EMBOLIC PARTICLE MIXING SYRINGE
First Claim
1. A syringe device for agitating and delivering a liquid medication to a patient comprising:
- an injecting member;
a first syringe configured to provide the liquid medication;
a second syringe in selective fluid communication with the injecting member and the first syringe, the second syringe being configured to receive the liquid medication from the first syringe and move the liquid medication to the injecting member for patient delivery; and
an accumulator in selective fluid communication with the second syringe, the accumulator being biased to an empty position, wherein the biased accumulator cooperates with the second syringe to agitate the liquid medication between the second syringe and the accumulator prior to patient delivery.

Abstract
A syringe device for agitating and delivering a liquid medication to a patient is provided. The device includes an injecting member, a first syringe, a second syringe and an accumulator. The first syringe is configured to provide the liquid medication to the device. The second syringe is configured to receive the liquid medication from the first syringe. The accumulator is biased to an empty position and cooperates with the second syringe to agitate the liquid medication back and forth between the second syringe and the accumulator. The second syringe is configured to move the liquid medication to the injecting member for patient delivery.

17. A syringe device for agitating and delivering a liquid medication to a patient comprising:
-
an injecting member; a first syringe configured to provide the liquid medication, the first syringe having a first barrel including a first plunger longitudinally slidable within the first barrel; a second syringe configured to fluidly communicate with the injecting member and the first syringe, the second syringe being configured to receive the liquid medication from the first syringe and move the liquid medication to the injecting member for patient delivery, the second syringe having a second barrel including a second plunger longitudinally slidable within the second barrel; an accumulator configured to fluidly communicate with the second syringe, the accumulator including a third barrel having a third plunger longitudinally slidable within the third barrel, the third plunger being biased to an empty position, wherein the first plunger of the first syringe forms the third barrel of the accumulator such that the accumulator is longitudinally slidable within the first syringe; a locking element configured to prevent the accumulator from longitudinally sliding within the first syringe when in a locked position; and a valve coupling the first syringe to the second syringe, the valve being selectively adjustable between a first position in which the first syringe and the accumulator are in fluid communication with the second syringe and in which the first syringe, the accumulator, and the second syringe are not in fluid communication with the injecting member, and a second position in which the first syringe and the accumulator are not in fluid communication with the second syringe or the injecting member and in which the second syringe is in fluid communication with the injecting member.

18. A method of agitating and delivering a liquid medication to a patient comprising the steps of:
-
providing a syringe device including; an injecting member; a first syringe configured to provide the liquid medication; a second syringe configured to receive the liquid medication from the first syringe and move the liquid medication to the injecting member for patient delivery; and an accumulator configured to receive a portion of the liquid medication and to agitate the liquid medication back and forth between the accumulator and the second syringe, the accumulator being biased to an empty position; transferring the liquid medication from the first syringe to the second syringe; shuttling the liquid medication back and forth between the second syringe and the biased accumulator; and transferring the liquid medication from the second syringe to the injecting member for patient delivery. - View Dependent Claims (19, 20)
