METHOD AND APPARATUS FOR MANIPULATING MOVEMENT OF A MICRO-CATHETER

摘要

A medical device and method for manipulating movement of a micro-catheter, the device comprising an elongated tubular member having at least one lumen therein, wherein the lumen is proximally coupled to a pressurized fluid control system configured to regulate fluid flow through the elongated tubular member. An aperture is disposed near a distal end of the elongated tubular member, the aperture being in fluid communication with the at least one lumen. In one aspect, the aperture is oriented at an angle which is non parallel to the longitudinal axis of the elongated tubular member. A nozzle is coupled to the aperture, wherein the nozzle is configured to regulate pressurized flow out of the catheter to manipulate movement of the distal end of the elongated tubular member.
