Patent number: 11957850Abstract: Needle assemblies and related methods in which a valve opener is used to push into a valve to open one or more slits on the valve to open the valve. The needle assemblies each includes a needle hub with a needle, a catheter tube with a catheter hub and the valve and valve opener positioned in the interior cavity of the catheter hub. The valve can have a valve skirt and a nose section of the valve opener can locate therein. One or more reliefs can be provided with the valve opener so that an elbow or diagonal section on a needle guard can project from a holding space within the valve opener through the relief.Type: GrantFiled: January 28, 2021Date of Patent: April 16, 2024Assignee: B. Braun Melsungen AGInventors: Kevin Woehr, Jarryd Keng Gene Ng, Boon Ping Neoh

Patent number: 11684757Abstract: 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: GrantFiled: August 18, 2017Date of Patent: June 27, 2023Assignee: B. Braun Melsungen AGInventors: Hang Khiang Chng, Wen Jenn Lim, Khai Tick Sim, Yueh Shiuan Ghoo, Hui Kuun Teoh, Meng Mun Chong, Zi Lai Lim, Boon Ping Neoh, Jarryd Keng Gene Ng

Publication number: 20210308427Abstract: 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.Type: ApplicationFiled: June 15, 2021Publication date: October 7, 2021Applicant: B.
