Abstract
Abstract An implantable electrical device, including a sealed case and a connector assembly, and a method for making the same are disclosed. The sealed case has electrical circuitry therein and has at least one insulated electrical-feed-through coupled to the circuitry. The feed-through member extends from the interior of the case to the exterior of the case and includes an external electrical terminal. The connector assembly has an apertured housing adapted to receive the proximal end portion of an electrical lead in sealing engagement with the housing. The connector assembly also has at least one electrical contact therein adapted to be engaged by a terminal of the electrical lead, and at least one insulated feed-through member coupled to the contact and extending from the interior of the assembly to the exterior of the assembly, the feed-through member including an external electrical terminal. The feed-through members of the sealed case and the connector assembly interconnect the connector assembly and the case together in such a manner that the external terminal of the feed-through member on the assembly electrically contacts the external terminal of the feed-through member on the case. The sealed case and the connector assembly are separately fabricated and, as a final step in the manufacture of the device, they are adhesively bonded together, with the external terminal of each in electrical contact with the external terminal of the other.

Claim 2
Dependent Claim
193 words
An implantable electrical device comprising: a sealed case having electrical circuitry therein and having at least one insulated electrical-feed-through member coupled to said circuitry and extending from the interior of said case to the exterior of said case, said feed-through member including an electrical terminal carried externally of said case; a connector assembly having an apertured housing adapted to receive a proximal, electrical-terminal-carrying, end portion of an electrical lead in sealing engagement with said housing, whereby the interior of said connector assembly is sealed from the exterior thereof when in engagement with the electrical lead, said connector assembly having at least one electrical contact therein adapted to be engaged by a terminal of the electrical lead and having at least one insulated feed-through member coupled to said contact and extending from the interior of said assembly to the exterior of said assembly, said feed-through member including an electrical terminal carried externally of said assembly; and means for fastening said connector assembly and said sealed case together in such a manner that the external terminal of the feed-through member on the assembly electrically contacts the external terminal of the feed-through member on the case.
Claim 3
Dependent Claim
22 words
A device according to claim 1, wherein said fastening means comprises an adhesive that bonds said connector assembly to said sealed case.
Claim 4
Dependent Claim
