Abstract

An implantable restriction device is configured to provide a restriction in a patient as a function of the pressure of fluid. The implantable restriction device includes one or more pressure sensors configured to sense pressure of the fluid within the implantable restriction device. Pressure data obtained by the one or more pressure sensors may be communicated to a device located external to the patient, such as a data logger, using telemetry coils or other communicators. The data logger may store the pressure data, and may communicate the pressure data to a remote location via a network such as the Internet. A docking station may be provided to couple the data logger to a network and/or to recharge a cell in the data logger.

Claims

(d) one or more external communicators in communication with the one or more implantable communicators, wherein the one or more external communicators are operable to externally receive data communicated from within a patient by the one or more implantable communicators; and

(e) a storage device in communication with the one or more external communicators, wherein the storage device is operable to store at least a portion of data received by the one or more external communicators.

2. The system of claim 1, wherein the implantable restriction forming device comprises an adjustable gastric band.

3. The system of claim 1, wherein the implantable restriction forming device comprises an injection port configured to receive fluid.

4. The system of claim 3, wherein the implantable pressure sensor is located within the injection port.

5. The system of claim 1, wherein one or both of the one or more implantable communicators or the one or more external communicators comprise at least one coil.

6. The system of claim 1, further comprising a data logger in communication with the one or more external communicators, wherein the storage device is located within the data logger, wherein the data logger is operable to provide a source of energy to the one or more external communicators.

7. The system of claim 6, further comprising a sense head, wherein the one or more external communicators are located within the sense head.

8. The system of claim 7, wherein the data logger and the sense head are located in separate housings connected via a cable.

9. The system of claim 6, wherein the data logger comprises a rechargeable cell, wherein the rechargeable cell is configured to provide power to the one or more external communicators.

10. The system of claim 9, further comprising a docking station, wherein the data logger is configured to selectively couple with the docking station, wherein the docking station is configured to recharge the rechargeable cell.

11. The system of claim 10, wherein the docking station further comprises a communication port in communication with the storage device, wherein the communication port is configured to communicate with a network.

12. The system of claim 1, further comprising a communication port in communication with the storage device, wherein the communication port is configured to communicate with a network.

13. A system for obtaining data from an implanted device, the system comprising:
