Publication number: 20250025669Abstract: A catheter assembly may include a catheter, catheter adapter, needle, needle guard, and housing. The housing may be coupled to the needle guard and disposed within a lumen of the catheter adapter. The needle guard may include first and second resilient arms, which may include first and second curved portions, respectively. When the needle is in a ready position, the first and second curved portions may be urged by a shaft of the needle into retaining contact with an inner wall of the catheter adapter. When the needle is in the retracted position, the shaft may no longer bias the first and second resilient arms outwardly such that the retaining contact between the first and second curved portions and the catheter adapter is released, and the housing and the needle guard enclose a distal tip of the needle.Type: ApplicationFiled: October 2, 2024Publication date: January 23, 2025Inventors: S.

Patent number: 12194249Abstract: The present invention relates to a multiple-use intravenous (IV) catheter assembly septum and septum actuator. In particular, the present invention relates to an IV catheter assembly having a stationary septum actuator and a blood control septum, wherein the blood control septum is configured to slide within a catheter adapter of the IV catheter assembly between a compressed state and an uncompressed state. When in the compressed state, a slit of the blood control septum is opened and the septum comprises stored compressive potential energy. When the septum is released from the compressed state, the stored compressive potential energy is release and the blood control septum is restored to its original shape, thereby closing the septum's slit.Type: GrantFiled: September 21, 2022Date of Patent: January 14, 2025Assignee: Becton, Dickinson and CompanyInventors: Darin Charles Vincent, S.

Publication number: 20250000405Abstract: Ported catheters can be configured to facilitate insertion of a blood draw device or other vascular probe or instrument. A ported catheter may include a bushing, or wedge, that is shaped to provide a smooth entry and advancement of a tube of a blood draw device that is coupled to the ported catheter, whether via a proximal opening or a port of the ported catheter. Such a bushing may be particularly beneficial when the port of the ported catheter is oriented at an angle towards the catheter. By incorporating such a bushing, a ported catheter may be better able to minimize the occurrence of kinking or bending of the tube of the blood draw device. A ported catheter may also include a catheter strain relief feature to minimize the occurrence of kinking or bending of the tube of the blood draw device while it is extended through the catheter.Type: ApplicationFiled: June 28, 2023Publication date: January 2, 2025Inventors: Prasad Govindaraj, Meenakshi Sankar Gomathinayagam, Sridhaar Nandakumar, Jonathan Karl Burkholz, Weston F.

Patent number: 11998719Abstract: A sealed fluid transfer device comprised of tubing, a proximal fitting, and a distal needle assembly is provided. The needle assembly includes a needle hub secured to a needle cannula. A cantilevered actuator arm extends outwardly from the needle hub having an actuator button at its free end. The needle assembly is disposed in a barrel and can move from a distal position, where the needle is exposed, to a proximal position, where the needle is shielded. The barrel includes a septum which seals the barrel. A spring is disposed in the barrel for propelling the needle assembly to the proximal position.
