Abstract
A combination valve and clamping device is provided in which a flexible elastic inner lining is secured in a tubular outer shell having a port for introducing a fluid therebetween. A source of pressure such as a hypodermic syringe is used to cause the inner elastic sleeve to collapse and deform internally upon itself to surround and form a seal about a catheter located therein, positioning it within the shell. Alternatively, if nothing is present in the shell, the sleeve is collapsed on itself to prevent leakage of a fluid through the valve mechanism.
