Abstract
A triple lumen stone balloon catheter (1) having a tapered distal end (9). A lumen (24) dedicated to transmitting contrast media is dimensioned and adapted to conform to the shape of a kidney in a main shaft of the catheter and conform to the shape of a crescent in a distal end of the catheter. The geometric shaping of the contrast media lumen (24) enables wall thickness to be maintained within acceptable ranges to sustain desirable mechanical characteristics while allowing for enhanced contrast media flow. A method for employing the balloon catheter (1) is also disclosed.
