Abstract: A connector assembly may include a body and a fluid fitting, the fluid fitting configured for releasably engaging a syringe nozzle, at least one deflectable locking arm connected to the body and radially deflectable relative to the distal end, the proximal end of the at least one deflectable locking arm configured for deflecting in a radial direction relative to the distal end to releasably engage the syringe nozzle, and at least one locking element disposed on the at least one deflectable locking arm, the at least one locking element movable with movement of the at least one deflectable locking arm between a first position where the at least one locking element is released from an engagement portion of the syringe nozzle and a second position where the at least one locking element is engaged with the engagement portion of the syringe nozzle.

Abstract: A syringe 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 barrel is formed from an injection molding process including aligning a mold die defining an internal shape of the barrel in a molding cavity defining an external shape of the barrel, the molding cavity defined by first and second mold sections. Each mold section includes at least one gate adapted to control the flow of a molding material into the molding cavity. The gates of each mold section are opened to permit the first and second melt streams of molding material to fill the molding cavity surrounding the mold die, where the molding material takes the shape of the molding cavity.

Abstract: A fluid injector system for delivering a multi-phase fluid injection to a patient and methods of fluid delivery is disclosed. Methods of creating and using a multi-aspect fluid path impedance model of the injector system are used. Modeling and adjustment of factors that affect impedance and prevent or reduce backflow, reduce the likelihood of fluid flow rate spikes and provide more accurate flow rates and mixing ratios of fluids may be repeated or happen essentially continuously during an injection. The adjustments may be determined before the injection or determined and/or adjusted during the injection. The determination may include sensor feedback commonly used in injectors such as pressure and position feedback as well as other sensors. In all cases, the user can be notified of adjustments through on-screen notices and/or through the recordation of the injection data by a control device of the injector at the conclusion of the injection.
