Segmental vascular ablation

1. A method, comprising:

inserting a catheter into a vascular system of a patient, the catheter comprising a sheath including a working lumen, the sheath including a first distance marking and a second distance marking, and a wire including a proximal wire end and a distal wire end opposite the proximal wire end, the wire extending through the working lumen;

moving the catheter to a first treatment segment;

actuating a motor and rotating at least a portion of the catheter in response to actuating the motor;

abrading the first treatment segment for a predetermined amount of time in response to rotating at least the portion of the catheter;

moving the catheter out of the patient a distance approximately equal to a length from the first distance marking to the second distance marking to a second treatment segment, wherein the length is approximately equal to a treatment length of the distal wire end; and

abrading the second treatment segment for the predetermined amount of time in response to rotating at least the portion of the catheter.

2. The method of claim 1 , further comprising indicating, via a component selected from the group consisting of a light emitting diode (LED), a speaker, a display, and combinations thereof, that the predetermined amount of time has elapsed, wherein the component is electrically coupled to a power supply that provides electricity to the motor.

3. The method of claim 1 , further comprising:

retracting at least a portion of the sheath from the wire; and

exposing the distal wire end in response to retracting the portion of the sheath from the wire.

4. The method of claim 3 , wherein the wire is operatively coupled to a motor, and a limit switch is electronically coupled to the motor, the method further comprising:

allowing electricity to flow from a power supply to the motor, via the limit switch, in response to the sheath being in a fully retracted state; and

rotating the wire in response to allowing electricity to flow from the power supply to the motor.

5. The method of claim 4 , further comprising maintaining a longitudinal position of the catheter with respect to the first treatment segment, wherein the longitudinal position is defined by a distal end of the catheter with respect to the first treatment segment.

6. The method of claim 1 , wherein the catheter includes a warning track, the method further comprising indicating, via the warning track, that an end of a workable treatment length of the catheter has been reached.

7. The method of claim 1 , wherein a syringe is fluidly coupled to the catheter, the method further comprising:

injecting a fluid, via the syringe, at the first treatment segment; and

terminating an injection of the fluid prior to moving the catheter to the second treatment segment.

8. The method of claim 7 , wherein the wire is operatively coupled to a motor, and a limit switch is electronically coupled to the motor, the method further comprising:

maintaining a longitudinal position of the catheter with respect to the first treatment segment, wherein the longitudinal position is defined by a distal end of the catheter with respect to the first treatment segment;

retracting at least a portion of the sheath from the wire; and

exposing the distal wire end in response to retracting the portion of the sheath from the wire.

9. The method of claim 3 , further comprising:

extending the sheath about the wire; and

at least partially enclosing the distal wire end in response to extending the sheath about the wire.

10. The method of claim 9 , further comprising:

preventing electricity to flow from a power supply to the motor, via a limit switch, in response to the sheath being in a non-fully retracted state; and

terminating a rotation of the wire in response to preventing electricity to flow from the power supply to the motor.

11. The method of claim 5 , wherein the catheter includes a warning track, the method further comprising indicating, via the warning track, that an end of a workable treatment length of the catheter has been reached.

12. The method of claim 7 , further comprising:

injecting the fluid, via the syringe, at the second treatment segment; and

removing the catheter from the vascular system of the patient.

13. The method of claim 8 , further comprising:

allowing electricity to flow from a power supply to the motor, via the limit switch, in response to the sheath being in a fully retracted state;

actuating a motor and rotating at least a portion of the catheter in response to actuating the motor; and

rotating the wire in response to allowing electricity to flow from the power supply to the motor.

14. The method of claim 13 , wherein the catheter includes a warning track, the method further comprising indicating, via the warning track, that an end of a workable treatment length of the catheter has been reached.

15. The method of claim 13 , further comprising:

extending the sheath about the wire;

at least partially enclosing the distal wire end in response to extending the sheath about the wire; and

preventing electricity to flow from the power supply to the motor, via the limit switch, in response to the sheath being in a non-fully retracted state.

16. The method of claim 1 , further comprising detachably coupling the catheter to a controller.

17. The method of claim 16 , further comprising:

expanding an expandable foot of the controller; and

stabilizing the controller in response to expanding the expandable foot.

18. The method of claim 1 , further comprising changing a ratio of rotation between the catheter and the motor.

19. The method of claim 12 , further comprising terminating the injection of the fluid prior to removing the catheter from the vascular system of the patient.

20. The method of claim 15 , further comprising terminating a rotation of the wire in response to preventing electricity to flow from the power supply to the motor.
