Abstract: A catheter arrangement and use of a catheter arrangement in infusion therapy. The catheter arrangement includes a catheter with a housing body, a hollow needle, a tube fitted onto a distal end of the housing body, a valve element arranged in the housing body with a fluid passage, and a fluid-conducting path extending through the housing body, the fluid passage and the tube. The needle extends longitudinally through the fluid-conducting path in a state of readiness of the catheter arrangement, and is drawn out of the fluid-conducting path in a state of use of the catheter arrangement. The valve element has an elastic wall portion through which the fluid passage extends. The fluid passage can be shifted by a fluid-pressure-induced elastic deformation of the wall portion between an open state, in which the fluid passage is open, and a closed state, in which the fluid passage is closed.

Abstract: 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.

Abstract: A needle assembly, such as a catheter assembly, having a needle shaft with a needle tip formed from a first rigid material for puncturing a subject.

The first material can have higher rigidity than the second material and the needle can project through a catheter tube and used in a catheter assembly.

Abstract: A needle assembly includes a catheter hub, a catheter tube extending distally from the catheter hub, and a needle hub having a needle having a needle tip extending out the catheter tube. A protective cap is positioned with the catheter hub and covers the catheter tube and the needle tip. The protective cap has a casing having a casing body, a first opening at a proximal end of the casing body, a proximal cavity having the needle tip and the catheter tube located in the proximal cavity, a second opening at an end opposite the first opening and opening into a distal cavity, and a rim at the second opening. A lid is removably attached to the rim at the second opening to seal a solution inside the distal cavity. The solution is dispensable from the distal cavity following separation of the lid from the rim.

Abstract: A sensing system for sensing a potential complication at a venous catheter site. The system includes a sensor module for attachment at the site of the catheter. The sensor module includes a pressure sensor configured to generate pressure data representing measured pressure at the site of the catheter; a temperature sensor configured to generate temperature data representing measured temperature at the site of the catheter; and two pairs of bio impedance electrodes that generate bioelectrical signals representing bioelectrical activity at the site of venous catheter and a transmitter for transmitting the pressure, temperature data and bio impedance data.

Abstract: Peripheral intravenous catheter assemblies with capabilities for both blood sampling and catheterization can have a blood collection holder with a needle hub attached to a catheter hub. The combination catheter assembly and blood sampling holder can be called a catheter and holder assembly. Blood sampling can be done directly through the needle and the blood collection holder after cannulation. After blood sampling, the blood collection holder and the needle can be removed, leaving the catheter hub with the patient for IV infusion. The catheter hub can be a straight catheter hub or can include a side fluid port for use in as an integrated IVC.

Abstract: Needle assemblies and related methods are disclosed. The needle assemblies can include a catheter hub and a catheter tube and wherein the catheter hub has a low profile to facilitate attaching the catheter hub to the skins of a patient.

Abstract: A needle device, such as a catheter assembly, includes a catheter tube attached to a catheter hub, a needle attached to a needle hub, and an optional needle guard for covering the needle tip in a protective position. Different markets can utilize the same needle device by separately forming an extension clip having a gripping member or gripping pad for attaching to the needle device for those markets that require the gripping member or pad.

Abstract: Aspects of the present disclosure include needle devices in which a needle has a notch or slot. A flashback indicator is provided at least in part in the needle lumen at the notch, adjacent the notch, or partially inside and partially outside of the notch. In use, blood flow through the needle lumen is indicated at the flashback indicator. When used with a catheter tube, the flashback indicator can be viewed through the catheter tube. The needle with the notch and flashback indicator may be used with a variety of needle applications, including as catheter assemblies, indwelling assemblies, and most, if not all, over-the-needle type devices.

A blood collection device is attached directly or indirectly to the needle hub of the needle assembly and/or to a catheter hub, such as through a Y-site or adaptor connected to a tubing that is connected to the catheter hub. The needle is configured to access the vascular system to draw blood, which then passes to the blood collection device via the needle lumen, which has a tip having a discontinuity opening, an opening with a movable stem, or a shaft element with a lumen.
