Construction for an implantable medical device having a battery affixed to the case

摘要

Designs and methods of construction for an implantable medical device employ an internal support structure. The single-piece support structure holds various electronic components such as a communication coil and a circuit board, and further is affixed to a battery, thus providing a subassembly that is mechanically robust. The support structure further provides electrical isolation between these and other components. A method of construction allows for the subassembly to be adhered to a case of the implantable medical device at the battery, and possibly also at the support structure. The battery includes an insulating cover having holes. An adhesive is used consistent with the location of the holes to affix the battery to the case without electrically shorting the battery to the case.

主权项

1. An implantable medical device, comprising:
a case; circuitry within the case configured to implement the functionality of the implantable medical device; a battery within the case electrically coupled to the circuitry; an insulating sleeve that surrounds at least a portion of the battery, wherein the insulating sleeve comprises at least one hole, and wherein the portion of the battery includes all surfaces of the battery other than the battery's terminal face; and a first adhesive, wherein the first adhesive affixes the battery to the case through the at least one hole, wherein the battery is electrically isolated from the case by the insulating sleeve and the first adhesive.
