Abstract

Systems, apparatus, methods and computer-readable storage media facilitating telemetry overuse reduction in a medical device, such as an implantable medical device (“IMD”) are provided. In one embodiment, an IMD includes a housing configured to be implanted at least partially within a patient, a memory and circuitry within the housing and a processor that executes executable components stored in the memory. The executable components include: a communication component configured to establish a telemetry connection with an external device to communicate data associated with sensed physiological data or therapy; and an authorization component configured to determine whether the external device is authorized to communicate with the IMD, wherein the communication component is further configured to disable the telemetry connection with the external device and prevent additional communication with the external device for a defined period of time based on a determination that the external device fails to be authorized to communicate with the IMD.

First claim

What is claimed is:

1. A medical device comprising:
a housing;
a memory, within the housing, that stores executable components; and
circuitry, within the housing, and configured to at least one of obtain sensed physiological data associated with the patient or deliver a therapy to the patient;
a processor, within the housing, that executes the executable components stored in the memory, wherein the executable components comprise:
a communication component configured to establish a wireless communication session with a second device to communicate data associated with at least one of the sensed physiological data or the therapy; and
an authorization component configured to determine whether the second device provided authorization for the wireless communication session with the medical device, wherein the communication component is further configured to disable the wireless communication session with the second device and prevent additional communication with at least the second device for a defined period of time based on a determination that the second device failed to provide authorization for the wireless communication session with the medical device.

2. The medical device of claim 1 , wherein the communication component is further configured to prevent the additional communication with other devices for the defined period of time based on the determination that the second device failed to provide authorization for the wireless communication session to communicate with the medical device.

3. The medical device of claim 1 , wherein the communication component is configured to establish the wireless communication session with the second device using a Bluetooth Low Energy communication protocol.

4. The medical device of claim 1 , wherein the authorization component is configured to determine whether the second device provided authorization for the wireless communication session with the medical device based on reception of valid authorization information from the second device.

5. The medical device of claim 1 , wherein the authorization component is configured to determine whether the second device provided authorization for the wireless communication session with the medical device based on reception of a defined packet from the second device within a defined window of time following reception of a request, from the second device, to establish the wireless communication session.

6. The medical device of claim 1 , wherein the authorization component is configured to determine whether the second device provided authorization for the wireless communication session with the medical device based on reception of a defined packet from the second device within a defined window of time following transmission of an acknowledgment message to the second device by the medical device, wherein the acknowledgment message indicates the medical device has received a request, from the second device, to establish the wireless communication session.

7. The medical device of claim 1 , wherein the authorization component is further configured to associate the second device with a storage cell of the memory that characterizes the second device as unauthorized to communicate with the medical device based on the determination that the second device failed to provide authorization for the wireless communication with the medical device, and wherein the communication component is configured to reject future requests, received from the second device, to pair with the medical device, based on association of the second device with the storage cell.

8. The medical device of claim 1 , further comprising:
a regulation component configured to determine, based on the determination that the second device failed to provide authorization for the wireless communication with the medical device, a number of previous failed attempts to authorize the second device in association with establishing one or more previous wireless communications sessions with the medical device, and
wherein the communication component is further configured to disable the wireless communication session with the second device and prevent the additional communication with the second device for the defined period of time based on the determination that the second device failed to provide authorization for the wireless communication session with the medical device and a determination that the number of previous failed attempts exceeds a threshold amount.

9. The medical device of claim 8 , wherein based on the determination that the second device failed to provide authorization for the wireless communication session with the medical device and the determination that the number of previous failed attempts exceeds the threshold amount, the regulation component is further configured to determine an amount of wireless communication conducted by the medical device over a defined period of time, and
wherein the communication component is further configured to disable the connection with the second device and enable additional communication with the second device and other devices based on a determination that the amount of communication fails to exceed the threshold amount.

10. The medical device of claim 8 , wherein based on the determination that the second device failed to provide authorization for the wireless communication session with the medical device and the determination that the number of previous failed attempts exceeds the threshold amount, the regulation component is further configured to determine an amount of communication conducted by the medical device over another defined period of time, and
wherein the communication component is further configured to disable the wireless communication session with the second device and prevent additional communication with the second device and other devices based on a determination that the amount of wireless communication exceeds the threshold amount.

11. The medical device of claim 1 , further comprising:
a regulation component configured to determine, based on the determination that the second device failed to provide authorization for the wireless communication session with the medical device, a number of requests received by the medical device from one or more unauthorized devices over another defined period of time, and
wherein the communication component is further configured to disable the wireless communication session with the second device and prevent the additional communication with the second device and other devices for the defined period of time based on the determination that the second device failed to provide authorization for the wireless communication session with the second device and a determination that the number of requests received by the medical device from the one or more unauthorized devices exceeds a threshold amount.

12. The medical device of claim 11 , wherein the communication component is configured to prevent the additional communication with the second device and the other devices by deactivating a transceiver of the medical device for the defined period of time.

13. The medical device of claim 1 , further comprising:
a regulation component configured to determine, based on the determination that the second device failed to provide authorization for the wireless communication session with the medical device, an amount of communication conducted by the medical device over another defined period of time, and
wherein the communication component is further configured to disable the connection with the second device and prevent the additional communication with the second device and other devices for the defined period of time based on the dete
