One example provides a ferrule for an implantable medical device including a frame body having an upper surface and an opposing lower surface, an interior perimeter surface extending between the upper and lower surfaces for attachment to an insulator body, and an exterior perimeter surface extending between the upper and lower surfaces for attachment to a housing. A flange extends from the exterior perimeter surface and has an upper surface facing the upper surface of the frame body, the upper surface of the flange to engage an interior surface of a housing of the implantable medical device to limit a position of the housing along the exterior perimeter surface in a direction toward the bottom surface of the frame body, wherein a distance of the top surface of the flange from the top surface of the frame body is greater than and proportional to a thickness of the housing.

Ferrule for non-planar medical device housing

On example provides a ferrule for an implantable medical device including a first frame body having a first perimeter surface to make a brazed connection to a first medical device component, and a second frame body having a first perimeter surface to make a welded connection to a second medical device component. A spacer flange connects a second perimeter surface of the first frame body to a second perimeter surface of the second frame body, a thickness between a top surface and bottom of the spacer flange being less than a thickness between a top surface and a bottom surface of the first frame body such that the spacer flange is to deflect relative to the first frame body in response to forces being applied to the second frame body so as to reduce transmission of weld strain from the second frame body to the first frame body.
