Abstract: A method for manufacturing a header for an implantable medical device such as a pacemaker which contains an advantageous molded design with encapsulated wires and conductive features. The header including a specifically formed lead lock member in which a plurality of collets residing in bores in the molded housing are used to retain and lock implantable leads in place without the use of set screws.

Abstract: A header assembly and method to incorporate electrical contacts and seals into a header are described. The header and method include properly positioning a stack of electrical contact housings and seals or seal assemblies in the header and maintaining the electrical contact housings and the seals in the header with pins inserted in the header from outside the header through axially arranged holes in the header to interface corresponding grooves of the electrical contact housings.

Abstract: A method for providing a header assembly for connecting an implantable medical device to at least one conductor lead terminating within a patient intended to be assisted by the medical device is provided. The implantable medical device is comprised of at least one feedthrough wire extending from the control circuitry and through a wall of the housing. The header assembly is comprised of an insulative body that is mountable on the housing of the medical device. The insulative body supports at least one conductor subassembly comprising a terminal that is directly connectable to the conductor lead, an intermediate conductor comprising a distal end connected to the terminal and a proximal end connected to a connector. Methods for making the header assembly and for connecting the header assembly to the implantable medical device are also disclosed.

Abstract: A header assembly for connecting a conductor terminating at a body organ with an implantable medical device is described. The header assembly comprises a base plate, a feedthrough subassembly disposed in the base plate and comprising a ceramic-to-metal seal with first and second feedthrough wires passing through the ceramic-to-metal seal; a first electrically conductive terminal connected to a distal end of the first feedthrough wire and having a first lead opening sized to receive a first portion of a lead for the conductor; a second electrically conductive terminal connected to a distal end of the second feedthrough wire and having a second lead opening sized to receive a second portion of the lead for the conductor; a body of polymeric material molded in a two-part construction to encase the conductive terminals and their feedthrough wires except for a first bore communicating from outside the polymeric body to the first and second lead openings aligned in a first co-axial relationship.

Abstract: The present invention is directed to a header assembly attachable to a medical device for the purpose of connecting its output terminals to at least one lead, the lead terminating at a target organ or portion of the body intending to be assisted. A number of leads are connectable to the header, including single and coaxial leads. The header assembly may be molded directly to the medical device or preformed and then attached to the device casing, either by mechanical fastener and/or chemical adhesive.

Abstract: A header assembly mounted to a medical device for connecting to at least one conductor lead terminating at a target organ or portion of the body intending to be assisted is described. The header assembly comprises a body of polymeric material supporting at least one unitary conductor wire. The conductor wire connects between a feedthrough wire exiting the medical device and a terminal block into which the conductor lead plugs. Various structures are described for connecting the conductor wire to the feedthrough wire.
