Venous Insufficiency Treatment Method

摘要

The method of treating varicose veins and other vascular diseases provides sclerosant fluid through a catheter into the body vessel to be treated. The catheter has a lumen and a plurality of sidewall exits. The sclerosant fluid is provided under sufficient pressure so that it comes out of each exit as a jet of fluid with sufficient velocity to impinge on the vessel wall substantially orthogonal to the wall and thus minimize dilution of the sclerosant fluid and optimize coverage. A movable sheath on the catheter permits selecting a portion of the exits to be uncovered and thus create an infusion zone for the jets of sclerosant fluid which approximately match a desired treatment zone.

1. A method of treating a vascular disease comprising:
inserting into a body vessel a catheter having a lumen, an end hole and a plurality of exits longitudinally disposed along the sidewall of the catheter, the end hole having a proximal opening and a distal opening; inserting through the catheter an occluding wire having an occluding element having a larger size than the size of the end hole so as to occlude the proximal opening of the end hole; and delivering a sclerosant fluid into the lumen under pressure such that the fluid flows through the exits and impinge on the wall of the body vessel without using an occlusion balloon and without using tumescent anesthesia.
