1. An implant for surgical insertion, implantation, or location within a body, comprising:

  • a pressure sensor for measuring intra-body pressure;

    a controller coupled to the pressure sensor for acquiring pressure data from the pressure sensor;

    one or more acoustic transducers for converting energy between electrical energy and acoustic energy, the one or more acoustic transducers configured for at least one of converting acoustic energy from a source external to the implant into electrical energy and transmitting an acoustic signal comprising the pressure data to a location external to the implant; and

    an energy storage device coupled to at least one of the one or more acoustic transducers, the energy storage device configured for storing electrical energy converted by the one or more acoustic transducers, the energy storage device coupled to the controller for providing electrical energy to support operation of the implant.
