Claim:
1. A medical valve assembly for use in inserting a medical device into a body vessel of a patient, comprising: a tube extending between a first tube end and a second tube end to define a passageway extending along a longitudinal axis between said ends; a plunger plate extending radially from said second tube end of said tube; a valve housing surrounding said tube about said second tube end and extending from a first valve housing end to a second valve housing end; said valve housing including a flange extending radially inwards from said second valve housing end and disposed in spaced relationship with said plunger plate to define a distance extending therebetween; an elastomeric seal compressed between said plunger plate and said flange and having an inner diameter for use in establishing a variable seal of the medical valve assembly; a compression member disposed within said valve housing and biased against said plunger plate for decreasing said inner diameter to establish a closed condition of the medical valve assembly; a manual actuator connected to said valve housing for allowing a user to overcome the bias of said compression member and effectuate axial movement of said valve housing relative to said tube to vary the distance between said plunger plate and said flange and adjust said inner diameter of said elastomeric seal for variably sealing the medical valve assembly to a variety of differently sized medical devices; wherein said valve housing is movable relative to said tube to increase the distance between said flange and said plunger plate to allow said tubular elastomeric seal to expand and increase said inner diameter for establishing an open condition of the medical valve assembly; a first pivot extending radially from said tube and a second pivot extending radially from said valve housing; said manual actuator including a pair of lever arms pivotably connected to said first pivot and a pair of lever linkages pivotably connected to said second pivot; and each of said lever linkages extending from said second pivot to engage one of said respective levers for allowing the user to radially compress said pair of lever arms with a force to effectuate the increase in the distance between said plunger plate and said flange.
