  • Hemostasis mechanism and method
    Patent number: 9675792
    Abstract: A hemostasis mechanism includes a housing having a valve body, a connector coupled to a distal end of the valve body, and a cap coupled to a proximal end of the valve body. A first valve is within the housing and has a fixed state of axial compression between the valve body and the cap. A second valve is within the housing and has a range of states of axial compression between the valve body and the connector. The first valve has a self-closing bias and forms a lower pressure seal about a medical device pushed therethrough. The second valve has a self-opening bias and forms a higher pressure seal about the medical device via adjustment of its state of axial compression.
