摘要:
An implantable medical device (300) includes two conductive enclosures (310, 320) that are attached together, wherein the first enclosure (310) contains electronics (14), and the second enclosure (320) contains a power source (316). The second enclosure (320), all or a portion of which is located outside the first enclosure, includes an inner layer (321), an outer layer (322), and a header plate (351A), all of which are configured to provide redundant sealing for the power source. The inner and outer layers, formed by separate metal sheets nested one within the other, are preferably in direct mechanical and electrical contact. The first sheet (321), which forms the inner layer, approximately conforms to a profile of the power source, located therein, and the second sheet (322), which forms the outer layer, conforms to a profile of the first sheet. An insulative housing (201), which contains connector contacts of the device, is directly secured to the first and second conductive enclosures, for example, by mounting brackets (26). A first weld (27) extends around an entire perimeter of the header plate and joins the header plate (351A) to the edge of the first sheet (321), providing a seal for the contained power source. A second weld (25) extends around an entire perimeter of the header plate and joins the header plate (351A) to the second sheet (322), in proximity to the edge thereof, providing a redundant seal for the contained power source.L'invention concerne un dispositif médical implantable (300) qui comprend deux boîtiers conducteurs (310, 320) fixés entre eux, le premier boîtier (310) contenant un système électronique (14), et le second boîtier (320) contenant une source d'alimentation (316). Le second boîtier (320), dont tout ou partie se situe à l'extérieur du premier boîtier, comprend une couche interne (321), une couche externe (322) et une plaque de collecteur (351A), tous ces éléments étant conçus pour conférer une étanchéité redondante à la source d'al
