1. A front loading syringe for use with an injector comprising a syringe retaining mechanism, the syringe comprising:
- a body comprising a rear end and a front end;
a plunger movably disposed within the body; and
at least one attachment member associated with the body, the at least one attachment member adapted to releasably engage the syringe retaining mechanism of the injector regardless of the orientation of the syringe about the axis of the syringe with respect to the injector.

Abstract
Embodiments of an injector, syringe, syringe interface, and piston/plunger assembly for an injector (of contrast medium, for example) are described. Preferably, the syringe is adapted to engage a syringe interface mechanism such that the syringe may be connected to an injector without regard to any particular orientation of the syringe to the injector or to the piston/plunger assembly.

16. A syringe for use with an injector comprising a syringe retaining mechanism including a flexible ring, the syringe comprising:
-
a body comprising a rearward end and a forward end;
a plunger movably disposed within the body;
at least one attachment member associated with the body, the attachment member cooperating with the flexible ring of the syringe retaining mechanism to releasably attach the syringe to the injector; and
at least one release member associated with the body, the release member operable to cause deformation of the flexible ring to enable release of the syringe from attachment with the injector upon rotation of the syringe about its axis relative to the injector. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)

29. A front loading syringe for use with an injector comprising a syringe retaining mechanism, the syringe comprising:
-
a body comprising a rear end and a front end;
a plunger movably disposed within the body;
at least one attachment member associated with the body, the at least one attachment member including an attachment flange extending around the entire perimeter of the syringe to releasably engage the syringe retaining mechanism of the injector regardless of the orientation of the syringe about the axis of the syringe with respect to the injector; and
at least one release member associated with the body, the release member interacting with the syringe retaining mechanism to enable release of the syringe from attachment with the injector upon rotation of the syringe about its axis relative to the injector. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36, 37, 38, 39)

40. A front loading syringe for use with an injector comprising a syringe retaining mechanism comprising an opening in the front of the injector, the syringe comprising:
-
a body comprising a rear end and a front end;
a plunger movably disposed within the body; and
at least one attachment member associated with the body, the at least one attachment member adapted to allow the syringe to be fully seated in a rearward axial direction within the opening lug of the retaining mechanism of the injector regardless of the orientation of the syringe about the axis of the syringe with respect to the injector. - View Dependent Claims (41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52)

53. A front loading syringe for use with an injector comprising a syringe retaining mechanism, the syringe comprising:
-
a body comprising a rear end and a front end;
a plunger movably disposed within the body;
at least one attachment member associated with the rear end of the body, the at least one attachment member including an attachment flange extending round the perimeter of the syringe to releasably engage the syringe retaining mechanism of the injector regardless of the orientation of the syringe about the axis of the syringe with respect to the injector;
at least one release member associated with the body, the release member interacting with the syringe retaining mechanism to enable release of the syringe from attachment with the injector upon rotation of the syringe about its axis relative to the injector; and
a flange associated with the body at a position forward of the at least one attachment member, the flange adapted to contact a corresponding surface of the injector when the syringe is releasably engaged therewith.
