An apparatus that includes two syringes, or a“double barrel syringe,”includes one syringe that injects or infuses while the other syringe aspirates. The double barrel syringe is a hand-held, hand-operated device with which injection and aspiration may be effected by a single action. The double barrel syringe may include a handle with two member. A first member includes one arm that pivotally couples to a plunger of a first syringe and another arm that pivotally couples to a barrel of a second syringe. A second member of the handle includes one arm that pivotally couples to a barrel of the first syringe and another arm that pivotally couples to a plunger of the second syringe. Methods for injecting or infusing simultaneously with aspirating are also disclosed.
