ABSTRACT:
A syringe array (10) for holding a plurality of syringes (12), each syringe having a barrel (14), a plunger (18) and a needle (16), the syringe array (10) including a distal assembly (50) which holds the plungers (18) of the plurality of syringes (12) and by which all of the plurality of plungers (18) are urged to move in unison, a pivot assembly (52) wherein a portion of each the barrels (14) of the plurality of syringes (12) is pivotally attached to a pivot (92, 94) and a proximal assembly (48) wherein each needle (16) of the plurality of syringes (12) is positioned with a controlled center-to-center spacing (100, 102) from each other. An adjusting portion (62, 64, 70) of the syringe array (10) is adjustable to controllably change the needle center-to-center spacing from a first spacing (100) to at least a second spacing (102) as the barrel portions (14) are allowed to rotate about the pivots (92, 94).
