ABSTRACT:
A hemostasis valve in which the valve member is a tubular, resilient gasket which may be compressed with variable pressure to provide a variable pressure seal to an elongated member extending through the tubular bore of the gasket. The gasket bore also defines at least one resilient, annular rib whereby the elongated member passing through the tubular gasket bore may be subjected at all times to at least a relatively low pressure seal from the resilient, annular rib, irrespective of the pressure of the variable pressure seal. Additionally, the pressure on the gasket may be applied and released by means of a pressure member positioned against the gasket. Structure is provided permitting longitudinal motion, but preventing rotational motion, of the pressure member. A rotatable cap is provided, with facing, mating spiral track means carried on both the inner face of th rotatable cap and outer face of the pressure member, to cause pressurizing advancement of the pressure member against the tubular gasket by rotation of the cap in one direction, and release of such pressurizing advancement by rotation of the cap in the other direction.
