Publication number: 20160317806Abstract: A method of manufacturing an implantable medical device having reduced MRI image distortion, includes producing an implantable medical device. The implantable medical device has a configuration that comprises a housing and one or more internal components disposed within the housing. The configuration is based upon a design process that includes creating a first prototype, determining the aggregate relative magnetic permeability of the first prototype, and modifying the design of the first prototype by at least one of (a) selecting and adding a diamagnetic shimming material to the first prototype or (b) repositioning one or more internal components of the first prototype. Modifying the design results in a modified design that is the configuration for the implantable medical device.Type: ApplicationFiled: June 17, 2016Publication date: November 3, 2016Applicant: Medtronic, Inc.Inventors: John Kast, Carl D. Wahlstrand, Mark J. Conroy, Erik R. Scott

Patent number: 7798862Abstract: An electrical connection assembly of a medical device includes a plurality of electrical contact blocks and a sealing member, which are held within a cavity of a base of the assembly. The sealing member includes a plurality of openings, at least one interior surface surrounding a bore and at least one void. Each electrical contact block extends into a corresponding opening of the sealing member, and a conductive sidewall of each block defines a portion of a perimeter of an area for receiving a lead connector, while the bore of the sealing member forms another portion of the perimeter of the area. The at least one void provides a compressible space in a bulk volume of the sealing member. When the lead is inserted within the area, and a cap is engaged with the base, the at least one interior surface of the sealing member is compressed about the lead.Type: GrantFiled: June 10, 2009Date of Patent: September 21, 2010Assignee: Medtronic, Inc.Inventors: John Kast, Mark Lent, James Olsen, Andrew Ries, James Skakoon, Carl Wahlstrand
