MEDICAL INSTRUMENT VALVE Inventor: Richard A. Hillstead ABSTRACT OF THE DISCLOSURE A hemostasis valve is provided for catheters or the like, comprising an elastomeric partition valve secured in a housing. A linear slit extends through the partition valve between the major faces thereof. By this invention, the partition of the valve has at least one concave face through which the slit extends. Such a partition valve provides further improved sealing characteristics over a wide range of diameters of catheters, leads, or the like penetrating the partition valve, particularly reducing frictional resistance to catheter advancement and rotation through the valve and also reducing catheter collapse in the valve.
