Abstract
The leading end of a catheter tube is directionally controlled by reactive forces imparted to the tube by pressurized control fluid issued from selected control ports defined through the tube proximate its forward end. The reactive forces can be used to bend, turn, propel and otherwise maneuver the advancing catheter. A circumferentially pleated section of the tube may be provided to facilitate bending. A flexible and annular flow baffle may be disposed in the control port outflow path to minimize control flow impact on the vessel wall and/or to affect thrust direction.
