Abstract: Needle devices having a component that provides the function of fixing a valve in a standard diameter sized catheter hub, the valve and/or the component provide or provides a proximally directed axial force for returning the valve opener from a distal position within the catheter hub to a proximal position within the catheter hub when a male Luer is disconnected from the catheter hub. Various components can be located inside a single hub body catheter hub that can restrict fluid flow, allow actuation to permit fluid flow, prevent needlestick injuries, and combinations thereof.

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 shaft section, proximal of the needle tip can be formed from a second material different from the first material. The needle tip is attached to the needle shaft to form the needle. 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: Needle assemblies and related methods having a needle hub with a needle, a catheter tube with a catheter hub and having the needle extending through the catheter tube, a valve positioned in an interior cavity of the catheter hub, a valve opener proximal of the valve, and a needle guard extending at least partially into the valve opener. The valve opener can be used with a range of needle sizes. The valve opener can be used for forming a sub-assembly while minimizing distortion or compression of a needle guard.

Abstract: Needle assemblies and related methods having a needle hub with a needle, a catheter tube with a catheter hub and having the needle extending through the catheter tube in a ready to use position. A valve is positioned in an interior cavity of the catheter hub, the valve having sections that can deflect in a distal direction and sections that can deflect in a proximal direction to open a fluid flow path through the valve. The valve can be deflected by a multi-piece valve opener.

Abstract: Catheters (104) with monitoring capabilities that can upload sensed or acquired data to a smart device (120) and/or a Cloud server (130). One or more sensors (106) can be located with a catheter assembly to collect data. The collected data can be processed by data analytics to analyze the data for usable information, such as to spot trends, patterns, and cause-effect relationships of the various detected conditions. The information can be viewed using an App or a web-browser dashboard or a local monitor.

Abstract: Needle devices are described. The needle devices can have a catheter hub, a needle hub, a housing located between the catheter hub and the needle hub. The housing can have an engagement mechanism to removably attach the housing to the catheter hub. The housing can further include a release element to release the engagement mechanism from the catheter hub to disengage the housing from the catheter hub. A flow regulator can be positioned inside the catheter hub. The flow regulator can include a stem and a sleeve.

Abstract: Safety needle assemblies that include a needle having a sharp distal tip and a needle tip cover mounted on the needle are disclosed. The needle tip cover includes a first portion having a channel receiving the needle and a second portion attached to the first portion. The second portion has a proximal wall, an opening in the proximal wall receiving the needle, a sidewall extending distally from the proximal wall, first and second spring arms extending transversely from opposite edges of the sidewall, and a third spring arm extending distally from the sidewall. The first spring arm and the second spring arm extend at least partially around the first portion. The third spring arm includes a flange extending radially inward and configured to bear against the needle to deflect the third spring arm radially outward against a spring restoring force in a ready to use position.

Abstract: A catheter assembly with a catheter, an outer casing positioned over the proximal end and at least part of the hub body of the catheter hub. The outer casing being pliable and has an interior cavity and a septum at a proximal end thereof. A needle hub removably coupled to a proximal end of the catheter hub with the outer casing wedged between the catheter hub and the needle hub. The needle hub has a proximal interior cavity and a shroud with a distal opening. A needle projects distally from the needle hub through the septum of the outer casing and has a needle tip extending out a distal opening of a catheter tube in a ready to use position.

Abstract: Safety needle assemblies, needle guards, and related methods are disclosed. The guards may be used on different needle applications to cover the tips of the needles. Exemplary needle guards are disclosed in which a curved bore profile is provided so that when the crimp or bulge on the needle retracts into the curved bore profile, the axial movement of the needle causes the needle guard to undergo a rotary movement.
