  • Feedthrough assembly for an implantable medical device
    Patent number: 9643020
    Abstract: Processes for manufacture and assembly of implantable medical devices are described. In particular, techniques are provided for nondestructive electrical isolation assessment of feedthrough assemblies of the implantable medical devices. The feedthrough assemblies may include an insulating structure, a plurality of terminal pins extending through the insulator and a ferrule having an inner lumen into which the insulating structure is disposed. One or more insulating seals may be disposed at the interface of the ferrule-to-insulating structure and/or the terminal pin-to-insulating structure. The electrical isolation assessments may be based on the dielectric properties of the components of the feedthrough assemblies, such as the insulating structure.
    Type: Grant
    Filed: August 9, 2013
    Date of Patent: May 9, 2017
    Assignee: Medtronic, Inc.
    Inventors: Simon E. Goldman, Rajesh V. Iyer, Curtis E. Burgardt, Zhi Fang, Michael J. Galloway, Ryan J. Jensen, James A. Martin, Fabian A. Pena

  • Determination of equivalent series resistance
    Patent number: 7816928
    Abstract: A determination of an equivalent series resistance (ESR) effect for high frequency filtering performance of a filtered feed-through assembly is described. A low frequency signal is introduced to a filtered feed-through assembly. ESR limit of the filtered feed-through is determined based on the low frequency signal.
