ABSTRACT:
A catheter has a radially expandable end region containing a plurality of fluid containing channels. A circular assembly containing a plurality of cylinders each containing a piston is arranged so that each piston is connected with one channel. A rotary mechanical assembly is connected so that movement of an arm extending from the rotary assembly causes actuation of one or more pistons to cause selected channels in the catheter to be pressurized, expanding the radial portion of the catheter adjacent the pressurized channels and enabling the catheter to be more easily guided in the desired direction through bodily passageways.
