Abstract
An electrochemical cell (10) suitable for use in an implantable medical device (110) includes a case (12) and a cover (30) attached to the case. The cover (30) is formed of a first material and has an outer surface (41) and an inner surface (42) defining a thickness thereof. The cover (30) also has a fluid fill hole (34) formed therein. The fluid fill hole (34) has an outer diameter (44) at the outer surface and a smaller inner diameter (45) at the inner surface. A hermetic seal (62) is formed within the fluid fill hole (34) of a second material that is softer than the first material and that is deformed to assume the approximate shape of the fluid fill hole (34).
