Interconnect for implantable medical device header

摘要

A modular header and method of fabricating same for making electrical connection between an array of feed-through pins extending through a wall of a hermetically sealed enclosure of an implantable medical device and lead connect or receptacles within the header in which the header is fabricated using a pre-formed molded header module, together with a set or harness of interconnected flexible conductors incorporated and sealed by an overlayer of medical grade polymer material. The assembled modular header is capable of complete pre-testing prior to assembly onto an implantable medical device.

1. A method of fabricating a modular header for providing electrical connections between an array of feed-through pins extending through a wall of a hermetically sealed enclosure of an implantable medical device and lead connector receptacles within a modular header assembled to said device comprising:
providing a pre-formed molded header module having paths therein to accept and incorporate a set of interconnected flexible conductors and connector blocks associated with lead connector receptacles; providing the set of interconnected flexible conductors each having a free end and a fixed end, wherein the fixed ends of the flexible conductors are connected to a top surface of an elongate removable common element and assembling said set of conductors into said paths by attaching the free ends thereof to corresponding connector blocks provided in said molded header module; performing an over-molding operation to incorporate and hermetically seal said conductors into said header structure; removing said common element to provide an array of spaced conductors configured and positioned to match and mate with said array of feed-through pins when said header is assembled to a compatible corresponding hermetically sealed enclosure.
