Claim Text:
1. A method of permanently occluding a vein through the combined spasm of the vein and injection of an adhesive, comprising the following steps: advancing an elongated intraluminal member from an access site and into the vein, wherein the intraluminal member comprises a perturbing portion configured to perturb an inner vessel wall of the vein under user control when performing a defined movement; perturbing the inner vessel wall by performing the defined movement of the perturbing portion of the intraluminal member, thereby inducing a region of the vein to spasm and reduce its diameter; generating backflow of blood in the vein by performing the defined movement, the defined movement includes rotating the perturbing portion of the intraluminal member; and injecting sufficient adhesive at the region of the vein having a reduced diameter due to the induced spasm to occlude the vein permanently.
