PACING, SENSING OR DEFIBRILLATOR LEADS FOR IMPLANTATION INTO THE MYOCARDIUM
摘要
<p>An electrical lead for a cardiac device includes a body having a distal end sized for insertion through a catheter, first and second electrodes extending through the body, with each electrode terminating in a tip having proximal and distal ends and arranged to extend to an area of cardiac tissue. The tips include a fully insulated portion on the proximal and distal ends measuring in a range between 5 percent and 40 percent of the lengths of the tips, and further include an uninsulated intermediate section. The tip of the second electrode includes a helical section surrounding the first electrode and has an insulated portion on an inwardly facing portion surface facing toward the first electrode. The tip of the second electrode also includes a fully insulated portion on the proximal and distal ends measuring in the same or similar percentage range.</p>
