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 pressure jacket configured for connecting to an injector head of a fluid injector has an open distal end, an open proximal end, and a sidewall defining a throughbore extending between the distal end and the proximal end along a longitudinal axis. The throughbore is configured for receiving at least a portion of a syringe. The pressure jacket has at least one syringe retaining element positioned at least partially within the throughbore. The at least one syringe retaining element is configured for engaging at least a portion of the syringe during pressurized delivery of fluid from the syringe to prevent or limit a distal movement of the syringe relative to the pressure jacket.

Abstract: A single-use connector configured to be removably connected to a reusable connector includes a hollow, tubular housing having an open proximal side opposite a distal side along a longitudinal length of the housing and at least one guard member connected to the tubular housing. The at least one guard member is configured to transition between an open position, in which the single-use connector can be connected to the reusable connector, and a closed position in which the guard member prevents the single-use connector from being connected to the reusable connector. Disconnecting the single-use connector from the reusable connector causes the at least one guard member to transition from the open position to the closed position. A single-use disposable set (SUDS) including a single-use connector and at least use guard member for preventing reconnection of the connector to a reusable connector or fluid port is also disclosed.

Abstract: A system for heating a medical fluid has at least one first fluid container for storing the fluid, a fluid injector having at least one second fluid container for receiving the fluid from the at least one first fluid container through a fluid path set, at least one heating element positioned in-line with the fluid path set between the at least one first fluid container and the at least one second fluid container of the fluid injector for heating the fluid to a pre-determined temperature as the fluid flows through at least one fluid path element, and a controller for controlling an output of the at least one heating element based on at least one of a property of the at least one heating element and a property of the fluid flowing through the at least one fluid path element.

Abstract: A plunger for use with a syringe has a plunger body with a proximal end, a distal end, and a circumferential sidewall extending between the proximal end and the distal end along a plunger longitudinal axis. The plunger further has at least one resiliently deflectable retaining member having a first segment attached to the plunger body and a second segment protruding toward the distal end of the plunger body and deflectable relative to the first segment. The plunger further has at least one actuation member associated with the at least one resiliently deflectable retaining member. The at least one actuation member interacts with a piston to deflect the at least one resiliently deflectable retaining member upon rotation of the plunger relative to the piston. The plunger is engageable with the piston regardless of a rotational orientation of the piston relative to the plunger.

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: 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 radially movable 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 engaged 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 medical injector including at least one syringe port for engaging at least one syringe and having a locking mechanism. The locking mechanism enables the syringe to self-align with the syringe port for locking engagement upon insertion of the syringe into the syringe port and to axially eject the syringe from the port upon rotational disengagement of the syringe from the port.
