Abstract
The pacing lead comprises a catheter and first and second conductors in the catheter. A tip electrode is fixed to the distal end of the catheter and in electrical contact with a distal end of the first conductor within the catheter. The catheter has an opening in the wall thereof with a bared end portion of the second conductor extending through the opening, out of the catheter and around the catheter. A thin walled electrode sleeve made of a rhenium/tungsten alloy is positioned about and in direct electrical contact with the bared end portion of the second conductor and is compressed about the conductor end portion and the catheter to an extent where the outer diameter of the sleeve is substantially the same as the outer diameter of the catheter. The method for making a pacing lead comprises the steps of: fixing a tip electrode onto the distal end of a flexible catheter; connecting a distal end of a first wire conductor fed through the flexible catheter to the tip electrode; feeding a second wire conductor part way into the flexible catheter and through an opening in the wall of the catheter; baring the distal end portion of the second wire conductor; coiling the bared end of the second wire conductor about the catheter; positioning an electrode sleeve made of a rhenium/tungsten alloy over the coiled bared conductor end portion and catheter; and compressing the sleeve over the coiled bare wire conductor end portion such that the outer diameter of the sleeve is substantially the same as the outer diameter of the catheter.
