Abstract: A system can include a handle and a needle fixedly secured to the handle. The needle can include a distal tip that can be inserted through a sidewall of a vessel of a patient. The system can further include a catheter that defines a lumen through which the needle extends and includes an engagement surface at an interior thereof. A cannular stiffener can be positioned within the lumen of the catheter at an exterior of the needle and can include an engagement surface that can press distally on the engagement surface of the catheter to advance the catheter distally over the needle and through a lumen of the vessel when the stiffener is advanced distally over the needle. The system can further include a stiffener hub attached to the stiffener, the stiffener hub being movably coupled with the handle so as to translate relative thereto.

Abstract: A system for intraosseous access can include an elongated instrument that is positioned within a cannula portion of a cannula assembly. The system can include a shield that is coupled with both the elongated instrument and the cannula assembly when in an unlocked state. The shield can permit proximal movement of the elongated instrument relative thereto when in the unlocked state. The shield can automatically transition to a locked state to attach to a distal end of the elongated instrument to restrict access to a distal tip of the elongated instrument.

Abstract: An intraosseous access system can include a hub coupled to a cannula that can be introduced into a bone of a patient. The system further includes a securement device that can couple with the hub when transitioned from an open orientation to a closed orientation. The securement device includes a first segment and a second segment that are spaced apart from each other when the securement device is in the open orientation and are approximated and secured to each other when the securement device is in the closed orientation. The first segment includes a first receptacle that receives a portion of the hub therein and contacts the hub to restrain movement of the hub relative to the securement device when the securement device is coupled with the hub in the closed orientation. The first segment also includes a first arm coupled to the first receptacle, the first arm biasing the first receptacle toward the hub when the securement device is coupled with the hub in the closed orientation.

Abstract: An intraosseous access system can include a needle that defines a lumen and a longitudinal axis about which the needle can be rotated during an insertion event. The needle can include a proximal end that remains at an exterior of a patient during use, a distal end that can be inserted through the skin of the patient into contact with a bone of the patient, and a distal tip at a distalmost point of the distal end of the needle that is positioned at the longitudinal axis of the needle. The system can further include an obturator sized to be received within the lumen of the needle that can inhibit material from entering the needle as the system is inserted into the bone.
