An apparatus that includes two syringes, or a “double barrel syringe,” includes one syringe that injects or infuses while the other syringe aspirates. In the double barrel syringe, injection and aspiration may be effected by a single action. The double barrel syringe may include a handle with two members. A first member of such a handle 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.
