Aspects are directed to an improved suction catheter that increases the effectiveness of clearing the airway, reducing the need for separate suctioning and foreign body grasping instruments. The embodiments described herein provide medical personnel the ability to use one hand and catheter to selectively grasp an anatomically lodged foreign body while reducing the likelihood of lumen blockage and interruption of suction. The embodiments described herein further provide an auxiliary access port that allows insertion of a bougie instrument into a suction catheter. The suction catheter may be a Yankauer device or improved suction catheter with grasping housing. The bougie instrument may extend through the access port and a lumen of the catheter while still providing suction via the lumen. Due to the small size of the suction catheter, the bougie instrument may extend from the catheter's distal end when placed in close proximity to a patient's vocal cords.

Provided herein is a vascular access device including a catheter insertion apparatus and a needleless access connector unit. The catheter insertion apparatus includes a catheter assembly having a housing defining a passageway, a needle slidably mounted within the passageway and defining a needle lumen, a frame, and a catheter coupled to the frame, the frame sliding within the housing to advance the catheter within the needle lumen. The catheter insertion apparatus is operable between an initial configuration in which the needle extends distally from the housing and the catheter is retracted proximally within the needle lumen, and an actuated configuration in which the needle is retracted back into the passageway of the housing and the catheter extends distally from the housing. The needleless access connector unit is positioned at the proximal end of the catheter assembly frame and provides an access port to the catheter.

The present disclosure relates to a catheter assembly having an advancement feature for a shield needle. Catheter assembly vascular access devices using such assemblies are disclosed. The catheter assembly includes a catheter, an introducer needle, a needle hub, and a catheter distal tip support element. The assembly includes an advancement assembly disposed between the needle hub and the distal tip of the introducer needle, the advancement assembly configured to advance the catheter distal tip support element a distance sufficient to advance the distal end of the elongate tubular portion to cover the distal tip of the needle in the shielded position.
