  • Patent number: 11818654
    Abstract: A method for managing power during communication with an implantable medical device, including establishing a communications link, utilizing a power corresponding to a session start power, to initiate a current session between an implantable medical device (IMD) and external device. A telemetry break condition of the communications link is monitored during the current session. The power utilized by the IMD is adjusted between low and high power levels, during the current session based on the telemetry break condition. The number of sessions is counted, including the current session and one or more prior sessions, in which the IMD utilized the higher power level, and a level for the session start power to be utilized to initiate a next session following the current session is adaptively learned based on the counting of the number of sessions.

  • Patent number: 11776684
    Abstract: A medical device and method are provided. The medical device includes a battery, a charge bank configured to store supplemental energy, memory to store program instructions, and device operational circuitry. The device operational circuitry identifies an energy demand (ED) action to be performed by the device operational circuitry in connection with at least one of monitoring a medical characteristic of interest (COI), treating the medical COI, or wirelessly communicating with a separate device. The device operational circuitry obtains an energy consumption estimate for an amount of energy to be consumed by the device operational circuitry in connection with performing the ED action and dispatches a charge instruction to charge the charge bank from the battery with supplemental energy. The device operational circuitry supplies the supplemental energy to the device operational circuitry for performing the ED action in connection with the at least one of monitoring, treating or communicating operations.

  • Publication number: 20230302285
    Abstract: A biostimulator, such as a leadless pacemaker, including a header assembly having an electrical feedthrough assembly incorporating a helix mount, is described. The header assembly includes a fixation element mounted on the helix mount. The helix mount is mounted on a flange of the electrical feedthrough assembly, and thus, the fixation element can attach the leadless biostimulator to a target tissue. An electrode of the electrical feedthrough assembly is mounted within the flange to deliver a pacing impulse to the target tissue. A ceramic portion of the helix mount is disposed between the flange and the electrode to block an electrical path between the electrode and the flange. Accordingly, the helix mount both retains the fixation element on the leadless biostimulator and electrically isolates the flange and electrode components of the electrical feedthrough. Other embodiments are also described and claimed.

  • Publication number: 20230261368
    Abstract: Methods for manufacturing implantable electronic devices include forming an antenna of the implantable electronic device by delivering an antenna trace within a dielectric antenna body. The antenna trace includes a first trace portion disposed in a first transverse layer and defining a first trace path and a second trace portion disposed in a second transverse layer longitudinally offset from the first transverse layer and defining a second trace path. If projected to be coplanar, the first trace path defines a trace boundary and the second trace path is within the trace boundary.
