Abstract: A plunger for use with a syringe includes a plunger body defining a central longitudinal axis and having a proximal end, a distal end, and a circumferential sidewall connecting the proximal end and the distal end. The plunger further includes at least one retaining member associated with and extending proximally from the plunger body. The at least one retaining member has a first end connected to the plunger body, a second end proximal to the first end and radially and resiliently deflectable relative to the first end, and at least one catch on the second end. A fluid injector system includes a piston having a plunger engagement mechanism configured for interacting with the at least one retaining element of the plunger to releasably engage the plunger for reciprocally driving the plunger within a barrel of the syringe.

Abstract: A multi-fluid injector system having a powered injector having a housing enclosing at least one reciprocally operable piston is described. The injector system includes a multi-use disposable set (MUDS) connectable to the powered fluid injector. The MUDS has at least one syringe having a proximal end and a distal end and a plunger reciprocally movable by the at least one piston element within a syringe interior between the proximal end and the distal end; a manifold in fluid communication with the distal end of the at least one syringe; at least one valve in fluid communication with the syringe interior, the at least one valve operable between a filling position for filling the syringe interior with fluid and a delivery position for delivering the fluid from the syringe interior; and at least one connection port in fluid communication with the manifold and the syringe interior when the at least one valve is in the delivery position. The injector system further includes a coupling mechanism for operating the at least one valve between the filling position and the delivery position. Various features of the MUDS assembly and methods of interaction between the injector system and the MUDS assembly are also described.

Abstract: A system capable of monitoring a replaceable component is provided. The system includes a controller for controlling operation of the system; programming instructions according to which the system is configured to: accept input of a viable life for the component, calculate an accumulated amount of distress experienced by the component based on each set of previously collected use data associated with each previous use of the component, and determine, based in part on the accumulated amount of distress, a used portion of the viable life that the component has experienced as a result of the previous use(s) thereof and an unused portion of the viable life; and a feedback device configured to provide to an operator of the system an indication of at least one of the unused and used portions of the viable life of the component. Methods of monitoring a replaceable component of a system are also provided.
