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.

In one aspect, a valve includes an interior channel for permitting a fluid to flow through the valve and an opening to the interior channel, the opening including a circular portion and a tapered portion adjacent the circular portion, the tapered portion having a maximum width that is less than a diameter of the circular portion, wherein the valve is rotatable about a central axis of the valve to adjust a position of a cross-sectional area of the opening with respect to a cross-sectional area of an inlet fluid line positioned to deliver the fluid to the rotary valve.

A medical stopcock assembly with position detection includes a medical stopcock and a sensor. The medical stopcock may include a main body and a valve body. The valve body may define a valve passageway and be moveable relative to the main body between a first position where a first input port and an output port are in fluid communication via the valve passageway, a second position where a second input port and the output port are in fluid communication via the valve passageway, and a third position where the second input port and the first input port are in fluid communication via the valve passageway. An external surface of the valve body may include a position structure. The sensor may be configured to sense the position structure to determine whether the valve body is in the first position, the second position, or the third position.

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 pump set for use with a pumping apparatus includes tubing for carrying a liquid. A valve mechanism is mounted to the tubing between an inlet section and a pump engagement section. The valve mechanism includes a first port connected to the inlet section of the tubing, a second port connected to the pump engagement section of the tubing, and a valve disposed between the first and second ports. The valve includes a stem rotatably mounted within a stem holder. The stem includes a flow passage extending through the stem and having an open V shape whereby a narrow open end of the flow passage communicates with the first port and a wide open end of the flow passage communicates with the second port to place the inlet section of the tubing in communication with the pump engagement section of the tubing.

A patency checking system, may include a fluid path to be coupled to an intravenous (IV) device at a distal end of the fluid path; a patency port formed along a length of the fluid path; and a plunger fluidically coupled to the fluid path at the patency port to selectively draw blood into the fluid path to confirm patency of the fluid path.

A fluid distribution system for delivering fluid internally of a body comprises a hollow needle and an implantable access port. The needle has a tip with a predetermined shape. The access port includes (a) a housing that includes at least two fluid outlets, (b) a septum received in the housing, and (c) a valve member rotatable in the housing. The valve member includes valve fluid inlet and outlet openings and a valve inlet passage extending from the inlet opening to the outlet opening. The valve inlet passage has a shape complementary to the shape of the needle tip. The valve member is rotatable into (i) a first position in which the valve fluid outlet opening communicates with a first housing fluid outlet and (ii) a second position in which the valve fluid outlet opening communicates with a second housing fluid outlet.

A valve assembly for controlled drainage or delivery of a fluid from or to a patient including a first port (182), a second port (184), a diaphragm chamber and a diaphragm (132) dividing the diaphragm chamber into a first chamber cavity (158A) and a second chamber cavity (158B). The diaphragm being deflectable toward a first wall of the diaphragm chamber wherein the first chamber cavity contracts and the second chamber cavity expands, and oppositely toward a second wall of the diaphragm chamber wherein the second chamber cavity contracts and the first chamber cavity expands. A valve (212) is actuatable between a first actuation state that establishes fluid communication between the first port and the second chamber cavity and separately between the second port and the first chamber cavity. The valve also having a second actuation state that establishes fluid communication between the first port and the first chamber cavity, and separately between the second port and the second chamber cavity.

A medical device includes: a medicinal agent storage device connected to the catheter, a flow control device, and a package. The medicinal agent storage device includes a storage part and a second channel, the storage part is configured to store a medicinal agent, and wherein the second channel provides fluid communication between the storage part and the first channel. The package encloses the catheter, the medicinal agent storage device, and the flow control device in a sterilized state. In a first state, the flow control device is configured to prevent the medicinal agent from flowing from the storage part into the first channel. The flow control device is included in the catheter or included in the medicinal agent storage device.

The package comprises a sterile bag (3) filled with liquid diluent, a bottle (9) equipped with a pierceable cap (26) to contain a medicinal or nutritional substance and a tube (12) extending from the bag and ending with a coupling and perforation device (16) for the cap of the bottle. Said bag is housed in a flexible sterile sealed casing (1), while the bottle and the coupling and perforation device are accommodated in a second flexible sterile sealed casing (2). The tube (12) has a portion (13) between the first and second casing, housing a flow diverter (18) adjustable from a first position in which it impedes any communication between the bottle and the bag, to a second position in which it allows the bag to be put in communication with a sealed side opening (19) for a syringe (22), or a third position in which it allows the bottle to be connected with said side opening. To another side opening (41) of the flow diverter a flexible tube (42) with hydrophobic filter (43) is attached, terminating into one and/or the other of said sterile sealed casings and serving as a pressure compensator.
