Methods, systems, and apparatus for recharging medical devices implanted within the body are disclosed. An illustrative method of recharging an implanted medical device includes delivering a charging device to a location adjacent to the implanted medical device, activating a charging element coupled to the charging device and transmitting charging energy to a receiver of the implanted medical device, and charging the implanted medical device using the transmitted charging energy from the charging device.

An implantable stimulation system comprises an implantable stimulator and a control device. The control device is configured to transmit acoustic waves to the implantable stimulator, and the implantable stimulator is configured to transform the acoustic waves into electrical current, and generate stimulation energy based on the electrical current. For example, the electrical current can be transformed into electrical energy that can be used to generate the stimulation energy. Or the electrical current can contain signals used to directly or indirectly control the generation of the stimulation energy.

Acoustically powered implantable stimulating device

Systems and methods provide intrabody communication using acoustic telemetry. The system includes a first or control implant including a first acoustic transducer, and a second implant including a switch and a second acoustic transducer coupled to the switch. The second acoustic transducer receives acoustic signals from the first acoustic transducer for closing the switch to activate the second implant. The second implant may include a sensor for measuring a physiological parameter that is transmitted using acoustic signals including the physiological data to the first implant. For example, the second implant may measure pressure in the patient's heart that may be used by the first implant to control a pacemaker. Alternatively, the second implant may blood sugar concentration that may be used by the first implant to control an insulin pump. Alternatively, the first implant may store and transfer the data to an external device for monitoring the patient.

A device and method are provided for spontaneous electrochemical production of therapeutic species, in vivo. An active metal is implanted in the tissue. The metal undergoes corrosion, thus acting as a reducing agent to constituents in the tissue, so as to cause these constituents to form the therapeutic agents.

An implant includes a pressure sensor, a controller for acquiring pressure data from the sensor, and an acoustic transducer for converting energy between electrical energy and acoustic energy. A capacitor is coupled to the acoustic transducer for storing electrical energy converted by the transducer and/or for providing electrical energy to operate the implant. The acoustic transducer may operate alternatively or simultaneously as an energy exchanger or an acoustic transmitter. During use, the implant is implanted within a patient's body, and an external transducer transmits a first acoustic signal into the patient's body, to energize the capacitor. The implant then obtains pressure data, and transmits a second acoustic signal to the external transducer, the second acoustic signal including the pressure data.

Implantable pressure sensors and methods for making and using them

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 the 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.

Systems and methods for communicating with implantable devices

The invention includes systems and methods for converting absolute pressure data acquired in anatomical environments to gauge pressure data using an implant configured to monitor pressure. The implant is configured to communicate with an external controller, which is configured to communicate with a remote microprocessor that includes real-time barometric pressure data for one or more geographic locations.

Barometric pressure correction based on remote sources of information

A device for controlled release of molecules is provided. The device including: (a) a device body having at least one reservoir therein for containing the molecules, the at least one reservoir being formed with a barrier impermeable to the molecules thereby preventing release thereof from the at least one reservoir; and (b) at least one acoustic transducer being attached to, or forming a part of, the device body, the at least one acoustic transducer being for converting an acoustic signal received thereby into an electrical signal, the electrical signal leading to barrier permeabilization and therefore release of the molecules from the at least one reservoir.

A stent graft includes a tubular prosthetic graft, a support structure expandable between contracted and enlarged conditions, and a biosensor attached thereto. The biosensor may be directly attached to an outer surface of the graft, to struts defining the support structure, or by one or more filaments configured to dispose the biosensor beyond an outer surface of the stent graft. When the biosensor is attached by one or more filaments, the stent graft is mounted in a contracted profile on a delivery apparatus with the biosensor disposed adjacent to the stent graft thereon. The stent graft is introduced into a blood vessel in the contracted profile, and advanced endolumenally until it is positioned across an aneurysm. The stent graft is expanded towards an enlarged profile such that ends of the stent graft engage healthy regions of the vessel adjacent to the aneurysm, thereby isolating the aneurysm from the rest of the vessel with the biosensor disposed within the aneurysmal sac, the biosensor allowing remote monitoring of pressure or other conditions to detect an endoleak or excessive pressure therein.
