Implantable medical device feedthroughs and housings

摘要

Embodiments are generally directed to a feedthrough for an implantable medical device. The feedthrough comprises an insulator having one or more conductors extending therethrough that is hermetically connected (joined) to a housing of the implantable medical device. More specifically, the housing includes an aperture and the insulator is configured be positioned in the aperture. Braze material is configured to be positioned in one or more indentations in at least one of the housing or the insulator such that the braze material is disposed in the indentations between the insulator and the housing.

1. An apparatus comprising:
a housing having an aperture extending through the housing, wherein a housing sidewall substantially surrounds the aperture; an insulator configured to be positioned in the aperture and comprising one or more conductors extending therethrough; and a braze washer having a top flange configured to abut a surface of the housing and one or more first protrusions extending from the top flange and configured to be positioned in one or more indentations in at least one of the housing sidewall and the insulator such that the one or more first protrusions are disposed in the indentations between the insulator and the housing sidewall, wherein the one or more first protrusions are configured to be positioned in the housing prior to positioning of the insulator in the aperture, and wherein the one or more first protrusions provide resistance during insertion of the insulator such that the insulator is press-fit into the aperture and the braze washer.
