  • Publication number: 20020062106
    Abstract: A medical closure device for providing a passage into or out of the body. A resilient member at least partially defines the passage, and a two-part body is disposed to permit relative rotation its parts about the passage axis. The first body portion compresses and supports the resilient member. Cam surfaces on the second body control a compression member which is disposed in a radially extending aperture of the first body portion and biased radially outwardly by the resilient member to maintain contact with the cam surface. Relative rotation of the body portions about the axis moves the cam surface relative to the compression member, causing radial displacement of the compression member from a first position (in which the passage is relatively uncompressed and open) to a second position (in which the passage is restricted).
