ABSTRACT:
A catheter defines a flexible, tubular body in which the tubular body carries a tubular reinforcing sleeve made of strands. By this invention the catheter defines at least one side hole which communicates through the tubular body and tubular reinforcing sleeve. Greater resistance against collapse is thus provided to the section of the catheter which defines the side hole or preferably side holes.
