The device includes radio frequency (RF) communication components installed within a case of the device and an antenna with an inverted E shape mounted within a header of the device. The antenna has three branches extending from a main horizontal arm: a capacitive branch connecting one end of the main arm to the case via a capacitive load; an RF signal feed branch connecting a middle portion of the main arm to the internal RF components of the device via a feedthrough; and an inductive branch connecting the opposing (far) end of the main arm to the case to provide a shunt to ground. The E-shaped configuration and the provision of capacitive loading allows for cancellation of inductance to bring the antenna into resonance and to provide optimal radiation efficiency as well as to provide for impedance with no reactive component.

An implantable medical device including a can, a feedthrough and an antenna assembly. The can includes a lead connector assembly, electronics, and a metal wall defining a hermetic sealed compartment. The electronics and lead connector assembly are located in the hermetic sealed compartment. The feedthrough extends through the metal wall between the hermetic sealed compartment and exterior the metal wall. The antenna assembly includes an antenna extending along the metal wall in a spaced-apart manner from the metal wall and encased in a dielectric material. The dielectric material occupies a space between the antenna and the metal wall. The antenna is electrically connected to the electronics via an RF conductor of the feedthrough.

A biostimulator, such as a leadless cardiac pacemaker, having a patch antenna integrated into a housing, is described. The housing includes an annular wall that contains electronic circuitry of the biostimulator and provides a ground plane of the antenna. The patch antenna includes a meandering trace embedded in a curved dielectric layer that is mounted on the annular wall. The trace provides a conductor of the antenna and the dielectric layer provides a dielectric substrate of the antenna between the conductor and the ground plane. The electronic circuitry contained within the annular wall is electrically connected to the trace via an electrical feedthrough that passes through the annular wall and the dielectric layer. The electrical feedthrough places the electronic circuitry in communication with the antenna to transmit or receive wireless communication signals from an external device. Other embodiments are also described and claimed.

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.
