Abstract
Self-venting balloon dilatation catheter having an elongate flexible tubular member having at least one lumen therein extending longitudinally thereof. A balloon is carried by the flexible tubular member and is in communication with the lumen. A fitting is carried by the tubular member for inflating the balloon with a balloon inflating medium. A plurality of small passages are formed which permit air to escape from the interior of the balloon but inhibit the passage of the balloon inflation medium from the balloon.
