Implantable lead having a steering distal guide tip
First Claim
1. A lead for implantation within an artery or vein of a human heart, said lead including a lead body having a longitudinal hollow core defining a longitudinal center axis and dimensioned for receiving a styler during implantation, a distal end, and a proximal end, an electrode affixed to said lead body and coaxially disposed with respect to said longitudinal center axis on said lead body and a guide tip positioned at said distal end of said lead body and including a tip end, said guide tip including a tapered portion forming said tip end wherein only said tip end is offset in a direction from said lead body longitudinal center axis so that when said lead body is rotated about a stylet during implantation, said tapered portion of said guide tip serves to steer the distal end of said lead body.

Abstract
A lead is provided which assists in the implantation of the lead within an artery or vein of a human heart. The lead includes a lead body having a distal end and a proximal end and at least one electrode carried by the lead body intermediate the distal end and the proximal end. The lead includes a guide tip carried by the lead body which extends distally from the lead body distal end. The guide tip includes a distal tip end and a tapered portion forming the distal tip end. The tapered portion is curved in a direction of curvature to offset the distal tip end in a direction from the longitudinal center axis of the lead body. The guide tip may further include tines or fibrotic tissue ingrowth sites for retaining the lead in place after implantation.
