A fluid injection system includes a valve device and a valve actuation device. The valve device has a valve member and a valve member coupling. The valve member has an open position that permits fluid to pass through and a closed position that prevents fluid from passing through. The valve member coupling is configured, when actuated, to transition the valve member between the open and closed positions. The valve actuation device having a valve actuation coupling and a drive mechanism. The valve actuation coupling is coupled to the valve member coupling and drive mechanism. The valve actuation coupling is movable independent of the drive mechanism to couple the valve actuation coupling to the valve member coupling. And, the valve actuation coupling is movable with the drive mechanism to actuate the valve member coupling to transition the valve member between the open and closed positions.

A method is provided for manufacturing a polymer-coated elastic braid including forming a plurality of elastic filaments into a braid. The braid is mounted within a tubular mandrel. The mandrel-mounted braid is dip-coating in a polymer solution containing a polymer and at least one solvent. The dip-coated braid is then heated to release the at least one solvent. Then, the dip-coated mandrel-mounted braid is cooled to solidify the polymer on the braid. The braid is then removed from the mandrel. The braid can be attached to a catheter for use as a microvalve in a vessel.

An exemplary compounding system and method can include a transfer set that includes a manifold for assisting in transferring a plurality of ingredients from supply container(s) to a final container. The manifold can include a first channel in fluid communication with at least one primary ingredient, and a second channel in fluid communication with a plurality of secondary ingredients. The first channel and second channel can be in fluid isolation from each other such that the at least one primary ingredient does not mix with the plurality of secondary ingredients within the manifold. The transfer set can include a plurality of inlet lines in fluid communication with the manifold and two outlet lines configured for connection to two separate pumps and eventually being in fluid communication with the final container.

An exemplary compounding system and method can include two pump heads for simultaneously drawing two different fluids from at least two separate input containers such that the at least two different fluids are mixed and distributed to an output container. The system can include a manifold that maintains separation of certain of the different fluids until after passing by a first pump and a second pump and/or additional pumps. A junction can be placed in the fluid line downstream of the first and second pumps and/or additional pumps such that all or some of the fluids are mixed prior to output to the output container. The method of using the system can include incorporating software that selects various fluids at certain times and sequences to ensure optimum efficiency and safety for the system, and can continue compounding actions even when an input supply container runs out or otherwise fails to supply a particular fluid/material. The method of use also includes connection of a transfer set to a housing in a manner that further ensures optimum efficiency and safety.

A method for using CO.sub.2 as a contrast material in medical imaging procedures is disclosed. The method includes providing a source of pressurized CO.sub.2. The step of providing includes connecting the source of pressurized CO2 to a compressed gas unit for controlling delivery of the CO.sub.2. The method also includes regulating pressure of the CO.sub.2 delivered by the compressed gas unit, transmitting the pressurized CO.sub.2 from the compressed gas unit to a control valve assembly for delivery to a patient in controlled dosages, and sequentially processing the CO.sub.2 with the control valve assembly and delivering the CO.sub.2 to the patient as a contrast media.

A vacuum aspiration system may be used to treat thromboembolic disease, such as deep vein thrombosis or pulmonary embolism. The system includes a housing, and a fluid flow path extending through the housing. A first catheter is in fluid communication with the flow path, and a connector is configured to place a source of aspiration in communication with the flow path. A clot container is carried by the housing. A hemostasis valve is provided in the housing, and configured to receive a second catheter and direct the second catheter through the first catheter.

Fluid manifolds are described herein. A fluid manifold includes a manifold body and a valve. The manifold body defines an inlet port, an outlet port, a flow channel, and a divider volume. The flow channel is in fluid communication with the inlet port and the outlet port. The divider volume is in fluid communication with the injection port and the flow channel. The valve includes a divider body. The divider body is movable within the divider volume. The divider body defines a divider port. The divider body can be moved to restrict or prevent flow from the injection port to the flow channel in a first position. The divider port can permit flow from the injection port to the flow channel in the second position of the divider body.

A catheter holder includes an attachment section configured to be attachable to a holder tube that accommodates at least a portion of a sheath of an image diagnosis catheter in a wound state, a support section extending from the attachment section in a direction away from the wound holder tube, and a fixing section provided on a second end side of the support section, which is opposite to a first end side of the support section on which the attachment section is provided, and configured to fix a unit connector and a hub of the image diagnosis catheter to hold the outer tube, which is exposed from an opening portion of the holder tube, in a linear shape to be fixed in position.

A delivery system for the delivery of embolic agents to a patient includes a control valve assembly interconnecting first, second, third and fourth conduits, wherein the control valve assembly selectively moves between first, second, and third states under the control of a medical professional. In the first state, the first conduit communicates with the second conduit for transmitting a solution of embolic agents between a first syringe secured to the first conduit and a second syringe secured to the second conduit. In the second state, the second conduit communicates with the third conduit for transmitting the solution of embolic agents from the second syringe to a delivery catheter secured to the third conduit. In the third state, the third conduit communicates with the fourth conduit for flushing the delivery catheter via a third syringe, which is filled with saline, connected to the fourth conduit.

A holding device (1) for automated stopcock actuation, comprising a base body (2); and a driver (3) rotatably received at the base body (2). The holding device (1) has a receptacle (4) for removably receiving at least a part of a stopcock (A) and is configured such that the driver (3) can engage with and actuate a handle (B) of the stopcock (A) received in the receptacle (4) upon rotation of the driver (3), and a first fixation member (5) that is configured to allow selective fixation of the stopcock (A) in the receptacle (4).
