Abstract
A pacing lead for connection between a pacemaker and a patient's heart, the pacing lead having conventional flexibility through proximal and distal lengths, and increased stiffness through an intermediate or middle length. The increased stiffness of the intermediate distance provides enhanced torsion characteristics, permitting easier and more accurate manipulation of the distal end of the lead. Increased stiffness of the intermediate length can be provided by a shrink tubing over the intermediate section of the lead coil, by a coating which is sprayed onto the coil to restrict its flexibility, or a tubing which is interference fit within the ID of the lead outer casing so as to constrain variation of the coil and increased stiffness. In each embodiment the friction between the coil and the outer casing is reduced through the intermediate middle length, so as to reduce the amount of twisting that is transmitted through to the tube casing, thereby enabling more efficient rotation of the anchor mechanism at the distal end of the lead.
