Abstract

An implantable device is described that collects and aggregates data from non-implanted medical devices external from a body of a patient. The device may also collect and aggregate data from medical devices implanted within the body. The implantable device includes a wireless transceiver to acquire physiological data from the external medical devices, and a storage medium to store the physiological data. A processor retrieves the physiological data and communicates the physiological data to a remote patient management system. The device may collect the physiologic data from the various external data sources, possibly over an extended period of time, and stores the data for subsequent upload to a common patient management system. In addition, the implantable device may collect physiological data from other medical devices implanted within the patient. In this manner, the device provides a central point for collection and aggregation of physiological data relating to the patient.

Claims

8. The method of claim 1, wherein communicating the aggregated physiological data to the remote system comprises establishing a network communication session between the implantable medical device and a wireless access point.

9. The method of claim 1, further comprising:

receiving additional physiological data from a medical device implanted within the body of the patient; and

aggregating the additional physiological data received from the implanted medical device with the physiological data received from the external medical devices for communication to the remote system.

10. The method of claim 1, wherein communicating the aggregated physiological data from the implanted device to a remote system comprises:

detecting an activation signal;

detecting an communication interface of the remote system in response to the activation signal; and

retrieving the aggregated physiological data from a computer-readable medium within the implanted device; and

communicating the aggregated physiological data to the upload device for communication to the remote system.

11. The method of claim 10, wherein detecting the communication interface comprises attempting to initiate a communication session with the communication interface in accordance with a wireless communication device in response to the activation signal.
