    Patent number: 5843046
    Abstract: A catheter apparatus having a housing with a throughbore. A seal is mounted within the throughbore. The seal has a peripheral sealing surface that contacts an external surface of a sleeve when the sleeve is mounted within the throughbore. A one-way valve or check valve is mounted within the throughbore, preferably between the peripheral sealing surface and the sleeve. When the sleeve is withdrawn from the throughbore, the one-way valve prevents fluid, such as a blood sample, from flowing outside of the housing.
