Abstract

The present invention describes a method of treating restless leg syndrome by eliminating venous reflux in an underlying vein. The malfunctioning vein can be removed or ablated by inserting a catheter into the vein that transmits sufficient energy to coagulate or ablate the lining of the vein causing it to permanently close, eliminating the source of venous reflux and the symptom of restless leg syndrome.

Claims (11)

1. A method for treatment of restless leg syndrome in a patient with reflux in a leg vein, the method comprising the following steps:

A. Performing an exam of veins contributing to vascular insufficiency and reflux;

B. Obtaining percutaneous access of the vessel being treated using a Seldinger or equivalent technique;

C. Advancing a catheter with catheter tip through an introducer sheath until it is approximately 1-2 cm below the saphenofemoral junction (SFJ) or the saphenopopliteal junction (SPJ) or at the appropriate distance based on the junction or vein being treated;

D. Confirming position of the catheter tip such as with ultrasound, aiming beam visualization, or equivalent;

E. Draining blood from the vein using elevation, suction, compression, vein spasm, or other technique;

F. Injecting local anesthesia around the vein being treated; and

G. Initiating treatment with a device which emits a diode laser or other laser source, electrical current, radiofrequency waves, microwaves, ultrasound or other source of electromagnetic energy which penetrates into regions of tissue.

2. The method of claim 1 further comprising the step of increasing wattage of energy delivered to tissue as desired.

3. The method of claim 1 further comprising the step of determining endpoint of treatment by observing indications of adequate tissue response, such as slowing or stopping of forward movement of flow, thickening of the vein wall, contracting of the vein, and decreasing size of the lumen of the vein.

4. The method of claim 1 further comprising the step of determining successful treatment by observing, such as with ultrasound, following treatment, any one of the group consisting of vein appearing more dense and thickened (more echogenic), vein less compressible with pressure from the ultrasound probe, vein lumen is noticeably smaller in size, and vein does not demonstrate spontaneous flow.
