Abstract:
A method of strengthening a case in which an implantable medical device is hermetically sealed, comprising the steps of:(a) providing a case having a cavity therein and an open end through which the cavity is accessible;(b) placing a metal band on the open end of the case, the case and metal band being matable;(c) hermetically sealing the case and metal band together forming a housing structure;(d) inserting a potting material while in a fluid state into the open end of the housing structure so as to substantially fill the cavity;(e) inserting a component assembly into the open end of the structure so as to be immersed within the fluid potting material within the cavity; the potting material thereby filling voids within the cavity between the component assembly and the housing structure;(f) curing the potting material; and(g) hermetically sealing a header to the metal band of the housing structure, thereby forming an hermetically sealed implantable device, the header having a plurality of hermetically sealed feed-through posts that provide external communication with the component assembly sealed within the device.
