Abstract
A two-chambered, sequentially injectable syringe is disclosed. The syringe has two concentric barrels, substantially cylindrical in shape. The outer barrel has an open end adapted for receiving an inner barrel/first piston. The inner barrel/first piston contains a flushing liquid. The syringe has a second piston slidably movable in the inner barrel and a latching mechanism that can alternate between a locked configuration and an unlocked configuration. In the locked configuration, the latching mechanism prevents the second piston from substantially all longitudinal movement relative to the inner barrel. In the unlocked configuration, the latching mechanism permits longitudinal motion of the second piston within the inner barrel.
