US Classification:

429181, 429 94, 429175, 429176

Abstract:

A battery having an electrode assembly located in a housing that efficiently utilizes the space available in many implantable medical devices is disclosed. The battery housing provides a cover and a shallow case a planar bottom, an open top to receive the cover, and a plurality of sides being radiused at intersections with each other and with the bottom to allow for the close abutting of other components located within the implantable device while also providing for efficient location of the battery within an arcuate edge of the device.

B23K 31/02

US Classification:

429163, 429 80, 2281246

Abstract:

An electrochemical cell, comprising: an encasement including a case having a bottom and a sidewall terminating at an open top and a cover disposed over the case open top and hermetically sealed to the case, the encasement defining an interior space for containing cell components; and an access port defining at least one lumen extending through any of the case bottom, the case sidewall or the cover for receiving a liquid electrolyte, the access port being sealed closed after receiving the liquid electrolyte using a fusion welding method in the presence of the electrolyte.

Assignee:

Medtronic, Inc. - Minneapolis MN

International Classification:

H01M 2/02

US Classification:

429 80

Abstract:

An electrochemical cell () suitable for use in an implantable medical device () includes a case () and a cover () attached to the case. The cover () is formed of a first material and has an outer surface () and an inner surface () defining a thickness thereof. The cover () also has a fluid fill hole () formed therein. The fluid fill hole () has an outer diameter () at the outer surface and a smaller inner diameter () at the inner surface. A hermetic seal () is formed within the fluid fill hole () 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 ().

Abstract:

A battery having an electrode assembly located in a housing that efficiently utilizes the space available in many implantable medical devices is disclosed. The battery housing provides a cover and a shallow case a preferably planar, major bottom portion, an open top to receive the cover opposing the bottom portion, and a plurality of sides being radiused at intersections with each other and with the bottom to allow for the close abutting of other components located within the implantable device while also providing for efficient location of the battery within an arcuate edge of the device. The cover and the shallow case being substantially hermetically sealed by a laser weld technique and an insulator member disposed within the case to provide a barrier to incident laser radiation so that during welding radiation does not impinge upon radiation sensitive component(s) disposed within the case.
