Abstract: Disclosed is an intravascular device for an aspiration procedure that provides desirable pushability, torque-ability, flexibility, and hoop strength characteristics. The intravascular device incorporates a stacked configuration of microfabricated cut patterns that improve the navigability of the intravascular device during vasculature procedures. The intravascular device may also include a channel configured to hold a radiopaque marker to aid in navigation and location of the intravascular device during a procedure.

Abstract: Embodiments disclosed herein are generally directed to blood flash detection systems and methods thereof. Embodiments include an indicator device including a needle and needle hub, defining a lumen and in fluid communication with a medical line. The needle hub includes a marker, such as an RFID tag, with electrodes extending to the lumen. When a fluid flow, for example blood, enters the lumen, an electrical connection between the electrodes is bridged, completing the circuit and activating the marker. The marker can then be responsive to an interrogation signal, and can provide a response signal. The response signal can be detected and interpreted by a detection device that indicates to a user that the vasculature has been accessed without the user directly observing the insertion site or the device.
