Abstract

Device data is generated at each medical device in a system including a plurality of medical devices. Priority information is dynamically assigned to the device data at each medical device based on the character of the device data. The device data and the priority information are transmitted from each medical device. Interfering communications of device data and priority information from multiple medical devices are processed successively based on the priority information.

Claims

1. A method for prioritizing communications from a plurality of implanted medical devices to a processing unit, at least two of the plurality of implanted medical devices being subcutaneously implanted in different patients, the method comprising:

automatically generating device data from subcutaneously implanted sensors at each implanted medical device;

dynamically assigning priority information to the device data at each implanted medical device based on a character of the device data;

then

communicating the device data and the priority information from each implanted medical device to the processing unit; and

processing, with the processing unit, simultaneous interfering communications of device data and priority information from the plurality of implanted medical devices based on the priority information.

2. The method of claim 1, wherein dynamically assigning priority information to the device data at each implanted medical device based on a character of the device data comprises:

dynamically assigning priority information to the device data based on an urgency of the device data generated.

3. The method of claim 1, wherein communicating the device data and the priority information from each implanted medical device comprises:

interrogating each implanted medical device for the device data; and

transmitting the device data and the priority information.

4. The method of claim 3, wherein the device data and the priority information are transmitted in a common communication platform.

5. The method of claim 1, wherein processing simultaneous interfering communications of device data and priority information from the plurality of implanted medical devices based on the priority information comprises:

temporarily suspending processing of lower priority interfering communications; and

processing a highest priority interfering communication.

6. The method of claim 5, wherein processing simultaneous interfering communications of device data and priority information from the plurality of implanted medical devices based on the priority information further comprises:

processing a next highest priority interfering communication subsequent to processing of the highest priority interfering communication.

7. In a system comprising a plurality of implanted medical devices and a processing unit, wherein a first of the plurality of implanted medical devices is subcutaneously implanted in a first patient and a second of the plurality of implanted medical devices is subcutaneously implanted in either the first patient or a second patient, and wherein each of the plurality of implanted medical devices is operable to communicate device data, wherein each implanted medical device generates the device data and dynamically assigns a priority level to the device data based on a classification of the device data, a method of coordinating interfering communications of device data between multiple implanted medical devices, the method comprising:

comparing the relative priority levels assigned to the device data in each of the interfering communications with the processing unit; and

processing each of the interfering communications with the processing unit based on the respective priority levels assigned to the device data in each of the interfering communications.

8. The method of claim 7, wherein processing each of the interfering communications in an order based on the respective priority levels assigned to the device data in each of the interfering communications comprises:

temporarily suspending processing of interfering communications with lower priority levels; and

processing an interfering communication with a highest priority level.

9. The method of claim 8, wherein processing each of the interfering communications in an order based on the respective priority levels assigned to the device data in each of the interfering communications further comprises:

processing an interfering communication with a next highest priority level subsequent to processing the interfering communication with the highest priority level.

10. The method of claim 7, wherein the classification of the device data is based on an urgency of the device data being transmitted.

11. The method of claim 7, wherein the classification of the device data is based on a priority classification structure stored in the implanted medical device.

12. A system comprising:

a plurality of medical devices a first one of which is configured to be implanted in a first patient and a second one of which is configured to be implanted in a second patient different from the first patient, each of the plurality of medical devices having implanted sensors and being operable to automatically generate and transmit device data and priority information about the device data, the priority information being dynamically updated at each medical device based on a character of the device data being transmitted; and

a processing unit operable to receive the device data and priority information, wherein the processing unit processes interfering transmissions from the plurality of medical devices based on the priority information of the interfering transmissions.

13. The system of claim 12, wherein the character of the device data is based on an urgency of the device data being transmitted.

14. The system of claim 12, wherein the character of the device data is based on a priority classification structure stored in each medical device.
