  • Patent number: 10357636
    Abstract: An IV access device can include a needle hub having an angled paddle grip to facilitate insertion of the catheter at a low angle. The angled paddle grip can also minimize any interference that an extension tube or stabilization platform may cause during insertion. By employing an angled paddle grip, the catheter can be inserted while maintaining the stabilization platform in an orientation that is substantially parallel to the patient's skin. Also, in cases where the extension tube may run parallel with the stabilization platform, the angled paddle grip can prevent the extension tube from extending into the patient's skin during insertion. This will prevent the stabilization platform and/or the extension tube from catching on the patient's skin or otherwise inhibiting a smooth insertion of the catheter.

  • Publication number: 20190209809
    Abstract: A medical instrument or device, such as a catheter, has echogenic properties, in addition to or as an alternative to radiopaque properties, to facilitate detection of the medical instrument or device during medical procedures using suitable imaging methods, such as ultrasound imaging and/or x-ray imaging methods. In example embodiments, an example catheter has a relatively increased radiopacity and echogenicity to facilitate a clinician with detecting the catheter with ultrasound imaging and/or x-ray imaging methods to assist the clinician with the insertion, placement, and/or maintenance of the catheter, for example.

  • Patent number: 10342918
    Abstract: An infusion system having an integrated inserter and infusion set (10) for containing and placing a flexible catheter (40), and a retractable introducer needle (26), wherein the catheter (40) is isolated from movement after placement. The integrated inserter and infusion set (10) includes a hub (20), having a user push button (30) to activate the device for catheter (40) placement. An adhesive liner (34) can be provided to cover an adhesive layer (36), such as pressure sensitive adhesive (PSA), on the bottom of the device (10).

  • Publication number: 20190167896
    Abstract: 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. The barrel includes an aperture that receives the actuator button for locking the spring in a compressed condition. Depression of the actuator button enables the spring to propel the needle assembly into its proximal position. A safety mechanism prevents inadvertent depression of the actuator button.

  • Publication number: 20190167966
    Abstract: A catheter assembly may include a catheter adapter, a septum housing, and a septum. The catheter adapter may include a distal end, a proximal end, an inner wall extending between the distal end and the proximal end, and a lumen formed by the inner wall. The septum housing may include one or more protrusions and may be secured to the inner wall by one or more of the following: an interference fit between the one or more protrusions and the inner wall, a snap fit between the one or more protrusions and the inner wall, and bonding between the one or more protrusions and the inner wall. The septum may be at least partially disposed within the septum housing and configured to at least substantially seal the lumen.

  • Patent number: 10220137
    Abstract: An infusion set preferably for use with an inserter is disclosed. The infusion set includes a septum cap that encapsulates an upper resilient septum and a lower resilient septum of a base, and includes at least one radial port to receive insertion of a blunt cannula when an extension set hub is engaged with the infusion set in a direction substantially parallel to the skin surface. The extension set hub is configured to provide a snap-fit engagement with the septum cap, wherein the blunt cannula of the extension set hub is guided through the radial port of the septum cap and penetrates the interface between the upper septum and the lower septum. The extension set hub and the septum cap can be rotated in a 360 degree manner about the base of the infusion set.
