Abstract

One aspect of the present disclosure involves a method. The method includes retrieving, from a diagnostic medical device, identification information that identifies a feature of the diagnostic medical device. A proprietary signal is generated in response to the identification information. The proprietary signal is sent to a medical measurement system to facilitate an unlocking of one or more programs to be executed on the medical measurement system. Another aspect of the present disclosure involves a method. The method includes detecting, through an electronic interface device, a coupling of a remote diagnostic medical device. Thereafter, a proprietary signal is received from the electronic interface device. An identity feature of the remote diagnostic medical device is ascertained based on the proprietary signal. One or more programs are unlocked for execution if the identity feature of the remote diagnostic medical device matches a predetermined identity feature.

Claims

1. A method of authorizing a medical device for use, the method comprising:

retrieving, by an electronic interface device, identification information from a diagnostic medical device that identifies a feature of the diagnostic medical device, the diagnostic medical device being configured to obtain pressure data within a vessel of a patient;

generating, by the electronic interface device, a proprietary signal based on the identification information; and

sending, from the electronic interface device, the proprietary signal through a channel configured to receive pressure data to a medical measurement system to facilitate an unlocking of one or more programs to be executed on the medical measurement system.

2. The method of claim 1, wherein:

the diagnostic medical device includes a pressure guide wire; and

the medical measurement system includes a hemodynamic system.

3. The method of claim 1, wherein the feature includes manufacturing information of the diagnostic medical device.

4. The method of claim 3, wherein the manufacturing information includes a type of the diagnostic medical device, an identity of the manufacturer of the diagnostic medical device, a manufacture site of the diagnostic medical device, expiration data of the diagnostic medical device, and date of past use of the diagnostic medical device.

5. The method of claim 1, further comprising:

receiving pressure data from the diagnostic medical device; and

sending the pressure wave data through the channel to the medical measurement system to be analyzed by the one or more unlocked programs.

6. The method of claim 5, wherein the pressure data includes blood pressure data.

7. The method of claim 5, wherein the one or more unlocked programs include a fractional flow reserve (FFR) calculation or an instantaneous wave-free ratio (iFR) calculation based on the pressure data.

8. A system, comprising:

a diagnostic medical device configured to obtain pressure data within a vessel of a patient and containing identification information that identifies a feature of the diagnostic medical device; and

an electronic interface device configured to serve as an interface between the diagnostic medical device and a medical measurement system, and is further configured to;

receive the identification information from the diagnostic medical device,

generate a proprietary signal based on the identification information, and

send, through a channel configured to receive pressure wave data, the proprietary signal to the medical measurement system to facilitate unlocking of one or more executable programs on the medical measurement system based on the proprietary signal.

9. The system of claim 8, wherein the one or more programs is unlocked if the feature of the diagnostic medical device matches a predetermined feature.

10. The system of claim 8, wherein the feature includes manufacturing information of the diagnostic medical device.

11. The system of claim 10, wherein the manufacturing information includes a type of the diagnostic medical device or an identity of the manufacturer of the diagnostic medical device.

12. The system of claim 8, wherein:

the diagnostic medical device includes a pressure guide wire; and

the medical measurement system includes a hemodynamic system.

13. The system of claim 8, wherein:

the electronic interface device is configured to send pressure data to the medical measurement system to be analyzed by the one or more unlocked programs.

14. The system of claim 13, wherein the pressure data includes blood pressure data.

15. The system of claim 13, wherein the one or more programs include a fractional flow reserve (FFR) calculation or an instantaneous wave-free ratio (iFR) calculation based on the blood pressure data.

16. A method, comprising:

detecting an attempted execution of a program stored on a non-transitory, computer-readable storage medium and configured to be executed by a processor;

querying one of;

an electronic interface device or a diagnostic medical device regarding identification information of the diagnostic medical device, the diagnostic medical device being configured to obtain pressure data within a vessel of a patient;

receiving, through a channel configured to receive pressure data, a proprietary signal generated based on the identification information;

determining, based on the proprietary signal, that the diagnostic medical device is authorized; and

unlocking the program for execution in response to determining that the diagnostic medical device is authorized.

17. The method of claim 16, wherein the detecting, the querying, the determining, and the unlocking are performed at least in part by a medical measurement system coupled to the diagnostic medical device through the electronic interface device.

18. The method of claim 16, wherein the querying is performed using a wired connection.

19. The method of claim 16, wherein the querying is performed wirelessly.

20. The method of claim 19, wherein the diagnostic medical device contains a radio-frequency identification (RFID) chip, and wherein the querying is performed through the RFID chip.

21. The method of claim 16, wherein:

the diagnostic medical device includes a pressure guide wire; and

the medical measurement system includes a hemodynamic system.

22. The method of claim 16, wherein the identification information includes a type of the diagnostic medical device, an identity of the manufacturer of the diagnostic medical device, a manufacture site of the diagnostic medical device, expiration data of the diagnostic medical device, and date of past use of the diagnostic medical device.

23. The system of claim 16, wherein the program includes a fractional flow reserve (FFR) calculation or an instantaneous wave-free ratio (iFR) calculation.
