Abstract
A hemostasis valve is disclosed herein. The hemostasis valve may include an inner bushing, a rotation sleeve, an elastomeric sleeve, and a biasing element. The rotation sleeve may extend about the inner bushing and be rotationally displaceable relative to the inner bushing. The elastomeric sleeve may include a first end operably coupled to the inner bushing, a second end operably coupled to the rotation sleeve, and an iris valve portion. Rotation of the rotation sleeve relative to the inner bushing may cause the iris valve to transition from an open state to a closed state. The biasing element may act between the rotation sleeve and inner bushing to bias the iris valve towards at least one of a closed state or an open state.
