Patent number: 8401648Abstract: An implantable medical device includes a housing having frame with one or more openings. The openings of the frame are covered with a thin metallic foil that is welded to the frame to provide a hermetic seal. Non-conductive members may be placed in or about the openings to provide a backing or structural support for the metallic foil. By decreasing the mass of conductive material capable of forming eddy currents, improved recharge or telemetry performance may be realized.Type: GrantFiled: August 6, 2008Date of Patent: March 19, 2013Assignee: Medtronic, Inc.Inventors: John E.
