ABSTRACT:
An improved catheter comprising a tubular body of flexible material designed for medical use and insertion into a body cavity. The catheter includes at least one opening towards the distal end for the drainage of fluids or their introduction or for monitoring pressures from the body cavity and at least one integral, flexible wing member attached to the outer wall of the catheter and flexible to extend outward and bear against the inner wall of the body cavity to be served by the catheter. In the preferred embodiment, two oppositely located wings are formed integrally into the catheter. An insertion and withdrawal tube is dimensioned to slide over the catheter and hold the wings close against the outer wall of the catheter to facilitate introduction and removal from a body cavity. The distal end of the tube is tapered to aid in deforming the wings into the catheter aligned retracted position.
