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.

Feb 17, 2010
Appl. No.:

12/707252
Inventors:

John M. Edgell - Plymouth MN, US
Lawrence D. Swanson - White Bear Lake MN, US
John E. Hanson - Ham Lake MN, US
Abhi V. Chavan - Maple Grove MN, US
Assignee:

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

A61B 17/00
B25B 23/142
US Classification:

606 1, 81478
Abstract:

Embodiments of the invention are related to tools for coupling leads to header assemblies for implantable medical devices, amongst other things. A wrench is configured so that if an axial force exceeding a first threshold is applied to a handle housing, then the housing handle will rotate with respect to a shaft. Other embodiments are also included herein.

US Patent:

8612003, Dec 17, 2013
Filed:

Feb 16, 2011
Appl. No.:

13/028532
Inventors:

Lawrence D. Swanson - White Bear Lake MN, US
John M. Edgell - Plymouth MN, US
John E. Hansen - Ham Lake MN, US
Assignee:

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

A61N 1/375
US Classification:

607 36
Abstract:

The present subject matter provides feedthrough or interconnect systems for components of an implantable medical device and methods for their manufacture. A feedthrough system includes a wire or nailhead having a protruded tip. The wire or nailhead extends from an aperture in an encasement of a first component and is connected to a terminal conductor adapted to electrically connect to circuitry within the encasement. A ribbon wire has a distal end adapted to electrically connect to a second component and a proximal end having a pattern adapted to fit to the protruded tip of the wire or nailhead to provide for subsequent attachment of the ribbon wire to the nailhead.

US Patent:

20070213781, Sep 13, 2007
Filed:

Mar 10, 2006
Appl. No.:

11/276699
Inventors:

Benjamin Fruland - Plymouth MN, US
Larry Hum - Cottage Grove MN, US
Lawrence Swanson - White Bear Lake MN, US
International Classification:

A61N 1/00
US Classification:

607037000
Abstract:

A body implantable retaining assembly for forming an electrical or mechanical connection between a medical device and a lead is discussed herein. A first bore is formed in a housing of the device for receiving a lead terminal portion. A second bore is also formed in the device housing, which opens to the first bore and to an exterior housing surface. A retaining assembly is mounted within the second bore and is positioned to align with a lead terminal pin or a lead terminal ring. The retaining assembly is adjustable by an instrument, thereby allowing engagement and securing of the lead and the housing. A seal member provides electrical and fluid isolation of the retaining assembly from bodily fluids located proximate to the housing exterior surface. The seal member is disposed in the second bore between the retaining means and the exterior housing surface and includes a lubricated passage therethrough.
