Vascular treatment devices and methods
View Patent ↗An apparatus for performing a vascular treatment includes an intraluminal member that is controllingly moved during the vascular treatment. The intraluminal member of the vascular treatment device can be connected to a motor. The intraluminal member may be configured to retain endothelium during the vascular treatment procedure.
1. A vascular treatment method comprising the following steps:
advancing an elongated intraluminal member from an access site and into a vein having an inner vessel wall comprising endothelium tissue, wherein the intraluminal member comprises a single wire having a distal portion configured to produce damage to the inner vessel wall and retain endothelium tissue within cavities disposed on the distal portion of the wire;
damaging the inner vessel wall by performing a defined movement of the portion of the intraluminal member against the endothelium tissue, wherein the damaging comprises removing endothelium tissue from the inner vessel wall and retaining the endothelium tissue within the cavities on the distal portion of the wire while performing the defined movement.
2. The method of claim 1 , further comprising injecting sclerosant into the vein and onto the damaged inner vessel wall.
3. The method of claim 1 , wherein the defined movement is rotation of the intraluminal member.
4. The method of claim 1 , wherein the distal portion of the wire further includes sharp edged protrusions.
5. The method of claim 1 , wherein the distal portion of the wire further includes a roughened surface.
6. The method of claim 1 , wherein the wire includes a roughened and hemispherical distal tip.
