A needle tip shield may include a needle passageway that may receive a needle, a tip shield interior space that may receive a needle block, and a fluid restriction member. The fluid restriction member may be configured to restrict fluid leakage into and/or out of the needle tip shield. The fluid restriction member may be selected from the group consisting of: (1) a fluid impedance member located adjacent the needle passageway that may impede fluid from entering into the needle tip shield through the needle passageway; (2) a fluid retention member that may retain fluid within the tip shield interior space; and (3) an anti-splatter member that may inhibit fluid splatter when the needle block moves from an open position to a closed position within the tip shield interior space.

Inhibiting fluid leakage and splatter in catheter devices and systems

The present invention relates to a cap for a medical connector. More specifically, the present invention related to an antimicrobial cap for placement over a connector, wherein various features of the antimicrobial cap maintain the connector in an antiseptic state.

Antimicrobial caps for medical connectors

A catheter assembly is disclosed that includes a catheter adapter having a port disposed on its sidewall. A valve is coupled to the port to seal the opening in the port.

Catheter adapter port valve

A valve actuator that moves in a catheter assembly between a first position where a valve is closed and a second position where the valve is open, the valve actuator including a shaft portion at a distal end of the valve actuator that is configured to pierce the valve, a mating portion at a proximal end of the valve actuator that is configured to engage a Luer device, a diameter reduction region that connects the shaft portion and the mating portion, and a plurality of windows that extend through the valve actuator for flushing fluid, the plurality of windows being disposed in the diameter reduction region, wherein each of the plurality of windows does not extend a full length of the diameter reduction region.

Multi-use blood control safety catheter assembly

A medical instrument or device, such as a catheter, has echogenic properties, in addition to or as an alternative to radiopaque properties, to facilitate detection of the medical instrument or device during medical procedures using suitable imaging methods, such as ultrasound imaging and/or x-ray imaging methods. In example embodiments, an example catheter has a relatively increased radiopacity and echogenicity to facilitate a clinician with detecting the catheter with ultrasound imaging and/or x-ray imaging methods to assist the clinician with the insertion, placement, and/or maintenance of the catheter, for example.

Echogenic catheter and catheter system

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

A catheter assembly () comprising a catheter (), a needle () having a sharp distal tip (), and a catheter hub () connected to the catheter () having the needle () passing therethrough, the catheter hub () including a valve () having a preformed opening () that selectively permits or blocks a flow of fluid through the catheter (), a first inner diameter () that closes the valve (), and a second inner diameter () larger than the first inner diameter (), the second inner diameter () opening the valve (), wherein the valve () is in an open position upon axially compressing the valve () into engagement with the second inner diameter () of the catheter hub (), and the valve () is in a closed position upon releasing the valve () to engage the first inner diameter () of the catheter hub ().

Safety IV catheter with molded-open blood control valve

An intravenous delivery system may have a liquid source containing a liquid, tubing, and an anti-run-dry membrane positioned such that the liquid, flowing form the liquid source to the tubing, passes through the anti-run-dry membrane. The anti-run-dry membrane may be positioned within an exterior wall of a drip unit, and may have a weld surface secured to a seat of the exterior wall via application of compression to press the weld surface against the seat, and application of coherent light or vibration. In response to application of the coherent light or vibration, localized melting may occur, causing the weld surface to adhere to the seat. The anti-run-dry membrane may be modified to have a melting point close to that of the seat. Ultrasonic or laser welding may be applied in a manner that causes portions of the seat to melt and flow into pores of the weld surface.

IV membrane attachment systems and methods

The current invention relates to infusion devices, specifically to peripheral intravenous (IV) catheters. In particular, the invention relates to peripheral IV catheter assemblies having features to enable selective and reversible activation of fluid flow through the catheter assembly. Some implementations of the present invention include various configurations of septum valves having a barrier surface that is stressed to bias the barrier surface and provide a pathway through the septum valve.
