  • Patent number: 11684757
    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.
    Type: Grant

  • Patent number: 11103681
    Abstract: Needle assemblies are disclosed having a multi-purpose protective cap. The needle assemblies can embody a catheter assembly having a catheter hub and a catheter tube or a hypodermic needle mounted on a needle hub. The multi-purpose cap includes a first section covering the needle and a second section having a base portion for covering a hub, such as a needle hub or a catheter hub. The first section and the second section are separable from one another along a detachment line and the second section is re-useable as a securement device.

  • Patent number: 10702670
    Abstract: A medical device packaging assembly includes a cover (10), a medical packaging paper (20), a medical device (50), and an adhesive dressing (30). The cover has a pocket (14) and a perimeter (12) extending from the perimeter of the pocket. The medical packaging paper forms a hermetically tight seal between the medical packaging paper and the perimeter of the cover around the pocket. The medical device is contained in the hermetically sealed pocket along with the adhesive dressing. The adhesive dressing is removably adhered to the medical packaging paper.

  • Patent number: 10449331
    Abstract: Needle devices are described. The needle devices can have a catheter hub, a needle hub, and a valve system for controlling fluid flow through the catheter hub. The valve system can include a valve and a valve retainer. The valve can have flow holes for fluid flow therethrough or can have a valve piece for controlling flow through flow holes located externally of the valve. A needle guard is usable with the needle device to block a tip of the needle. A valve opener can also be used to open the valve.

  • Patent number: 10173002
    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.

  • Patent number: 9737252
    Abstract: The present disclosure is directed to a needle assembly for drawing blood. The needle assembly can be a standalone or part of an over-the-needle medical device, such as an intravenous catheter. 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.
