Abstract

Disclosed is a method and apparatus for configuring an external device so that may communicate with and an implantable medical device in accordance with a desired telemetry protocols. The external device utilizes a telemetry module can be loaded with a protocol driver necessary for communicating with the implantable medical device. Once the desired protocol driver has been installed in the telemetry module, the telemetry module enables communication with the implantable medical device.

Claims

1. A configurable telemetry unit for communicating with an implantable medical device, the telemetry unit comprising:

a host interface for receiving a protocol driver from a host device, the protocol driver configured to enable communication between the telemetry unit and the implantable medical device in accordance with a telemetry protocol recognized by the implantable medical device;

a memory;

a platform software stored in the memory, the platform software configured to install the protocol driver;

an antenna for transferring signals to and from the implantable medical device via telemetry; and

a protocol driver interface for receiving a signal from the protocol driver, generating a transmit signal having parameters specified by the protocol driver, and providing the transmit signal to the antenna.

2. The system of claim 1, wherein the host interface is configured for wireless reception of the protocol driver.

3. The system of claim 1, wherein the platform software is configured to verify the protocol driver is correctly installed.

4. The system of claim 1, wherein the host interface is configured to receive power and data over a single cable.

5. A method of communicating between a host device and an implanted device, comprising:

(a) loading a protocol driver on a host device;

(b) installing the protocol driver in an external telemetry unit;

(c) communicating a message from the host device to the implanted device through the external telemetry unit; and

(d) receiving a response from the implanted device that is communicated to the host device through the external telemetry unit.

6. The telemetry unit of claim 5, wherein the loading the protocol driver in (a) comprises:

(i) inserting a flash memory card into the host device, wherein the flash memory card contains the protocol driver.

7. The method of claim 5, wherein installing the protocol driver in (b) comprises:

(i) determining whether the protocol driver is already installed in the external telemetry unit;

(ii) if the protocol driver is not installed, providing the protocol driver to the external telemetry unit from the host device; and

(iii) using a platform software stored in the external telemetry unit to install the protocol driver in the external telemetry unit.

8. The method of claim 5, further comprising:

(e) determining if the protocol driver is loaded on the external telemetry unit; and

(f) loading the protocol driver on the external telemetry unit.

9. The method of claim 8, wherein the loading in (I) comprises:

(i) sending data over a wireless network from the host device to the external telemetry unit.

10. A method of communicating between a host device and an implanted device, comprising:

(a) receiving a message, from the host device, for the implanted device, in an external telemetry device, the message including a request to use a first protocol driver;

(b) determining whether the first protocol driver is installed in the external telemetry device for communicating with the implanted device;

(c) if the first protocol driver is not installed, automatically installing the first protocol driver; and

(d) communicating the message to the implanted device.

11. The method of claim 10, wherein the step of installing the first protocol driver in (c) comprises:

(i) obtaining the first protocol driver;

(ii) installing the first protocol driver; and

(iii) verifying that the first protocol driver is correctly installed.

12. The method of claim 11, wherein the step of obtaining in (i) comprises:

(1) receiving the first protocol driver from a host device.

13. The method of claim 12, wherein the step of obtaining in (i) further comprises:

(2) requesting the host device provide the first protocol driver.

14. The method of claim 11, wherein the step of installing the correct driver in (c) further comprises:

(iv) saving the first protocol driver into memory on the external telemetry device.

15. The method of claim 10, wherein the step of determining in (b) comprises:

(i) comparing the identification number of the first protocol referenced in the message with the identification number of the second protocol driver, the second protocol driver being installed;

(ii) if the identification of the second protocol driver does not match the identification number of the first protocol driver, providing an indication to the host device; and

(iii) uninstalling the second protocol driver.
