  • Patent number: 9724784
    Abstract: In general, the disclosure is directed toward transmitting radiant energy across a boundary of a medical device via an optical feedthrough. A system for transmitting radiant energy across a boundary of a medical device includes a first functional module of a medical device, a second functional module of the medical device, an optical feedthrough assembly coupled to the first functional module, and a radiant energy source that emits a beam through the optical feedthrough assembly to perform a manufacturing process on the first functional module and the second functional module.
    Type: Grant
    Filed: March 10, 2009
    Date of Patent: August 8, 2017
    Assignee: Medtronic, Inc.
    Inventors: Reginald D. Robinson, David D. Differding, James A. Johnson, Bernard Q. Li, Gerald G. Lindner, Brad C. Tischendorf, Andrew J. Thom
  • Patent number: 8903473
    Abstract: A radiopaque marker for inclusion within an implantable medical device (IMD) may comprise one or more radiopaque articles selected from a predetermined set of radiopaque articles. The one or more radiopaque articles may be carried by an object formed of or including, a desiccant. The predetermined set of radiopaque articles may undergo a single qualification process that approves the use of any combination of one or more of the articles as a radiopaque marker within an IMD. This allows a potentially-limitless number of markers to be made available based on a single qualification process. The radiopaque marker may serve to provide information such as the make, model, and feature set of the device.

  • Patent number: 8192418
    Abstract: In general, the disclosure is directed toward releasing material within a medical device via an optical feedthrough. A system for releasing material with a medical device comprises a cup that holds a material, wherein the cup includes a discharge port, a seal disc that seals the material within the cup, an optical feedthrough assembly coupled to the cup, a shell that defines a chamber within a medical device, wherein the optical feedthrough assembly is coupled to the shell, and a radiant energy source that shines a beam through the optical feedthrough assembly to puncture the seal disc to allow the material to enter the chamber via the discharge port.
