ABSTRACT:
An implantable electrode type lead assembly of the flexible type which is particularly adapted for implantation in the cardiac tissue for applications such as use with a pacemaker. The lead assembly has an electrode head which includes a fixation spiral for implantation into tissue. The spiral or rotation action of the electrode head is controlled by means of an elongated torsionally wound electrical coil conductor, the coil extending through the lead from the proximal to the distal end thereof and carried within a silicone tube which is co-extensive therewith, the tube having been especially treated to modify the slip characteristics of the internal diameter (ID) thereof for high efficiency torque transfer.
