    Abstract: An intravenous catheter system may include a catheter adapter, which may be integrated. The intravenous catheter system may also include a housing coupled to a proximal end of the catheter adapter, an introducer needle having a proximal end, a distal tip, and a needle lumen extending between the proximal end of the introducer needle and the distal tip, a guidewire disposed within the housing and the needle lumen, and a guidewire advancement element. The housing may include a proximal end, a distal end, and a slot. A proximal end of the introducer needle may be secured within the housing. The guidewire advancement element may extend through the slot and be moveable along the slot in a distal direction to move the guidewire from a retracted position to an advanced position, in which the guidewire may extend beyond the distal tip.

    Abstract: An IV catheter system (100) having a catheter component (102) and a needle component (104). The catheter component has a catheter hub (120), a cannula (126) extending distally from the catheter hub, and a push feature (190) extending outward from the catheter hub. The push feature has an outer surface (420) that receives contact from a digit to move the IV catheter system from an insertion configuration, in which the needle is within the cannula, to a fluid delivery configuration, in which the needle is outside the catheter hub. The needle component has a needle hub (150) and a needle (154) extending distally from the needle hub. The push feature is formed of a flexible material that causes the push feature, in response to pressure exerted on the outer surface by a dressing securing the catheter component to a patient, to deflect the outer surface toward the cannula axis.

    Abstract: Needle devices are disclosed in which a needle having a wall defining a needle lumen has a notch (120) formed through the wall. A transparent or semi-opaque window cover (130) made from a biocompatible material is provided over the notch. Blood flow through the needle lumen can be viewed through the notch with the window cover. The needle with the notch and window cover may be used with a variety of needle applications, including as catheter assemblies, indwelling assemblies, and most if not all over-the-needle type devices.

    Abstract: A low-profile universal passive protector is provided for an IV catheter comprising a hypodermic needle and a catheter. An elongate sheath defines a sheath cavity and a longitudinal axis. A slider is connected to the hypodermic needle and is movable along the sheath between first and second positions for withdrawing the needle into the sheath. A finger-press plate is coupled to the sheath and extends beyond the slider in a direction perpendicular to the longitudinal axis to define a plate height. A flashback body is coupled to the slider in a manner such that the flashback body and slider collectively define a cavity in fluid communication with the hypodermic needle. The flashback body is sized and configured to extend from the slider in a direction perpendicular to the longitudinal axis to define a flashback body height that is less than the plate height.
