Venous disease treatment

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.

What is claimed is: 
     
         1 . A system comprising:
 a heating catheter including a heating element;   an energy delivery console;   a serial communication cable connecting the heating catheter to the energy delivery console including:
 a power delivery wire; 
 a communication wire; 
 a shared ground wire providing a return path for the power delivery wire and the communication wire to the energy delivery console.
