ABSTRACT:
An external surface of a catheter body includes a pressure responsive slit formed in an indentation wherein a wall thickness of the catheter body within the indentation is less than a wall thickness of a major portion of the catheter body. Material exits a lumen of the catheter body, via the pressure responsive slit, when a pressure inside the lumen exceeds an external pressure.
