Implantable, self-retaining lead
First Claim
1. In an electrical lead for implantation in a patient which comprises separate first and second lead portions having conductor wire therein, electrically connected at respective ends within lead anchor means, the improvement comprising, said lead anchor means including a conductive metal sleeve, said sleeve including means for fixed retention of said first and second lead portions in electrical connection therewith, said sleeve having a bore portion which carries a conductive metal pin in electrically conductive relation to said sleeve, said pin being positioned in electrically conductive, engaging relation with the conductor wire of one of said lead portions, said sleeve also defining a lateral, threaded aperture which carries a threaded pressure member for pressing the conductor wire of said one lead portion into firm engagement with said pin for good electrical connection and firm retention.

Abstract
An electrical lead for implantation in a patient comprises separate first and second lead portions having conductor wire therein. The leads are electrically connected at respective ends within a lead anchor member. In accordance with this invention, the lead anchor has means for fixed retention of the first and second lead portions in electrical connection therewith so that an electrical signal passing through the lead passes through a conductive portion of the lead anchor between the first and second lead portions. The lead anchor has means permitting suture retention in a desired implanted position in the patient.
