  • Publication number: 20230093088
    Abstract: An extravascular system is provided which includes a catheter adapter having a blood control septum configured to control flow of a fluid through the catheter adapter, the catheter adapter further having a catheter configured for intravenous insertion. The extravascular system further includes a septum activator slidably inserted within the catheter adapter and configured for advancement through the blood control septum to provide a fluid pathway through the blood control septum. Further still, the extravascular system includes an external safety mechanism comprising a needle hub and a needle shield interconnected via a tether, wherein the needle shield includes a safety clip that is configured to retain a sharpened end of the introducer needle within the needle shield. Some implementations further comprise an access port forming a portion of the catheter adapter and providing selective access to the lumen of the catheter adapter.

  • Patent number: 11571551
    Abstract: An IV catheter system may have a catheter component with a catheter hub, a cannula extending distally from the catheter hub, and a push feature adjacent to the catheter hub. The IV catheter system may also have a needle component with a needle hub, a needle extending distally from the needle hub along an axis, and a grip extending from the needle hub, generally parallel to the axis, with a pull feature. In the insertion configuration, the needle may be positioned within the cannula and the distal end of the needle hub may be seated in a needle port of the catheter hub. In the fluid delivery configuration, the needle may be positioned outside the catheter hub. The push and pull features may be positioned to facilitate manipulation with a single hand to move the IV catheter system from an insertion configuration to a fluid delivery configuration.

  • Publication number: 20220080159
    Abstract: A catheter system may include a catheter hub, a septum disposed within the catheter hub, a catheter tube extending from the catheter hub, a needle hub, and an introducer needle secured within the needle hub. The catheter hub may include a push tab and one or more ribs, which may extend outwardly from an upper surface of the catheter hub. The ribs may be shorter in height than the push tab and/or may be generally parallel to the push tab. The introducer needle may include a flashback notch. In response to insertion of the introducer needle into vasculature, blood may flow into the introducer needle, through the flashback notch, and into a flashback chamber disposed between the septum and the catheter tube. The flashback chamber may be disposed distal to the push tab and the ribs, which may improve visualization of the flashback chamber by a user.

  • Patent number: 9789289
    Abstract: An integrated individual package and an introducer needle or wire for placing a catheter in a patient's vasculature, wherein the package doubles as a grip for placing the catheter. Prior to activation, the catheter is coaxially and slidably disposed over the introducer needle and the catheter and introducer needle assemblies are contained within the integrated package grip. The device is activated as the catheter and introducer needle assemblies are simultaneously transitioned from a closed position to an open position wherein the catheter and introducer needle assemblies are oriented for insertion into a patient's vasculature. Following placement of the catheter in a patient's vasculature, the device is deactivated as the introducer needle is withdrawn and transitioned from the open position to resume the closed position. The package grip comprises a sharps shuttle to protect a clinician from needle stick injuries.

  • Patent number: 9775972
    Abstract: The present invention extends to a design of a needle hub and an actuator of a catheter assembly that allows the needle hub and actuator to interlock within the catheter hub. This interlocking allows the needle hub to be inserted into the catheter hub thereby increasing the rigidity of the catheter assembly. The interlocking can be accomplished by forming channels in the proximal end of the actuator and corresponding protrusions from the distal end of the needle hub. In some embodiments, the channels and protrusions can be formed at the top and bottom of the catheter hub and needle hub respectively to thereby increase the vertical rigidity of the catheter assembly. The increase in vertical rigidity can prevent flexing of the catheter hub with respect to the needle shield when a downward force is applied to the catheter assembly such as is common during insertion of the needle.
