Abstract

An apparatus for performing a vascular treatment. In some embodiments, the apparatus comprises a vascular therapy device comprising a vascular treatment device and a feeder. The vascular treatment device can connect to a wire configured for use in vascular treatment. The vascular treatment device can rotate the wire. The feeder can be configured for controller the longitudinal translation of the wire. The feeder and the vascular treatment device can be independently or combinedly controlled.

Claims

1. An apparatus for permanently occluding a vein, comprising:

an elongated intraluminal member shaped and dimensioned for passage through blood vessels of a subject, the intraluminal member including a proximal end and a distal end, wherein the distal end comprises a vein wall disruptor;

a source of sclerosant; and

a fluid channel between the source of sclerosant and the distal end of the elongated intraluminal member;

a first motor coupled to the intraluminal member to move the intraluminal member;

a second motor coupled to the intraluminal member to withdraw the intraluminal member.

2. The apparatus of claim 1, wherein the second motor is configured to variably withdraw the intraluminal member.

3. The apparatus of claim 2, wherein the second motor is configured to increase the rate of withdrawal of the intraluminal member.

4. The apparatus of claim 2, wherein the second motor is configured to decrease the rate of withdrawal of the intraluminal member.

5. The apparatus of claim 2, wherein the second motor is configured to withdraw the intraluminal member at a rate of approximately 1-4 mm per second.

6. The apparatus of claim 1, wherein the first motor is coupled to a first housing, and wherein the second motor is coupled to a feeder.

7. The apparatus of claim 6, wherein the feeder comprises a track into which the first housing is placed.

8. The apparatus of claim 6, wherein the feeder comprises a second housing.

9. The apparatus of claim 8, wherein the second housing comprises rollers configured to feed the intraluminal member.

10. A method for permanently occluding a vein through the combined disruption of a vein vessel wall and application of a sclerosant, comprising the following steps:

advancing an elongated intraluminal member from an access site and into the vein, wherein the intraluminal member has a portion thereof configured to produce damage to the inner vessel wall of the vein under user control when performing a defined movement;

damaging the inner vessel wall by performing the defined movement of the portion of the intraluminal member against the vein'"'"'s endothelium while simultaneously withdrawing the intraluminal member in an automated manner;

injecting sclerosant into the vein and onto the damaged inner vessel wall.

11. The method of claim 10, comprising withdrawing the intraluminal member at a non-constant rate during the damaging.

12. The method of claim 11, comprising increasing the rate of withdrawal of the intraluminal member during the damaging.

13. The method of claim 11, comprising decreasing the rate of withdrawal of the intraluminal member during the damaging.

14. The method of claim 10, comprising withdrawing the intraluminal member at a rate of approximately 1-4 mm per second.

15. An apparatus for permanently occluding a vein, comprising:

an elongated intraluminal member shaped and dimensioned for passage through blood vessels of a subject, the intraluminal member including a proximal end and a distal end, wherein the distal end comprises a vein wall disruptor;

means for moving the distal end of the intraluminal member to damage a vain wall; and

,

means for withdrawing the intraluminal member in an automated manner.
