Abstract: A hemostasis cannula includes a housing having a passage therethrough sized to receive a catheter and a valve body mounted in the passage. The valve body includes an opening therethrough which forms a seal around a catheter enclosed within the cannula. In one embodiment, a ring of raised material surrounds the opening. In another embodiment, a ring of raised material surrounds the hole, and an internal ring of material lines at least a portion of the interior of the opening. The valve body is compressed within the cannula housing. When the catheter is removed, the valve body closes thus blocking air flow into the patient's blood vessel and also blocking blood flow out of the patient's blood vessel. The cannula housing also includes a side port for introducing fluids into the patient's blood vessel.
