Abstract

A syringe including a syringe body extending from a proximal end to a distal end, and a stabilizing element provided on the distal end of the syringe body, a portion of the stabilizing element extending substantially perpendicular to a longitudinal axis of the syringe body. A multi-use disposable set (MUDS) includes a plurality of syringes, each syringe having a syringe body, a proximal end, a distal end spaced apart from the proximal end along a longitudinal axis of the syringe body, a stabilizing element provided on the distal end, a portion of the stabilizing element extending substantially perpendicular to the longitudinal axis of the syringe body, and a manifold in fluid communication with the distal end of each of the plurality of syringes.

First claim

1 - 20 . (canceled)

21 . A syringe, comprising:
a syringe body having a proximal end and a distal end spaced apart from the proximal end along a longitudinal axis of the syringe body; a cone portion and a nozzle extending distally from the distal end of the syringe body; and a stabilizing element provided on a proximal end of the cone portion of the syringe body, wherein the stabilizing element has a support surface extending substantially perpendicular to the longitudinal axis of the syringe body for providing stable vertical alignment of the syringe with a movable piston element of a fluid injector as a planar surface on a plate of the fluid injector contacts the stabilizing element; wherein the proximal end of the syringe body interacts with a bottom plate of the fluid injector to align the syringe in a receiving space of the fluid injector.

22 . The syringe of claim 21 , wherein the stabilizing element is integrally formed on the syringe body.

23 . The syringe of claim 21 , wherein the stabilizing element comprises a ring provided on an outer circumferential surface of the distal end of the syringe body.

24 . The syringe of claim 21 , wherein the stabilizing element comprises a sleeve having a planar upper support surface extending substantially perpendicular to the longitudinal axis of the syringe and provided on an outer circumferential surface of the syringe body, the sleeve extending from the proximal end of the syringe body to the distal end of the syringe body.

25 . The syringe of claim 21 , wherein the stabilizing element comprises a portion of the syringe body that extends axially along a longitudinal axis of the syringe body to form a planar upper support surface extending substantially perpendicular to the longitudinal axis and protrudes from the cone portion on a distal end of the syringe body.

26 . The syringe of claim 21 , wherein the stabilizing element comprises a planar portion and at least two webs connected to the cone portion and the planar portion.

27 . The syringe of claim 21 , wherein the stabilizing element comprises at least two substantially triangular extensions including an upper planar surface and a bottom surface connected to the cone portion.

28 . The syringe of claim 27 , wherein the upper planar surface extends substantially perpendicularly relative to the longitudinal axis of the syringe body.

29 . The syringe of claim 21 ,
wherein the stabilizing element comprises a first planar portion connected to the cone portion via at least one web, and a second planar portion connected to the cone portion via at least one second web, and wherein the planar portions are separated from one another on the cone portion.

30 . The syringe of claim 29 ,
wherein the planar portions extend substantially perpendicularly relative to the longitudinal axis of the syringe body, and wherein the planar portions are positioned adjacent to a discharge conduit defined in the distal end of the syringe body.

31 . A multi-use disposable set (MUDS) comprising:
a plurality of syringes, each syringe having a syringe body, a proximal end, a distal end spaced apart from the proximal end along a longitudinal axis of the syringe body, a cone portion and a nozzle extending distally from the distal end of the syringe body, and a stabilizing element provided on the distal end of the syringe body, the cone portion being monolithically formed with the syringe body, the stabilizing element comprising a continuous ring that extends around an entire outer circumferential surface of a proximal end of the cone portion on the distal end, the stabilizing element having an engagement surface extending substantially perpendicular to the longitudinal axis of the syringe body, wherein the engagement surface is configured to stabilize a vertical alignment of each syringe of the plurality of syringes when a planar surface of a top plate of a fluid injector system defining at least one syringe slot is moved into a closed position to contact the engagement surface of each of the syringes, wherein an outer diameter of the stabilizing element is greater than an outer diameter of the syringe body, and wherein the stabilizing element is integrally formed on the syringe body; a frame for receiving at least a portion of the proximal end of each syringe of the plurality of syringes and for interacting with a bottom guide of the fluid injector to align the MUDS in a receiving space of the fluid injector; and a manifold in fluid communication with the distal end of each syringe of the plurality of syringes.

32 . The MUDS of claim 31 , wherein the stabilizing element comprises a sleeve provided on an outer circumferential surface of the syringe body, the sleeve extending from the proximal end of the cone portion of the syringe body to the distal end of the syringe body.

33 . The MUDS of claim 31 , wherein the stabilizing element comprises a portion of the syringe body that extends axially along a longitudinal axis of the syringe body and protrudes from the cone portion on a distal end of the syringe body.

34 . The MUDS of claim 31 , wherein the stabilizing element comprises a planar portion and at least two webs connected to the cone portion and the planar portion.

35 . The MUDS of claim 31 , wherein the stabilizing element comprises at least two substantially triangular extensions including an upper planar surface comprising a portion of the ring and a bottom surface connected to the cone portion.

36 . The MUDS of claim 35 , wherein the upper planar surface extends substantially perpendicularly relative to the longitudinal axis of the syringe body.

37 . The MUDS of claim 35 ,
wherein the stabilizing element comprises a first planar portion connected to the cone portion via at least one web, and a second planar portion connected to the cone portion via at least one web, and wherein the planar portions are separated from one another on the cone portion.

38 . The MUDS of claim 37 ,
wherein the planar portions extend substantially perpendicularly relative to the longitudinal axis of the syringe body, and wherein the planar portions are positioned adjacent to a discharge conduit defined in the distal end of the syringe body.
