Restless leg syndrome treatment
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.
1. A method of treating restless leg syndrome, the method comprising the step of eliminating reflux from an underlying vein which does not exhibit other varicose vein symptoms by using an endovenous catheter and closing the underlying leg vein permanently with energy.
2. The method of claim 1 in which the energy is of the type selected from the group consisting of infrared, ultraviolet, visible, radio frequency, ultrasound and laser.
3. The method of claim 1 in which the step of eliminating reflux from an underlying vein comprises using foam sclerotherapy.
4. A method of treating restless leg syndrome comprising the step of using laser energy to eliminate reflux in a short segment of vein which does not exhibit other varicose vein symptoms around the symptomatic region by closing the segment of the vein permanently with an endovenous catheter.
5. A method of treating restless leg syndrome, the method comprising the step of using laser energy delivered via endovenous catheter for eliminating venous reflux in an underlying vein in the absence of vein varicosities, ulcers or other visible symptoms, by closing the vein permanently.
6. An endovenous method of treating restless leg syndrome comprising the step of using a laser having a wavelength between about 1.2 and about 2.7 um to permanently heat and shrink collagen in a vessel wall which does not exhibit other varicose vein symptoms and permanently close the vessel.
7. The method of claim 6 further comprising the step of delivering the laser energy with a fiber optic laser delivery device.
8. The method of claim 7 in which the fiber optic laser delivery device is retracted at a rate of between about 0.5 mm/sec and about 5.0 mm/sec.
9. The method of claim 7 in which the fiber optic laser delivery device is introduced to the vein through an introducer catheter.
10. The method of claim 6 further comprising the following steps:
Inserting a fiber optic laser delivery device into the vein;
Using a pullback device to retract the fiber optic laser delivery device through the vein at a rate of between about 0.1 mm/sec and about 10.0 mm/sec while simultaneously delivering laser energy therefrom.
11. The method of claim 10 in which the pullback device is left off initially to let heat build up at the start therefore enabling a better closure of the vessel.
12. The method of claim 6 in which blood is removed from the vein prior to treatment with laser energy.
13. The method of claim 6 in which a laser energy emitting tip is prevented from making vein wall contact through the use of a coating around the tip of the fiber that makes a mechanical space between the emitting tip of the fiber and the vein wall.
14. The method of claim 6 in which a pulsed laser is used, the pulse width between 1 and 5000 microseconds.
15. The method of claim 6 in which a pulsed laser is used, the pulse width between 20 and 500 microseconds.
