ABSTRACT:
A hemostasis valve system for controlling a flow of fluid includes a housing having a chamber therein, and a valve disposed in the chamber. The valve comprises a plurality of elastomeric valve members, each having opposing shaped first and second faces, a shaped inner edge portion, and a shaped outer edge portion. The valve members are collectively structured and arranged in the valve such that the shaped faces and the shaped inner edges are engaged in interlocking relationship. The valve members have sufficient elasticity to define a yieldable opening along the engaged inner edge portions upon passage therethrough of a medical interventional device.
