摘要:
Systems and methods for communicating with an implant within a patient's body using acoustic telemetry includes an external communications device attachable to the patient's skin. The device includes an acoustic transducer for transmitting acoustic signals into the patient's body and/or for receiving acoustic signals from the implant. The device includes a battery for providing electrical energy to operate the device, a processor for extracting data from acoustic signals received from the implant, and memory for storing data. The device may include an interface for communicating with a recorder or computer, e.g, to transfer data from the implant and/or to receive instructions for controlling the implant. The device is secured to the patient's skin for controlling, monitoring, or otherwise communicating with the implant, while allowing the patient to remain mobile.

A medical system includes implantable devices and an external device configured for wirelessly interacting with the implantable devices. The external device may be attachable to a patient and be configured for wirelessly communicating with a first implantable device, e.g., using acoustic energy, and wirelessly interacting with a second implantable device, e.g., using non-acoustic energy. The first implantable device may be a diagnostic device, in which case, the external device may wirelessly receive physiological information from the diagnostic device, and the second implantable device may be a therapeutic device, in which case, the external device may wirelessly interact with the therapeutic device to provide or optimize therapy to a patient

An implant for insertion or implantation within a body includes an electrical circuit for performing one or more commands when the implant is activated, an energy storage device, and a switch coupled to the electrical circuit and the energy storage device. An acoustic transducer is coupled to the switch, the acoustic transducer being activatable upon acoustic excitation by an external acoustic energy source for closing the switch to allow current flow from the energy storage device to the electrical circuit. The one or more commands includes measuring a physiological parameter with a biosensor coupled to the electrical circuit, or controlling a therapeutic device coupled to the electrical circuit. The therapeutic device or biosensor may be activated for a predetermined time or until the switch is opened in response to another acoustic excitation of the acoustic transducer.

A system for measuring pressure in the body comprising an implanted device for detecting internal absolute pressure, an external monitor providing barometric (atmospheric) pressure, an acoustic or radio telemetric system and a global positioning system (GPS). The barometric pressure is retrieved from a remote source such as an Internet weather web site or a database containing real-time barometric pressure data for various locations in the world by using the GPS data. The gauge pressure is then derived by subtracting the barometric pressure from the absolute pressure.
