Abstract

A method of managing catheter data for a catheter-based imaging system includes coupling a catheter to a control module. The catheter includes a memory structure that includes catheter management data. The control module includes a processor. The catheter management data is accessed from the memory structure using the processor. Patient tissue is imaged using control module settings that are selected based, at least in part, on the accessed catheter management data. At least one image is displayed based, at least in part, on the imaged patient tissue.

Claims

1. A method of managing catheter data for a catheter-based imaging system, the method comprising:

coupling a catheter to a control module, the catheter comprising a memory structure that comprises catheter management data, the control module comprising a processor;

accessing the catheter management data from the memory structure using the processor;

imaging patient tissue using control module settings that are selected based, at least in part, on the accessed catheter management data; and

displaying at least one image based, at least in part, on the imaged patient tissue.

2. The method of claim 1, wherein the catheter-based imaging system is one of an intravascular ultrasound system or an intracardiac echocardiography system.

3. The method of claim 1, wherein the catheter management data further comprises at least one of catheter verification data, catheter identification data, catheter manufacturing history data, at least one operational attribute or parameter of the catheter, or data related to a suggested lifespan of the catheter.

4. The method of claim 1, further comprising updating a database of recognized and verifiable catheters, as well as operational attributes and parameters of those catheters, by accessing catheter management data of the coupled catheter when the coupled catheter is verifiable, but not recognized, by the processor.

5. The method of claim 1, further comprising writing data to the memory structure that is collected during the imaging of patient tissue.

6. The method of claim 5, wherein writing data to the memory structure that is collected during the imaging of patient tissue comprises recording start and end times of an imaging procedure.

7. The method of claim 5, wherein writing data to the memory structure that is collected during the imaging of patient tissue comprises recording at least one of date, imaging procedure time, catheter rotational motor torque, or imaging pullback status.

8. The method of claim 5, further comprising performing a root cause analysis when the catheter fails, the root cause analysis including at least one or more of logging an error code, accessing system conductions at failure, or accessing data written to the memory structure collected during the imaging of patient tissue.

9. The method of claim 1, wherein imaging patient tissue using control module settings that are selected based, at least in part, on the accessed catheter calibration data comprises adjusting one or more of transmit output power, pulse profile, or receive path gain sensitivity of the catheter-based imaging system.

10. The method of claim 1, wherein imaging patient tissue using control module settings that are selected based, at least in part, on the accessed catheter calibration data comprises recording echo pulse data to permit improvement of frequency dependent algorithms used in at least one of harmonic imaging, tissue characterization, or lumen detection applications.

11. The method of claim 1, further comprising determining catheter functions of the catheter that are available for use during the imaging of patient tissue.

12. The method of claim 1, wherein coupling a catheter to a control module comprises sensing whether the catheter is coupled to the control module using at least one of an optical sensor, magnetic sensor, capacitive sensor, resistive sensor, or a mechanical sensor.

13. A computer-readable medium having processor-executable instructions for reading data from a memory structure disposed on a catheter, the processor-executable instructions when installed onto a device enable the device to perform actions, comprising:

accessing catheter management data from the memory structure;

imaging patient tissue using control module settings that are selected based, at least in part, on the accessed catheter management data; and

displaying at least one image based, at least in part, on the imaged patient tissue.

14. The computer-readable medium of claim 13, wherein the catheter management data further comprises at least one of catheter verification data, catheter identification data, catheter manufacturing history data, at least one operational attribute or parameter of the catheter, or data related to a suggested lifespan of the catheter.

15. The computer-readable medium of claim 13, wherein the actions further comprise updating a database of recognized and verifiable catheters, as well as operational attributes and parameters of those catheters, by accessing catheter management data of the coupled catheter when the coupled catheter is verifiable, but not recognized, by the processor.

16. The computer-readable medium of claim 13, wherein the actions further comprise writing data to the memory structure that is collected during the imaging of patient tissue.

17. A catheter-based imager comprising:

at least one imager and a memory structure disposed in a catheter at least partially insertable into a patient, the at least one imager and the memory structure each coupled to a control module; and

a processor in communication with the control module, the processor for executing processor-readable instructions that enable actions, including;

accessing catheter management data from the memory structure;

imaging patient tissue using control module settings that are selected based, at least in part, on the accessed catheter management data; and

displaying at least one image based, at least in part, on the imaged patient tissue.

18. The computer-readable medium of claim 17, wherein the catheter management data further comprises at least one of catheter verification data, catheter identification data, catheter manufacturing history data, at least one operational attribute or parameter of the catheter, or data related to a suggested lifespan of the catheter.

19. The catheter-based imager of claim 18, wherein the actions further comprise updating a database of recognized and verifiable catheters, as well as operational attributes and parameters of those catheters, by accessing catheter management data of the coupled catheter when the coupled catheter is verifiable, but not recognized, by the processor.

20. The catheter-based imager of claim 17, wherein the actions further comprise writing data to the memory structure that is collected during the imaging of patient tissue.
