Claim:
1. A hemostasis mechanism comprising: a housing having an outer surface, and an inner surface defining a through-bore having a longitudinal axis; a deformable seal extending circumferentially around the longitudinal axis and being positioned within the through-bore, and wherein a clearance extends between the deformable seal and the inner surface; a plunger guided for translation within the housing from a first position to a second position to displace a fluid to the clearance, such that a fluid pressure in the clearance is increased to deform the deformable seal into sealing contact with a medical device within the through-bore; an actuator for the plunger including a linkage having a first arm rotatable about a first axis relative the housing, and a second arm rotatable about a second axis relative the first arm and being coupled to the plunger, such that rotation of the first arm is converted via rotation of the second arm into translation of the plunger between the first and second positions; and wherein the linkage at the second axis is positioned within the housing, and trapped to move between contact with a first stop within the housing and contact with a second stop within the housing.
