1. A 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 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.

40. An injector system comprising an injector and a syringe, the injector system comprising:
-
a syringe comprising;
a body comprising a forward end and a rearward end; and
a plunger movably disposed in the body; and
an injector comprising;
a housing; and
a piston movably disposed at least partially within the housing and operable to drive the plunger of the syringe in a forward direction without a connective engagement therebetween to dispense fluid from the forward end of the body during an injection procedure, wherein the piston connectively engages the plunger to retract the plunger within the syringe. - View Dependent Claims (41, 42, 43, 44, 45, 46)
