摘要： An adapter includes a syringe carrier adapted to seat at least a portion of the syringe. The syringe carrier includes at least one rearward facing abutmer member to abut at least one forward facing surface on a syringe. The syringe carrie includes an opening therein to allow a drive member of an injector to communicate forward force to the plunger through abutment without connective engagement between the drive member and the plunger. The adapter further includes a releasable mounting mechanism positioned to the rear of the syringe carrier to mount the adapter in a desired position relative to the front wall of the injector. An adapter includes a first section and a second section that are rotatable relative to each other about a hinge axis generally perpendicular to a longitudinal axis of the adapter. An adapter includes a first section and a second section that are generally the same in construction, the first section and the section being connectable to form a syringe carrier to seat at least a portion of the syringe.

摘要： A fluid delivery system which includes a pressurizing device for delivering injection fluid under pressure, a low pressure fluid delivery system, and a pressure isolation mechanism. The pressure isolation mechanism includes a valve housing having a first port associated with the pressurizing device, a second port associated with the low pressure fluid delivery system, an outlet port associated with a patient, and a pressure isolation port for connection with a pressure transducer. A first valve in a normally open position permits fluid communication between the first port and the second port and is movable to a closed position when fluid pressure in the first port increases to a predetermined pressure level. The first valve isolates the pressure isolation port from the first port when in the closed position. A second valve is associated with the second port and regulates fluid flow through the second port.

摘要： A syringe interface or adapter includes a first retaining member that pivots about an axis generally perpendicular to and offset from the axis of an injector piston when the syringe interface is attached to the injector. The first retaining member pivots in a rearward direction to engage a portion of the syringe flange. The syringe interface further includes a second retaining member slideably positioned within a passage in the syringe interface to slide in a direction generally perpendicular to the axis of the piston when the syringe interface is attached to the injector to engage a portion of the syringe flange. The first retaining member and the second retaining member preferably cooperate to engage the syringe flange around the entire perimeter of the syringe flange. The first retaining member is preferably biased toward an open position. The syringe interface can also include a rear portion having an attachment mechanism to attach the syringe interface to the injector.

摘要： A method of determining fractional flow reserve (FFR) in a blood vessel having stenosis includes injecting fluid into the blood vessel upstream of the stenosis using a power fluid injector, measuring pressure drop across the stenosis, and calculating FFR from measured pressure drop. The injected fluid may comprise a contrast medium. Further actions may include placing a pressure sensor proximal of the stenosis, injecting fluid into the blood vessel upstream of the stenosis using the power fluid injector, and measuring pressure in the blood vessel proximal of the stenosis. The pressure sensor may then be repositioned to a position distal of the stenosis, fluid may be reinjected into the blood vessel upstream of the stenosis using the power fluid injector, and pressure may be measured in the blood vessel distal of the stenosis.

摘要： An insertable intracavity probe for use in magnetic resonance imaging of an area of interest in a relatively inaccessible region of the body is disclosed. The probe has an internal pickup coil carried at the distal end of a shaft for rectal insertion of the coil and an inflatable anti-migration cuff to hold the probe in position and prevent outward migration thereof during a procedure. The anti-migration cuff is carried on an outer sleeve which is slidably and rotatably mounted on the shaft. The coil is carried on a resilient tip structure at the distal end of the shaft which is flexible in the plane normal to the plane of the coil. Deflection of the coil assembly is controlled by a pair of control lines attached to the distal end of the tip structure. The lines may be selectively tensioned to deflect the coil in the direction of tension by a thumb wheel control at the handle of the probe.

摘要： A fluid path for use in a fluid delivery system is described. The fluid path may have a connecter member having a lumen, a luer member connected to the lumen, and an annular member around the luer member. The fluid path may further have a check valve in the lumen to limit fluid flow in one direction. The check valve may have a deformable stopper element and a retaining sleeve disposed in the lumen of the connecter member. The retaining sleeve may have a central bore and a distal end against which the stopper element sits to prevent fluid flow through the lumen until a sufficient fluid pressure is present to deform the stopper element and unseat the stopper from the retaining sleeve. One or more grooves may be present in the receiving cavity. The fluid path may further have a drip chamber, a second tubing section, and a spike.

The syringe has a cylindrical body with an injection section at a distal end and a plurality of outward extending retaining flanges at a proximal end. The injector has an injector housing defining a central opening and an injector drive piston extendable through the central opening for imparting motive forces to a syringe plunger disposed within the syringe. The pressure jacket secures the syringe during an injection procedure. The pressure jacket has a wall defining a plurality of longitudinally extending grooves in an inner surface thereof configured to receive the retaining flanges of the syringe. The grooves cooperate with a plurality of transversely extending slots defined in the inner surface of the pressure jacket wall. The engagement of the retaining flanges in the slots via the grooves secures the syringe in the pressure jacket.
