Venous disease treatment
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.
1. An energy delivery console comprising:
a catheter plug-in jack connection configured to receive 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;
an energy delivery console CPU disposed within the energy delivery console, the energy delivery console CPU being configured to send signals to the catheter plug-in jack connection through a filter to filter out electromagnetic interference from the signals; and
a shared power delivery and communication legitimizer (SPDCL) in electrical communication with the energy delivery console CPU and the catheter plug-in jack connection, wherein the SPDCL is configured to filter communication signals sent over the shared power delivery and communication ground wire to the catheter plug-in jack connection.
2. The energy delivery console of claim 1 , wherein the catheter cable assembly is shielded.
3. The energy delivery console of claim 1 , wherein the filter is an EMI filter.
4. The energy delivery console of claim 1 , wherein the SPDCL further includes a low pass filter.
5. The energy delivery console of claim 4 , wherein the SPDCL further includes a Schmitt buffer.
6. The energy delivery console of claim 5 wherein the SPDCL further includes a discriminator.
7. The energy delivery console of claim 4 , wherein the SPDCL further includes a discriminator.
8. The energy delivery console of claim 1 wherein the SPDCL further includes a Schmitt buffer.
9. The energy delivery console of claim 1 wherein the SPDCL further includes a discriminator.
10. The energy delivery console of claim 1 , wherein the energy delivery console CPU is further configured to send signals to the catheter plug-in jack connection through a voltage switch.
11. The energy delivery console of claim 10 , wherein the energy delivery console CPU is further configured to send signals to the catheter plug-in jack connection through a power driver.
12. The energy delivery console of claim 10 , wherein the energy delivery console CPU is further configured to send signals to the catheter plug-in jack connection through an over current and short protection circuit.
13. The energy delivery console of claim 1 wherein the energy delivery console CPU is further configured to send signals to the catheter plug-in jack connection through a power driver.
14. The energy delivery console of claim 13 , wherein the energy delivery console CPU is further configured to send signals to the catheter plug-in jack connection through an over current and short protection circuit.
15. The energy delivery console of claim 1 , wherein the energy delivery console CPU is further configured to send signals to the catheter plug-in jack connection through an over current and short protection circuit.
