ABSTRACT:
A rotatable pin, screw-in type lead assembly includes a radiopaque element proximate the distal tip of the lead assembly for permitting direct, rapid fluoroscopic verification of the amount of extension of the helix electrode relative to the tip. The radiopaque element is preferably in the form of a metallic ring having a porous, tissue-engaging outer surface which promotes rapid tissue ingrowth and consequent lead stabilization. The lead assembly further includes a low friction seal assembly operatively associated with a shaft carrying the helix electrode. The seal assembly reduces the number of turns of the lead assembly connector pin required to effect lead fixation or removal.
