Abstract:
A self-occluding catheter comprising:a body portion having a proximal end, a distal end, at least one internal fluid conduit extending between said proximal end and said distal end and an internal transverse bore in fluid communication with said internal fluid conduit;a spool slidably supported within said internal transverse bore of said body portion, said spool slidable between an open and a closed position; anda biasing device adjacent said spool for resiliently urging said spool to said closed position wherein said spool substantially blocks said internal fluid conduit of said body thereby preventing fluid flow between said distal end and said proximal end of said body;wherein a positive or a negative fluid pressure applied at said proximal end of said body portion overcomes said resilient urging provided by said biasing device on said spool to move said spool to said open position thereby permitting fluid flow between said distal end and said proximal end of said body portion, termination of said fluid pressure allowing said biasing device to return said spool to said closed position.
