  • Publication number: 20230137347
    Abstract: A fluid transfer device including a catheter, an introducer adapted to attach the device to a peripheral intravenous line (PIV), an actuator movably coupled to the introducer, and a catheter support movably coupled to the introducer. The catheter support is positioned between the actuator and the distal end of the introducer. The actuator moves the catheter between a first position disposed within the introducer and a second position where the end of the catheter extends beyond the end of the introducer and into the PIV. The catheter support includes a rigid or collapsible tether and a hub attached to the tether and defining a passageway. The catheter extends from the actuator through the passageway of the catheter support to the distal end of the introducer. As the actuator moves the catheter, the actuator contacts the catheter support and moves the catheter support with respect to the introducer.

  • Publication number: 20230001157
    Abstract: A vascular access device may include a housing, which may include a distal end, a proximal end, and a slot. An advancement element may extend through the slot and may be configured to move linearly along the slot between a retracted position and an advanced position. In response to movement of the advancement element from the retracted position to the advanced position, a probe of the vascular access device may be advanced beyond the distal end. The vascular access device may include one or more features to reduce buckling of the probe and limit displacement of the probe. For example, the vascular access device may include a protrusion fixed within the housing distal to the advancement element. As another example, the vascular access device may include a distally-extending arm and/or a recess configured to receive the distally extending arm.
