Abstract: An injector system for delivering a medical fluid, the injector system including an injector configured to receive at least one syringe, the injector comprising at least one piston for releasably engaging and reciprocally driving a plunger or an end wall of the at least one syringe; and a syringe retaining interface comprising one or more retaining elements configured to engage at least a portion of a distal end portion of the at least one syringe to limit movement of the at least one syringe in a distal direction relative to the injector as the medical fluid is delivered from the reservoir via distal movement of the at least one piston.

Abstract: An engagement mechanism associated with a reciprocally movable piston of a fluid injector is configured for releasably engaging an engagement portion at a proximal end of a rolling diaphragm syringe having a flexible sidewall configured for rolling upon itself when acted upon by the piston. The engagement mechanism has a plurality of engagement elements reversibly and pivotally movable about a pivot pin relative to the engagement portion of the syringe between a first position, where the plurality of engagement elements are disengaged from the engagement portion of the syringe, and a second position, where the plurality of engagement elements are pivotally movable about the pivot pin in a radially inward direction to engage with the engagement portion of the syringe. The engagement mechanism further has a drive mechanism for moving the plurality of engagement elements between the first position and the second position.

Abstract: A fluid container having a proximal end having an end wall, a distal end having an open-ended neck, and a sidewall extending between the proximal end and the distal end along a longitudinal axis is described. A localized crystallinity of a polymeric material of the fluid container of at least a first region of the fluid container is greater than a crystallinity of a polymeric material of the fluid container of at least a second region. Examples of fluid containers include medical fluid containers, such as medical bottles and syringes, including rolling diaphragm-type syringes, and commercial beverage containers Articles of manufacturer formed form a polymeric material and having regions with increased localized polymeric crystallinity are also described.

Abstract: A syringe for a fluid delivery system includes a pressure jacket having a distal end, a proximal end, and a throughbore therebetween. The syringe further includes a rolling diaphragm having a proximal end with an end wall for engaging a plunger, a distal end received within the throughbore of the pressure jacket. The distal end of the rolling diaphragm has a nozzle and a sidewall extending between the proximal end and the distal end of the rolling diaphragm along a longitudinal axis. At least a portion of one of the sidewall and the end wall has non-uniform thickness. At least a portion of the sidewall is flexible and rolls upon itself when acted upon by the plunger such that an outer surface of the sidewall at a folding region is folded in a radially inward direction as the plunger is advanced from the proximal end to the distal end of the rolling diaphragm.

Abstract: A rolling diaphragm syringe includes a proximal end having an end wall, a distal end having an open-ended discharge neck, a sidewall extending along a longitudinal axis, and a piston engagement portion protruding proximally from a central portion of the end wall and configured for engagement with a piston of a fluid injector. The piston engagement portion has a stem with a first end attached to the end wall, a second end extending proximally from the first end, and at least one protrusion that protrudes radially outward. The sidewall is flexible and rolls upon itself when acted upon by the piston such that an outer surface of the sidewall is folded in a radially inward direction as the piston is advanced from the proximal end to the distal end, and unfolded in a radially outward direction as the piston is retracted from the distal end to the proximal end.
