Connector module having internal weld plates
First Claim
1. An implantable medical device for use with one or more implantable leads, the implantable medical device comprising:
- a housing portion for housing electronic circuitry, the housing portion including a feedthrough;
a connector assembly fixedly engaged with the housing portion and including one or more connector receptacles adapted to receive the one or more leads;
a plurality of connector blocks fixedly positioned within the connector assembly such that each forms a coupling for a one of the one or more leads within a one of the one or more connector receptacles;
a plurality of first conductors each including a first portion coupled to a one of the plurality of connector blocks and a second portion extending from the first portion;
a plurality of second conductors each including a first portion coupled to the electronic circuitry and a second portion extending from the first portion outward from the housing portion through the feedthrough;
a plurality of weld plates;
a plurality of first weld joints each formed between a one of the plurality of first conductor second portions and a one of the plurality of weld plates; and
a plurality of second weld joints each formed between a one of the plurality of second conductor second portions and a one of the plurality of weld plates.

Abstract
An improved system and method for interconnecting an electrical device to a connector is provided. A connector assembly includes at least one connector block. The connector block may be of a type adapted to mechanically and electrically couple to an electrical lead, although any other type of connector for forming an electrical contact may be employed. The connector assembly further includes at least one weld plate. A conductor such as a wire is routed between the connector block and the weld plate and electrically coupled to both structures. The connector assembly is adapted to be fastened to a device housed within an enclosure, such as an implantable medical device residing within a can. A conductor extending from circuitry within the housing may be electrically coupled to the weld plate to thereby form an electrical connection between the circuitry and the connector block.
