Abstract

A communicator facilitates communications with a remote server via a wireless network supporting a plurality of disparate data transport mechanisms having differing characteristics. A processor coupled to memory is disposed in a communicator housing, which is configured for portability. The memory stores wireless radio firmware and data transfer instructions that are executable by the processor for transferring data to the remote server in accordance with a priority level. The priority level is based in part on criticality of the data and the communicator status. A radio disposed in the housing effects communications via the wireless network in accordance with the firmware. A power source in the housing supplies power for communicator components. The processor executes program instructions for selecting a data transport mechanism among the plurality transport mechanisms based on the priority level, and transmits the data via the wireless network via the radio using the selected transport mechanism.

Claims

1. A communicator configured to facilitate communications with a remote server via a wireless network, the wireless network supporting a plurality of disparate data transport mechanisms having differing characteristics, the communicator comprising:

a housing configured for portability by an ambulatory patient;

a processor coupled to memory, the processor and the memory disposed in the housing, the memory storing wireless radio firmware and data transfer instructions, the data transfer instructions executable by the processor for transferring data to the remote server in accordance with a priority level, wherein the priority level is based at least in part on criticality of the data and the communicator status;

a radio disposed in the housing and configured to effect communications via the wireless network in accordance with program instructions of the wireless radio firmware executable by the processor; and

a power source provided in the housing and configured to supply power for components of the communicator;

the processor configured to execute program instructions for selecting a data transport mechanism among the plurality of disparate data transport mechanisms based at least in part on the priority level and transmitting the data via the wireless network to the remote server using the selected transport mechanism via the radio.

2. The communicator of claim 1, wherein the communicator status comprises an infrastructural status of the communicator defining one or more data transport mechanisms available to it among the plurality of disparate data transport mechanisms.

3. The communicator of claim 1, wherein the communicator is configured to receive the criticality of the data from a medical device.

4. The communicator of claim 1, wherein the data comprises clinician requested data.

5. The communicator of claim 1, wherein the data comprises specified patient data.

6. The communicator of claim 1, wherein the data comprises specified clinical event data.

7. The communicator of claim 1, wherein the data comprises specified arrhythmia data.

8. The communicator of claim 1, wherein the data comprises specified episode data.

9. The communicator of claim 1, wherein the communicator is configured to establish communications with a medical device, connect with the remote server, and determine if data is to be acquired from the medical device prior to establishing communications with the medical device.

10. The communicator of claim 1 configured to receive pushed data from a medical device;

and

the communicator is configured to connect with the remote server in response to receiving the pushed data.

11. The communicator of claim 1, wherein the communicator is configured to transmit portions of the data at different times based on priority levels associated with each portion of the data.

12. A communicator for facilitating communications with a remote server via a wireless network, the wireless network supporting a plurality of disparate data transport mechanisms having differing characteristics, the communicator comprising:

a housing configured for portability by an ambulatory patient;

a processor coupled to memory, the processor and the memory disposed in the housing, the memory storing wireless radio firmware;

a radio provided in the housing and configured to effect communications via the wireless network in accordance with program instructions of the wireless radio firmware executable by the processor; and

a power source provided in the housing and configured to supply power for components of the communicator;

the processor configured to receive first data to which a first priority level is assigned, wherein the first priority level is based at least in part on criticality of the first data and the communicator status, the processor further configured to execute program instructions for selecting a first data transport mechanism among the plurality of disparate data transport mechanisms based at least in part on the first priority level, and transmitting the first data via the wireless network using the first transport mechanism via the radio.

13. The communicator of claim 12, wherein the processor is further configured to retransmit the first data via the wireless network if it is determined that the previously transmitted data was not received.

14. The communicator of claim 12, wherein the first data comprises patient data requested by a clinician.

15. The communicator of claim 12, wherein the first priority level is determined at least in part by a medical device.

16. The communicator of claim 12, wherein the communicator is configured to receive the criticality of the first data, where the criticality of the first data is determined by a medical device.

17. The communicator of claim 12, wherein the processor is further configured to establish a connection with the wireless network on an unscheduled event driven basis.

18. The communicator of claim 12, wherein the processor is further configured to select a second data transport mechanism among the plurality of disparate data transport mechanisms based at least in part on the first priority level.

19. The communicator of claim 12, wherein the communicator status comprises an infrastructural status of the communicator defining one or more data transport mechanisms available to it among the plurality of disparate data transport mechanisms.

20. The communicator of claim 12, wherein the processor is configured to receive second data to which a second priority level is assigned, wherein the second priority level is based at least in part on criticality of the second data and the communicator status, the processor further configured to execute program instructions for selecting a second data transport mechanism among the plurality of disparate data transport mechanisms based at least in part on the second priority level, and transmitting the second data via the wireless network using the second transport mechanism via the radio, wherein the second data transport mechanism is different than the first data transport mechanism.
