摘要： A stopper adapted for attachment with a plunger rod for use within a syringe barrel includes a main body portion defining an open rearward end configured to receive the plunger rod. The main body portion is manufactured from a rigid or semi-rigid polymeric material having an elastic modulus in the range of about 0.01 GPa to about 5 GPa. When fluid pressure is increased inside the syringe barrel during an injection, at least one of the following actions occurs: a) a flexible roof of the main body portion expands in a radial direction toward an inner wall of the syringe barrel; b) a first perimetrical skirt extending around an outer circumference of the main body portion is forced against an inner wall of the syringe barrel; and c) an engagement between the plunger rod and an engagement portion provided along an inner circumference of the main body portion.

摘要： A stopper includes a main body portion defining an open rearward end configured to receive the plunger rod, an engagement portion provided along an inner circumference of the main body portion configured to engage at least a top portion of the plunger rod, a closed front end forming a flexible roof, and a first perimetrical skirt extending around an outer circumference of the main body portion toward the closed front end of the main body portion. When fluid pressure is increased inside the syringe barrel during an injection, the flexible roof expands in a radial direction toward an inner wall of the syringe barrel, the first perimetrical skirt is forced against the inner wall of the syringe barrel, and an engagement between the plunger rod and the engagement portion forces the main body portion to expand in the radial direction toward the inner wall of the syringe barrel.

摘要： 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 cathether 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.
