securing means, the torque indicator (35 or 36) showing rotational movement or distortion of the torque indicator (35 or 36) under fluoroscopy.
