Abstract:
1. An ultrasonic suspension delivery device, comprising: a barrel including a proximal opening and a distal opening coupled to a delivery mechanism; and an ultrasonic resonating syringe plunger, slidingly displaceable within the barrel for pushing a liquid toward the distal opening of the barrel, including: a front body including a bore extending completely therethrough, and a seal, disposed along the outer circumference of the distal end, to engage the inner surface of the barrel, a rear body including a bore extending partially therethrough, a proximal end having a transverse plunger surface, and a distal end attached to the proximal end of the front body, a transducer disposed within the bore of the rear body, a horn agitator, disposed within the bore of the front body, rigidly coupled to the transducer and resiliently coupled to the front body, and at least one power connector, coupled to the transducer, to receive power from an ultrasonic energy source.
