Estimating the term…
A highly flexible implantable lead that offers improved flexibility, fatigue life and fatigue and abrasion resistance improved reliability, effective electrode tissue contact with a small diameter and low risk of tissue damage during extraction. In one embodiment the lead is provided with both defibrillation electrodes and pacing/sensing electrodes. For defibrillation/pacing leads, the lead diameter may be as small as six French or smaller. The construction utilizes helically wound conductors. For leads incorporating multiple separate conductors, many of the helically wound conductors are arranged in a multi-filar relationship. Preferably, each conductor is a length of wire that is uninsulated at about the middle of its length to create an electrode, wherein the conductor is folded in half at about the middle of the length to create first and second length segments that constitute parallel conductors.
An electrode for an implantable lead comprising
A method of making an electrode for an implantable lead wire comprising:
A method according to 18 wherein said outer insulation has a melt point and second wire is heated above said melt point.
An implantable lead having a length, comprising:
An Implantable cardioverter defibrillator lead body comprising a length having an insulated portion and an electrically conductive portion, wherein the Implantable cardioverter defibrillator lead body has a maximum diameter of about 2 millimeters or less.
An implantable lead comprising a distal tip wherein said tip includes a rotatable helical fixation member and a thread guide comprising a copolymer containing an elutable therapeutic agent.
An electrical connector, said connector comprising at least one contact ring, said contact ring having an integral leg extending distally from said contact ring for connection with a conductor wire.
