ABSTRACT:
A slit valve medical catheter includes a flexible tube the distal end of which is closed. A length of resilient tubing is mounted coaxially to the distal end segment of the tube so that the tubing extends along the inside or outside surface of the tube. The tubing is slitted lengthwise and an aperture is formed in the tube wall directly opposite each slit with the aperture being wider than the slit so that portions of the tubing wall on opposite sides of each slit overhang the sides of the corresponding aperture.
