  • Patent number: 11786125
    Abstract: An implantable device includes a substrate and protective cover that cooperate to define an enclosed sensor volume. A sealed enclosure is provided within the sensor volume, with an electronic component assembly (ECA) being located within the sealed enclosure. A flexible circuit board assembly (FCBA) is electrically coupled with the ECA through a wall of the sealed enclosure. At least one transducer is provided on the FCBA in contact with the substrate, and the FCBA is held apart from the enclosure via a polymeric spacer provided therebetween. An inert polymer fill is provided within the sensor volume external to the enclosure.

  • Publication number: 20210128331
    Abstract: A stent is placed inside an aorta of a subject, the stent comprising one or more electrodes, control circuitry, and a first antenna coupled thereto. A second antenna circumscribes a neck of the subject, such that that at least one turn of wire of the second antenna extends from a first position that is anatomically superior to a left clavicle of the subject to a second position that is anatomically inferior to a jugular notch of the subject and from the second position to a third position that is anatomically superior to a right clavicle of the subject. The second antenna transmits an electrical signal to the first antenna via inductive coupling, and is shaped to have an L-shaped projection in a sagittal plane, with an angle between two legs of the L-shaped projection being 80-160 degrees when placed upon a flat surface. Other applications are also described.
