Abstract
An implantable medical device having at least one lead connector. The lead connector has a collet-type mechanism. A bolt is securely affixed within the header of the implanted device. The bolt means has a central bore for receiving a pin of a lead, and fingers for contacting the end of the lead. Initial electrical contact is achieved by the bolt when the lead is inserted therein. A nut threadedly engages the bolt to compress the fingers against the lead. The nut is rotatably received within the header of the implanted device so that it can both tighten on the bolt and loosen therefrom. The nut is manipulated through a piercable septum.
