One piece header assembly for an implantable medical device
First Claim
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 terminal connectable to a lead of the conductor;
(b) a body supporting the terminal; and
(c) a first passageway extending into the body leading to the terminal and a second passageway extending into the body in communication with the terminal and the first passageway.

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.

13. A method for connecting an implantable medical device to a conductor terminating at a body organ intended to be assisted by the medical device, comprising the steps of:
-
(a) providing the medical device having a housing comprising at least a first and a second wall portions mateable together to provide the housing;
(b) positioning control circuitry, at least one electrical energy storage device and at least one feedthrough wire nested in the first wall portion, the feedthrough wire extending from the control circuitry through the first wall portion of the housing to a distal end of the feedthrough wire located outside the first wall portion, wherein the first wall portion is not mated to the second wall portion;
(c) molding a body of polymeric material supporting a terminal connectable to a lead of the conductor, wherein the body further includes a first passageway extending into the body leading to the terminal and a second passageway extending into the body in communication with the terminal and the first passageway;
(d) positioning the body on the first wall portion of the housing with the distal end of the feedthrough wire extending through the first passageway to contact the terminal;
(e) accessing the terminal through the second passageway to electrically connect the feedthrough wire to the terminal;
(f) mating the second wall portion to the first wall portion to complete the housing for the medical device; and
(g) connecting the lead of the conductor to the terminal.
