Wiping mechanism for a Y-connector

1. A robotic catheter system, the system comprising:

a first drive mechanism configured to interact with an elongated medical device to cause the elongated medical device to move along its longitudinal axis;

a wiper assembly having a first wiping surface moving toward and away from the longitudinal axis;

a controller providing a signal to a motor to move the first wiping surface toward the longitudinal axis when the elongated medical device is being withdrawn from a patient; and

a Y-connector and a hemostasis valve, the wiping surface being positioned intermediate the Y-connector and hemostasis valve and the first drive mechanism;

wherein the first wiping surface contacts a surface of the elongated medical device to remove fluid from the elongated medical device;

wherein the first wiping surface is on an exterior of a roller wheel that rotates about an axis that is perpendicular to the longitudinal axis of the elongated medical device.

2. The robotic catheter system of claim 1 , wherein the first wiping surface is an absorbent material.

3. The robotic catheter system of claim 1 , wherein the controller automatically provides a signal to a motor to move the first wiping surface away from the elongated medical device when the drive mechanism is driving the elongated medical device into a patient.

4. The robotic catheter system of claim 1 , further including a cleaner depositing fluid on to the elongated medical device as the medical device is being withdrawn from the patient.

5. The robotic catheter system of claim 1 , wherein the elongated medical device is a flexible guide wire.

6. The robotic catheter system of claim 1 , wherein the wheel is driven by a motor when the elongated medical device is being withdrawn from the patient.

7. A robotic catheter system, the system comprising:

a first drive mechanism configured to interact with an elongated medical device to cause the elongated medical device to move along its longitudinal axis;

a wiper assembly having a first wiping surface moving toward and away from the longitudinal axis;

a controller providing a signal to a motor to move the first wiping surface toward the longitudinal axis when the elongated medical device is being withdrawn from a patient; and

a cleaner depositing a fluid on to the elongated medical device as the medical device is being withdrawn from the patient;

wherein the first wiping surface contacts a surface of the elongated medical device to remove fluid from the elongated medical device;

wherein the fluid is deposited by a remote controlled dispenser and the rate of fluid flow is determined by the controller and a function of one or more of a user input, speed in which the elongated medical device is being withdrawn.

8. A robotic catheter system, the system comprising:

a first drive mechanism configured to interact with an elongated medical device to cause the elongated medical device to move along its longitudinal axis;
