A hemostasis valve comprising: (a) a body having a central passage therein; (b) a seal having a central aperture therein, said seal being mounted in said central passage; and (c) a resilient, dome shaped diaphragm having a wall member with a single, linear slit therein, said diaphragm being mounted in said central passage, said diaphragm wall member having an inner bottom diaphragm surface, and an outer bottom diaphragm surface, said slit extending through said wall member from said inner bottom diaphragm surface to said outer bottom diaphragm surface, said wall member defining with said seal a diaphragm chamber within the space between said inner bottom diaphragm surface and said seal, whereby the side walls of said dome shaped diaphragm will act in cooperation with the walls of said central passage to resiliently urge said slit closed when no catheter is present therethrough.
