This invention is a hemostasis cannula comprising a housing (10) having a passage (11) therethrough sized to receive a catheter and a valve body (1') mounted in the passage. The valve body (1') includes an opening (3') therethrough which forms a seal around a catheter enclosed within the cannula. When the catheter is removed, the valve body (1') closes thus blocking airflow into the patient's blood vessel, and also blocking blood flow out of the patient's blood vessel.
