  • Publication number: 20200094063
    Abstract: Systems, methods and implantable devices configured to provide cardiac resynchronization therapy and/or bradycardia pacing therapy. A first device located in the heart of the patient is configured to receive a communication from a second device and deliver a pacing therapy in response to or in accordance with the received communication. A second device located elsewhere is configured to determine an atrial event has occurred and communicate to the first device to trigger the pacing therapy. The second device may be configured for sensing the atrial event by the use of vector selection and atrial event windowing, among other enhancements. Exception cases are discussed and handled as well.

  • Patent number: 10556119
    Abstract: An implantable pulse generator includes a device housing containing pulse generator circuitry and a header connected to the device housing. The header includes a core assembly defining first and second lead bore cavities sized for receiving terminal pins of leads, first and second labels, and an outer layer. The first label is printed onto a surface of the core assembly proximate the first lead bore cavity and includes a first color. The second label is printed onto the surface of the core assembly proximate the second lead bore cavity and includes a second color different from the first color. The outer layer is overmolded over the core assembly so as to encapsulate the first and second labels and to allow access to the first and second lead bore cavities.

  • Publication number: 20190054304
    Abstract: An implantable medical device (IMD) is configured with a pressure sensor. The IMD includes a housing and a diaphragm that is exposed to the environment outside of the housing. The diaphragm is configured to transmit a pressure from the environment outside of the housing to a piezoelectric membrane. In response, the piezoelectric membrane generates a voltage and/or a current, which is representative of a pressure change applied to the housing diaphragm. In some cases, only changes in pressure over time are used, not absolute or gauge pressures.
