Claim Text:
1. A hemostasis valve, comprising: a) a longitudinal valve housing having a major longitudinal axis, the longitudinal valve housing defining a conduit and having a proximal end and a distal end; b) a gasket within the housing, the gasket defining an interior conduit and having, c) a grip assembly at the proximal end of the longitudinal valve housing and linked to the proximal end portion of the gasket, the grip assembly being rotatable relative to the longitudinal valve housing, and including, d) an interference element within the longitudinal valve housing, the interference element defining teeth that interfere with the teeth of the ratchet and against which the teeth of the ratchet are biased, whereby rotation of the grip portion relative to the longitudinal valve housing causes rotation of the proximal end portion of the gasket relative to the distal end portion of the gasket, thereby changing the internal diameter of the internal conduit, and whereby rotational and longitudinal movement of the grip assembly relative to the longitudinal valve housing causes the teeth of the ratchet to disengage and reengage the interference element with the ratchet, re-engagement of the ratchet with the interference element locking the diameter of the internal conduit of the gasket in place upon termination of rotation of the grip assembly relative to the longitudinal valve housing.
