Methods and systems for venous disease treatment

A method of treating a perforator vein of a patient, comprising the steps of:

• accessing the perforator vein of the patient at an access location located at or above a fascia layer of the patient with a cannula assembly;
• introducing a flexible heating catheter through the cannula assembly into the perforator vein at the access location at or above the fascia layer;
• advancing the heating catheter within the perforator vein, past the fascia layer, to a first treatment location within the perforator vein and at or below the fascia layer;
• activating a heating element of the heating catheter to provide heat therapy at the first treatment location;
• withdrawing the heating catheter within the perforator vein to a second treatment location within the perforator vein;
• and
• activating the heating element of the heating catheter to provide heat therapy at the second treatment location.

A method of delivering a heat based treatment to a perforator vein of a patient, comprising:

• coupling a heating catheter having a single 5 mm long heating element formed from a resistive coil positioned at a distal most end of the catheter to an energy delivery console using a TRS connector associated with the heating catheter;
• preparing the energy delivery console for delivery of thermal energy using the heating catheter by automatically recognizing the catheter as one with a single 5 mm long resistive heating element;
• accessing the vasculature of the patient using a needle and cannula assembly;
• introducing the heating catheter into the vasculature of the patient to an initial treatment site;
• initiating a single heating segment thermal delivery profile in the energy delivery console by pressing a button on a handle or a footswitch of the catheter;
• providing heat therapy at the initial treatment site according to the single heating segment thermal delivery profile while the energy generator monitors an output of a thermocouple associated with the heating element to a 130 C setpoint.
