US Patent:

6879857, Apr 12, 2005
Filed:

Sep 6, 2002
Appl. No.:

10/236628
Inventors:

Lawrence Swanson - Lino Lakes MN, US
Nick Youker - River Falls WI, US
Stephen VanDerlick - Andover MN, US
Assignee:

Cardiac Pacemakers, Inc. - St. Paul MN
International Classification:

A61N001/375
US Classification:

607 36, 607 37
Abstract:

A method of fabricating implantable electronic medical devices eliminates the use of a backfill tube on the header or feed-through by reconfiguring the device's lead connector block anchor so as to provide it with a plug that can be used to seal an aperture in the device's header following removal of undesirable welding gases and replacement with an inert gas with a high breakdown resistance.

Appl. No.:

10/632138
Inventors:

Nick A. Youker - River Falls WI, US
Lawrence D. Swanson - Lino Lakes MN, US
John E. Hansen - Coon Rapids MN, US
William J. Linder - Golden Valley MN, US
Assignee:

Cardiac Pacemakers, Inc. - St. Paul MN
International Classification:

H05K 7/02

H05K 7/08
H05K 7/10
US Classification:

361782, 361763, 361794
Abstract:

An assembly integrating commercially available capacitors into filtered feedthroughs. A feedthrough assembly comprises a plurality of Input/Output (I/O) conductors, wherein the I/O conductors pass through a hermetic seal such that a first end of the I/O conductors reside on a non-hermetic side of the hermetic seal and a second end of the I/O conductors reside on a hermetic side of the hermetic seal, a printed circuit interconnect substrate residing on the hermetic side of the hermetic seal, and a plurality of ceramic chip capacitors mounted on the printed circuit interconnect substrate, wherein a first end of each capacitor is connected via the interconnect to the second end of an I/O conductor and a second end of each capacitor is connected via the interconnect to a constant voltage level.
