A catheter assembly includes a flexible catheter (22), a needle (12) having a sharp distal tip, the needle (12) disposed in the flexible catheter (22) and moving from a first position that exposes the needle (12) to a second position, an outer member (26) that is configured to engage and disengage a catheter hub (14), an inner member (28) disposed in the outer member (26), and a needle protection (30) member disposed in the inner member (28), the needle protection member (30) enclosing at least a portion of the needle (12) when the needle (12) is in the second position.

A hemostasis valve assembly for use in a medical device. The hemostasis valve assembly may include a main body portion defining an internal cavity, a seal cartridge disposed within the internal cavity, and a low pressure valve assembly positioned within the internal cavity adjacent to the seal cartridge. The low pressure valve assembly may include a first valve member having a first valve body and a second valve member having second valve body. A portion of a distal side of the first valve member may abut at least a portion of a proximal side of the second valve member.

A catheter assembly (10) comprises a catheter (22), a needle (12) having a sharp distal tip disposed in the catheter (22), a catheter hub (14) housing the catheter (22) and the needle (12), the catheter hub (14) having a collar (34) including a notch (36), a needle shield (20) connected to the catheter hub (14) when the needle (12) is in a first position, and a clip (40) disposed in the needle shield (20) that cooperates with the needle (12), wherein the clip (40) engages the catheter hub (14) in the first position of the needle (12), and the clip (40) disengages the catheter hub (14) via the notch (36) when the needle (12) is retracted to a second position to enclose at least a portion of the needle (12). The clip (40) is mounted in the outer housing (38) of the needle shield (20) via a spade (66) having an outer wall (70) exposed to the outside of the needle shield (20), in order to reduce the overall width of the needle shield (20).

The present invention relates to a multiple-use intravenous (IV) catheter assembly septum and septum actuator. In particular, the present invention relates to an IV catheter assembly having a stationary septum actuator and a blood control septum, wherein the blood control septum is configured to slide within a catheter adapter of the IV catheter assembly between a compressed state and an uncompressed state. When in the compressed state, a slit of the blood control septum is opened and the septum comprises stored compressive potential energy. When the septum is released from the compressed state, the stored compressive potential energy is release and the blood control septum is restored to its original shape, thereby closing the septum's slit.

The present disclosure relates generally to the field of medical devices. In particular, the present disclosure relates to valve configurations providing sealable access for medical instruments to a working channel, such as a working channel for an endoscope.

An indwelling needle having: inner needle that punctures living body; outer needle inserted into living body with inner needle as inner needle penetrates outer needle and punctures living body; main body disposed along axis of inner needle; branch part that branches from main body. Indwelling needle includes: outer needle hub has passage in communication with interior of outer needle; elastic member disposed within outer needle hub, penetrated by inner needle, and flexible solid part that blocks fluid flow to proximal end side of main body when inner body is removed; holder attached to proximal end of elastic member. Elastic member forms at least part of passage that allows communication between interior of outer needle and branch part, has end surface inclined relative to axial direction. Outer needle hub has guide part engaged with elastic member or holder and guides rotation direction of elastic member around axis to certain direction.

The present invention relates to methods, devices and systems for performing the removal of thrombus from a vessel lumen. More particularly the present invention relates to a thrombectomy system that includes an elongate catheter and a disposable aspiration pump and methods of performing medical procedures to remove clots, thrombus and emboli to re-establish the normal intravascular flow of blood.

A catheter assembly comprises a catheter (18), a needle (12) having a sharp distal tip disposed within the catheter (18), a catheter hub (14) connected to the catheter (18) having the needle (12) passing therethrough, the catheter hub (14) including a valve (38) that selectively permits or blocks a flow of fluid through the catheter (18), a valve actuator (54) that moves between a first position and a second position, and a return member (56) that returns the valve actuator (54) from the second position to the first position, and a needle protection member (176) that encloses the sharp distal tip of the needle (12).

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 medical valve can include a housing that includes a sidewall and defines a chamber. The medical valve can include a septum coupled to the housing. The septum can include a proximal surface and a selectively openable closure positioned within the chamber. The medical valve can further include a plurality of projections that extend away from the sidewall and are configured to contact the proximal surface of the septum to oppose movement of a restricted portion of the septum in a proximal direction such that an aspiration cracking pressure required to open the closure to permit fluid flow through the septum in the proximal direction exceeds an infusion cracking pressure required to open the closure to permit fluid flow through the septum in the distal direction.
