A system and method for mixing and delivering fluids such as contrast media and saline is disclosed including at least two fluid sources, a pump, a joining fluid path connecting the at least two fluid sources to an inlet to the pump, and a valve device in the fluid path upstream of the pump. The valve device includes an actuator adapted to restrict flow in at least one of respective fluid lines connecting the at least two fluid sources to the pump inlet. A patient interface device may be associated with an outlet of the pump. The valve device actuator is generally adapted to restrict the flow in at least one of the respective fluid lines such that a positional change in valve device actuator position provides a change in fluid mixture ratio of the fluids from the at least two fluid sources to the pump inlet.

In one aspect, a system for delivery of a medical fluid to a patient includes a pump system including a plurality of at least three chambers. Each of the plurality of chambers includes an inlet through which fluid is drawn into the chamber and an outlet from which fluid is expelled from the chamber. The pump system further includes a common outlet channel in fluid communication with the outlet of each of the plurality of chambers and a plurality of at least three pistons. Each of the pistons is slidably disposed within a respective one of the plurality of chambers. The system further includes a drive system including a cam shaft including a plurality of at least three cam lobes. Each of the plurality of cam lobes has a profile. The drive system further includes a plurality of at least three cam lobe followers. Each of the cam lobe followers is in operative connection with a respective one of the plurality of cam lobes and is adapted to be placed in operative connection with a respective one of the plurality of pistons. The profile of each of the plurality of cam lobes is adapted to provide a transient increase or spike in calculated theoretical output of the pump system to reduce periodic variation in measured output thereof.

Disclosed are several embodiments of an electrode system for ventricular defibrillation, and the methods of using and implanting the electrode system. In one embodiment, the electrodes are in a generally base-apex configuration having a split conformal base electrode residing above the base of the ventricles (a transecting plane separating the atria from the ventricles) in the region of the atria and a conformal apex electrode in the form of a rotated conic section residing at the apex of the heart. In another embodiment, defibrillation is accomplished by the apex electrode acting against a catheter electrode situated high in the heart or in the superior vena cava. The electrodes themselves are in the form of planar metallic mesh elements adapted to lie in contact with body tissue on an active surface, insulated on the opposite surface. In another embodiment, the conductive portions of the respective electrodes are developed from metallic plates, exposed on one surface and insulated on the other. The electrodes may be split, or may entirely surround the base and apex of the heart.

A system for delivery of a medical fluid to a patient includes a pump system including a pressurizing unit to pressurize the medical fluid and a drive system in operative connection with the pressurizing unit. The pump system exhibits variation in pressure during operation. The system further includes a compensating system in fluid connection with the medical fluid pressurized by the pressurizing unit. The compensating system defines a displacement volume in fluid connection with the pressurized medical fluid that is altered in a predetermined manner to alter the variation in pressure. The compensating system can, for example, reduce pulsatility of pressure during flow.

A cardiovascular flow system includes: a cardiovascular model system, a pump system in fluid connection with the cardiovascular model system, and an ECG simulator in communicative connection with the pump system. The ECG simulator system is adapted to create and transmit a simulated ECG signal. The ECG simulator system uses a signal received from the pump system to adjust the simulated ECG signal transmitted from the ECG simulator system. The cardiovascular flow system further includes an injection port adapted to be placed in fluid connection with an injector to inject at least one fluid into the system.

A system for delivering a slurry to a patient includes a fluid, a material that is non-dissolvable or immiscible in the fluid, thereby forming a slurry, a container adapted to contain the slurry and a supernate of the slurry, the container defining an outlet through which the slurry is delivered to the patient, a fluidizing system associated with the container, a pressurizing mechanism adapted to create a pressure to cause the slurry contained within the container to flow for delivery to the patient and a control unit in communication with and adapted to control the fluidizing system and the pressurizing mechanism. The fluidizing system is adapted to effect dilation of the slurry while maintaining at least a portion of the supernate.
