    Abstract: A syringe system and components thereof are disclosed. The system may include a syringe body having a hollow lumen, a proximal open end, and a distal end. The syringe body may be configured to house a fluid therein. The syringe system may further include a plunger positioned in the hollow lumen of the syringe body, forming a seal with an inner wall of the syringe body. The plunger may include a removable piston having a shaft extending from the distal end towards the proximal open end, a stopper removably connected to a distal portion of the shaft, and at least one coupler attached to the distal portion of the shaft. The stopper may be configured to slidably move within the hollow lumen to facilitate movement of the fluid within the syringe body. The coupler may be configured to facilitate removal and attachment of the stopper from the piston.

    Abstract: A pressure jacket includes a barrel having a proximal end, a distal end, and a sidewall extending substantially circumferentially between the proximal end and the distal end along a longitudinal axis. The pressure jacket also includes at least one retaining member having at least one first lug protruding radially outward relative to an outer surface of the sidewall. The at least one first lug has at least one third surface tapered axially relative to the longitudinal axis of the barrel in a proximal direction. The at least one first lug is configured for engagement with a locking mechanism associated with a port on a fluid injector to releasably lock the pressure jacket with the fluid injector. At least a portion of the at least one third surface axially ejects the pressure jacket upon rotation of the pressure jacket about the longitudinal axis.

    Abstract: Systems and methods for intelligently delivering fluid to a targeted tissue are described. The systems and methods may include directing a pump to distribute fluid to a targeted tissue and receiving one or more signals from an intracorporeal sensing system, where the one or more signals correspond to one or more sensed feedback parameters at the targeted tissue. The systems and methods may also include determining whether the one or more sensed feedback parameters are within an acceptable range. If the one or more sensed feedback parameters are not within the acceptable range, the systems and methods may include determining an adjusted velocity for the plunger necessary to adjust the pressure of the fluid in the pump so that the one or more sensed feedback parameters move within the acceptable range and directing the pump to distribute the fluid at the adjusted velocity

    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.
