News editors obtained the following quote from the background information supplied by the inventors: "The present invention relates to communication with implantable medical devices. Medical devices, such as cardiac pacemakers and implantable pulse generators of spinal cord stimulation systems are implanted beneath the skin of a human body. Occasionally, these implanted devices receive messages from or send data to an external device. Such messages can include, for example, receiving updated control parameters or sending operational history data that can then be analyzed by the external system."
As a supplement to the background information on this patent application, VerticalNews correspondents also obtained the inventors' summary information for this patent application: "When several implantable medical devices utilize the same wireless communication protocol to communicate with external devices, it is possible that an implanted medical device will send messages to or receive messages from the wrong external device. For example, if two or more patients with the same implant are in the same location at a hospital or support group meeting, a command sent by one patient through an external controller for his implanted medical device might be received and processed by another patient's implanted medical device.
"In one embodiment, the invention provides a method of identifying an external device that sent a message and then determining whether to process the message based in part on the identity of the external device that sent the message. The implanted device receives a message from the external device and identifies an external device ID in the received message. The external device ID identifies the external device that sent the message. The implanted device then compares the external device ID from the message to a stored list of approved external device IDs. The implanted device processes the message when the external device ID matches one of the approved external device IDs in the stored list of approved external device IDs. However, the message is disregarded when the external device ID does not match any of the approved external device IDs in the stored list of approved external device IDs. In some embodiments, the implanted device returns an error message to the external device when the external device ID does not match any of the approved external device IDs in the stored list.
"In some embodiments, the implanted medical device processes all messages received from a clinical control device and only processes messages sent from external devices other than clinical control devices when the external device ID matches one of the approved external device IDs in the stored list of approved external device IDs. The implanted medical device determines whether the external device that sent the message is a clinical control device by comparing the external device ID to a range of external device IDs reserved for clinical control devices. A clinical control device can send instructions to the implanted medical device adding or removing external device IDs to the stored list of approved external device IDs.
