Abstract: The present technology is directed to implantable medical devices comprising an electrical circuit for powering one or more active components of the device, such as an actuation element, an engine, or a sensor. The electrical circuit can include one or more inductors having a plurality of receiving coils that generate a current in response to being exposed to an electromagnetic field. The current generated by the receiving coils can be used to directly or indirectly power the one or more active components. The inductors can have one or more wires having a non-concentric configuration such that, in addition to generating the current for powering the device, the receiving coils also anchor a portion of the device when it is implanted. For example, the receiving coils can be at least partially composed of a superelastic material such that they exhibit superelastic properties at body temperature.

Abstract: Embodiments of the present invention generally provide an anastomosis device that can be used to couple two or more layers of tissue in apposition. In an exemplary embodiment, the device can be formed from one or more woven wires that can be configured to have a generally tubular shape in a first, expanded position for insertion to an anastomosis site and a generally annular, ring-shape in a second, resting position for securing tissue in apposition at the anastomosis site. The device can be adapted either to cause necrosis of the tissue layers around an outer periphery of the device or to promote growth of tissue about an inner periphery of the device.
