A hemostasis valve apparatus includes (i) a valve body having a lumen therethrough; (ii) a first resiliently deformable seal disposed within the valve body; and (iii) a plunger having a lumen extending therethrough. A passageway extends through the lumens of the plunger and valve body. A cap movably coupled to the valve body selectively moves the plunger along the valve body, thereby selectively compressing the seal. A connector coupled to the plunger is configured to couple the plunger in fluid communication with a fluid delivery means for delivering fluid to the valve. The valve has a substantially linear configuration for convenient storage and use. The valve also features a second seal for sealing the passageway extending through the lumens.
