Patent number: 6813521Abstract: A medical electrical lead is provided that is readily manufactured using a minimal number of parts, has a reduced size and improved reliability during implantation and extraction. The lead includes a modular electrode head assembly that is joined to a lead body at a butt joint. The butt joint is stabilized in at least four possible ways: insulation tubing that spans the joint is bonded to the electrode head assembly; two cabled conductors extending the length of the lead body are coupled to the electrode head assembly; an electrode head alignment peg interlocks with and is bonded to the lead body; and a coil electrode is positioned across the butt joint on the outer diameter of the assembly and the lead body. The lead size is minimized by using a compact retraction stop mechanism, a low-friction, press-fit drive shaft seal, and a small diameter coiled conductor insulated by a thin-walled insulating tube.Type: GrantFiled: April 17, 2002Date of Patent: November 2, 2004Assignee: Medtronic, Inc.Inventors: Thomas C. Bischoff, Marc R. Helmick, Kathryn R. Parsons, Bret R. Shoberg, George M. Huepenbecker, Sandra F. Viktora, James J. Snyder

Publication number: 20020188340Abstract: A medical lead having a rotatable helical tip electrode helix and a retraction stop mechanism for preventing over-retraction of the helical tip electrode during lead repositioning. The retraction stop mechanism includes an engaging member positioned along a drive shaft of the lead and having a front surface, a flange portion extending along the front surface of the engaging member, and a retraction flange. Rotation of the drive shaft causes the flange portion to engage the retraction flange so that rotation of the drive shaft is absorbed by the conductor.Type: ApplicationFiled: April 17, 2002Publication date: December 12, 2002Inventors: Thomas C. Bischoff, Marc R. Helmick
