Abstract

A technique allows for an electrical connection between a thermal abrasion heating catheter and the energy delivery console that utilizes serial communication. Accordingly, the serial communication allows data such as measured temperature, start/stop status, intended treatment area, device identification, device calibration parameters and/or use history to be conveyed along the same wires that deliver power to a heating element. For example, data can be conveyed along a two wire connection and provided at a frequency that is filtered out so that it is not delivered to a heating feature. In this example, one wire provides power to the heating element, one wire provided communication from the energy delivery console, and a third wire provides a common ground which the heating catheter uses to communicate with the energy delivery console.

Claims (24)

1. A method comprising:

receiving, by a catheter plug-in jack connection, a catheter cable assembly having a wire configuration that includes a power delivery wire, a communication wire, and a shared power delivery and communication ground wire;

sending, by an energy delivery console CPU disposed within an energy delivery console, signals to the catheter plug-in jack connection through a filter to filter out electromagnetic interference from the signals; and

filtering, by a shared power delivery and communication legitimizer (SPDCL) in electrical communication with the energy delivery console CPU and the catheter plug-in jack connection, communication signals sent over the shared power delivery and communication ground wire to the catheter plug-in jack connection.

2. The method of claim 1 , wherein the catheter cable assembly is shielded.

3. The method of claim 1 , wherein the filter is an EMI filter.

4. The method of claim 1 , wherein the SPDCL further includes a low pass filter.

5. The method of claim 4 , wherein the SPDCL further includes a Schmitt buffer.

6. The method of claim 1 , wherein the SPDCL further includes a Schmitt buffer.

7. The method of claim 1 , wherein the SPDCL further includes a discriminator.

8. The method of claim 4 , wherein the SPDCL further includes a discriminator.

9. The method of claim 5 , wherein the SPDCL further includes a discriminator.

10. The method of claim 1 , further comprising:

sending, by the energy delivery console CPU, signals to the catheter plug-in jack connection through a voltage switch.

11. The method of claim 1 , further comprising:

sending, by the energy delivery console CPU, signals to the catheter plug-in jack connection through a power driver.

12. The method of claim 10 , further comprising:

Sending, by the energy delivery console CPU, signals to the catheter plug-in jack connection through a power driver.

13. The method of claim 1 , further comprising:

sending, by the energy delivery console CPU, signals to the catheter plug-in jack connection through an over current and short protection circuit.

14. The method of claim 10 , further comprising:

sending, by the energy delivery console CPU, signals to the catheter plug-in jack connection through an over current and short protection circuit.

15. The method of claim 11 , further comprising:

sending, by the energy delivery console CPU, signals to the catheter plug-in jack connection through an over current and short protection circuit.
