Improved pacemaker fixation and performance using a modified finned porous surfaced tip lead

A simple method was used to modify the tip of a porous surfaced finned pacemaker lead. Comparison between the modified and the unmodified pacemaker electrodes was carried out in experimental animals and in humans. The incidence of early lead dislodgement, acute trapping and pacing thresholds was recorded. The study revealed improved overall performance with the modified pacemaker lead.
