摘要：
A highly flexible implantable leadthat otters improved flexibility, fatigue life and fa-tigueand abrasion resistance improved reliability,effective electrode tissue contact with a small diame-terand low risk of tissue damage during extraction.In one embodiment the lead is provided with bothdefibrillation electrodes and pacing/sensing elec-trodes.For defibrillation/pacing leads, the lead di-ametermay be as small as six French or smaller. Theconstruction utilizes helically wound conductors.For leads incorporating multiple separate conduc-tors,many of the helically wound conductors are ar-rangedin a multi-filar relationship. Preferably, eachconductor is a length of wire that is uninsulated atabout the middle of its length to create an electrode,wherein the conductor is folded in half at about themiddle of the length to create first and second lengthsegments that constitute parallel conductors.
