A hemostasis valve having an adjustable quick-release mechanism the hemostasis valve includes a tubular body having a lumen therethrough and a compression chamber formed in one end that communicates with the lumen. A resilient compressible seal having a longitudinal passageway aligned with the lumen is disposed within the compression chamber. The compressible seal includes a raised annular portion projecting into the passageway. The compressible seal is configured to selectively seal and unseal the lumen in response to a compressive force exerted on said compressible seal by a plunger. Changing the compressive force exerted by the plunger on the seal allows for selectively and progressively reducing the size of an opening provided by the raised annular portion in the passageway. A quick-release mechanism, comprising a quick-release lever and a quick release assembly, is movably attached to the tubular body and communicates with the plunger. The quick-release mechanism allows the compressible seal to selectively be in a compressible position or in a released position. A spring tends to urge the plunger and seal into a compressed position. However, a rotatable end cap is operably interconnected between the quick-release mechanism and the plunger for progressively adjusting the amount of compression force exerted by the plunger onto the seal in order to selectively compress or release the compressible seal.
