One piece header assembly for an implantable medical device
First Claim
Patent Images
1. A header assembly for connecting a conductor terminating at a body organ with control circuitry and at least one electrical energy storage device of an implantable medical device, the header assembly comprising:
- (a) a first electrically conductive terminal having a first lead opening sized to receive a first portion of a lead for the conductor;
(b) a second electrically conductive terminal having a second lead opening sized to receive a second portion of the lead for the conductor;
(c) a body of polymeric material molded as a single piece to support the first and second terminals in a partially encased relationship so that the first and second terminals are prevented from moving by the polymeric material;
(d) a first bore communicating from outside the polymeric body to the first and second lead openings aligned in a first co-axial relationship;
(e) a first passageway extending into the body leading to the first terminal, and wherein a second passageway extends into the body in communication with the first terminal and the first passageway;
(f) a third passageway extending into the body leading to the second terminal, and wherein a fourth passageway extends into the body in communication with the second terminal and the third passageway; and
(g) wherein the first and third passageways are in communication with the second and fourth passageways and provide for receiving a feedthrough wire that is directly contactable to the respective first and second terminals.

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.
