Abstract:
Flush syringe assemblies capable of creating pulsatile movement of the plunger rod as it moves in the distal direction within a syringe barrel, while preventing overpressurization of the catheter are provided. An exemplary flush syringe assembly includes a syringe barrel with a first pulsing element and a chamber with flush solution, a plunger rod with a stopper and a second pulsing element that interacts with the first pulsing element to provide an engagement force that causes pulsatile movement of the plunger rod and a thumb press slidably attached to the plunger rod with a pulse control element. The pulse control element is compressible to create a compression force that is greater than the engagement force of the first pulsing element and the second pulsing element.

Claim (Index 1):
A flush syringe assembly comprising:\n a barrel including a side wall having an inside surface defining a chamber for retaining fluid, an open proximal end and a distal end including a distal wall with a tip extending distally therefrom and having a passageway therethrough in fluid communication with the chamber, the barrel comprising a first pulsing element on the inside surface of the barrel; a plunger rod disposed within the barrel, the plunger rod comprising a distal end, a proximal end, a plunger rod body extending from the distal end to the proximal end and having a second pulsing element; a thumb press slidably attached to the proximal end of the plunger rod; a pulse control element disposed between the thumb press and the proximal end of the plunger rod; and a stopper disposed at the distal end of the plunger rod to form a fluid-tight seal with the inside surface of the barrel, wherein in a first position, the second pulsing element engages the first pulsing element to provide an engagement force that resists distally directed force applied to the plunger rod, and force applied to the thumb press in the distal direction exceeds the engagement force to cause pulsatile movement of the plunger rod as it moves within the barrel in the distal direction; and in a second position, upon rotation of the plunger rod to prevent the second pulsing element from engaging with the first pulsing element, there is continuous movement of the plunger rod as it moves within the barrel in the distal direction.
