Abstract

Claims (24)

1. A vein ablation system, comprising:

a catheter having an elongated body;

an ablation device at a distal portion of the elongated body;

a control device at a proximal portion of the elongated body, the control device comprising a single actuator configured to simultaneously control an injection of a chemical agent into a target vessel and a defined movement of the ablation device, wherein a rate of the injection of the chemical agent into the target vessel and a rate of the defined movement of the ablation device is customizable relative to one another; and

a rate input configured to control the rate of the injection of the chemical agent into the target vessel and the rate of the defined movement of the ablation device.

2. The vein ablation system of claim 1 , wherein the defined movement is a longitudinal translation of the ablation device through the target vessel.

3. The vein ablation system of claim 2 , wherein the rate input is configured to control the rate of the injection of the chemical agent relative to a distance of the longitudinal translation of the ablation device.

4. The vein ablation system of claim 1 , wherein the defined movement is a rotation of the ablation device about a central longitudinal axis.

5. The vein ablation system of claim 4 , wherein the rate input is configured to control the rate of the injection relative to a number of rotations of the ablation device.

6. The vein ablation system of claim 1 , wherein the defined movement is a vibration of the ablation device about a central longitudinal axis.

7. The vein ablation system of claim 1 , wherein the defined movement is an agitation of the ablation device about a central longitudinal axis.

8. The vein ablation system of claim 1 , wherein the ablation device defines a sinusoidal shape, and wherein the ablation device is configured to ablate the target vessel via the defined movement.

9. The vein ablation system of claim 8 , wherein a distal portion of the ablation device comprises a spherical tip.

10. The vein ablation system of claim 1 , further comprising a motor operatively coupled to the ablation device and configured to cause the ablation device to perform the defined movement when power is supplied to the motor.

11. The vein ablation system of claim 10 , wherein the motor is configured to cause the injection of the chemical agent into the target vessel when power is supplied to the motor.

12. The vein ablation system of claim 1 , wherein the chemical agent comprises a sclerosant.

13. The vein ablation system of claim 1 , wherein the chemical agent is configured to be injected through the elongated body about the ablation device.

14. The vein ablation system of claim 1 , wherein the control device further comprises a distance display configured to indicate a distance between the control device and the ablation device.

15. The vein ablation system of claim 14 , wherein the distance display comprises a plurality of demarcations configured to indicate a distance between the control device and the ablation device.

16. The vein ablation system of claim 15 , wherein the distance display is configured to indicate the rate of the injection of the chemical agent into the target vessel.

17. The vein ablation system of claim 1 , wherein the control device further comprises a sliding mechanism configured to longitudinally translate the ablation device.

18. The vein ablation system of claim 1 , wherein the chemical agent is configured to be injected through the ablation device.

19. The vein ablation system of claim 1 , wherein the ablation device comprises a microtube, and wherein the ablation device is configured to ablate the target vessel via the defined movement.

20. The vein ablation system of claim 19 , wherein the microtube defines a fluid aperture, and wherein the chemical agent is configured to be injected through the microtube.
