Valves are described for intravenous (IV) catheter assemblies for controlling fluidic flow. The valve can prevent blood leakage in multiple access use situations. A thinner area of the valve around a slit is provided. The thicker area of the valve is to provide rigidity to the valve so that it is able to return to a closed configuration when a Luer connector is removed.

A delivery catheter (12) for a stent valve (10), the delivery catheter having a distal portion (14) insertable into an anatomy, the distal portion comprising an accommodation region (18) for accommodating a stent-valve for delivery into the anatomy, the delivery catheter further comprising at least one sheath (20; 22) that is translatable between a closed position for at least partly closing the accommodation region and an open position for at least partly opening the accommodation region.

Embodiments herein include an insertion tool for inserting a medical device into another medical device, such as a hemostasis sealing valve, and related methods. In an embodiment, an insertion tool includes a guide sheath and a protection tube. The guide sheath can include a flared proximal end. The guide sheath can further include a central lumen. The guide sheath can further include a locking notch disposed on the inner surface between the proximal end and the distal end. The protection tube can include a flared proximal end. A portion of the protection tube can be situated within the central lumen of the guide sheath. The flared proximal end of the protection tube can be sized to fit within the locking notch and can have an outer diameter larger than portions of the inner surface immediately adjacent to the locking notch. Other embodiments are also included herein.

A lithotripsy device can comprise a handpiece, a lithotripsy probe extending from the handpiece, an energization source configured to deliver an energy to a distal end of the lithotripsy probe, a suction passage extending from the distal end of the probe and through the handpiece, and a capture device comprising a container comprising a storage space, an entry port configured to couple to the handpiece at the suction passage, and an exit port, and a capture element connected to the container and configured to facilitate capture of stone fragments within the storage space. A method can comprise fragmenting stones with a lithotripsy device, drawing a vacuum through the lithotripsy device to pull stone fragments and waste fluid therethrough, pulling the vacuum through a stone capture device connected to the lithotripsy device, depositing stone fragments within the stone capture device using a capture element, and drawing the vacuum through the device.

An intravenous catheter assembly comprises a catheter hub having an elongate axis and a lumen; a side port extending from the catheter hub, the side port being in fluid communication with the lumen; and a one-way port valve positioned in the side port, the one-way port valve having a valve portion formed from a resilient material. The valve portion can comprise a cap and a hinge portion about which the cap is rotatable. The cap can be disposed over an aperture formed in an inclined end face of the valve portion.

Certain aspects of the present disclosure provide a low friction trocar valve comprising a set of sheets arranged circularly and defining an entry point for the insertion of an instrument. In certain aspects, each sheet of the trocar valve's set of sheets comprises areas that overlap with two adjacent sheets. The trocar valve is formed in an opening of a valve housing coupled to or formed as part of a trocar cannula to provide a sealing mechanism for preventing the escape of pressurized fluids from the trocar cannula.

A delivery catheter for a stent valve, the delivery catheter having a distal portion insertable into an anatomy, the distal portion comprising an accommodation region for accommodating a stent-valve for delivery into the anatomy, the delivery catheter further comprising at least one sheath that is translatable between a closed position for at least partly closing the accommodation region and an open position for at least partly opening the accommodation region.

A bleed-back control valve is provided having a sidearm and an integrated three-way stopcock switching between two alternative fluid paths. One of the alternative fluid paths communicates with an inline pressure transducer embedded in the wall of the sidearm. The bleed-back control valve also includes a purge valve located near the blunted apex of a conical seal located in the main valve body. The purge may be opened to expel air from the space around the blunted apex.

A hemostatic valve, a sheath, and a catheter sheath assembly are provided. The hemostatic valve includes a valve body and a spool arranged in the valve body. The spool includes a spool main body and a cover body connected to a distal end of the spool main body. The spool main body defines an axial through hole therein. The cover body is operable to be opened or automatically closed relative to the spool main body to correspondingly deocclude or occlude the axial through hole. The hemostatic valve has an ideal sealing effect, can prevent blood leakage or air entering the human body, has high reliability, and is particularly suitable to be used with a dilator or other diagnostic and therapeutic device with a large diameter.

Needle assemblies and related methods in which a valve opener is used to push into a valve to open one or more slits on the valve to open the valve. The needle assemblies each includes a needle hub with a needle, a catheter tube with a catheter hub and the valve and valve opener positioned in the interior cavity of the catheter hub. The valve can have a valve skirt and a nose section of the valve opener can locate therein. One or more reliefs can be provided with the valve opener so that an elbow or diagonal section on a needle guard can project from a holding space within the valve opener through the relief.
