First Claim
Patent Images
1. An implantable medical device, comprising:
- a case;
a support structure within the case;
an antenna within the case affixed to the support structure;
a battery within the case affixed to the support structure along a plane that is perpendicular to a first side of the case; and
a circuit board within the case affixed to the support structure, the circuit board comprising circuitry configured to implement the functionality of the implantable medical device,wherein the antenna and battery are electrically coupled to the circuit board, andthe battery is positioned entirely within a first area within the case, and the support structure, circuit board, and antenna are positioned entirely within a second non-overlapping area of the case, wherein the first and second areas are on opposite sides of the plane.

Abstract
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 support structure, and possibly also at the battery, without electrically shorting the battery to the case.
