A handheld vascular access device for gaining access to a patient's vessel includes a hub, a plurality of access needles and a manifold. The hub has an inner wall and side walls that define a plurality of ports. Each of the plurality of ports has a proximal port end and a distal port end. The proximal port ends define a proximal cross-sectional area and the distal port ends define a distal cross-sectional area. The proximal cross-sectional areas are greater than the distal cross-sectional areas. Each of the plurality of ports taper from the proximal port end to the distal port end. The plurality of hollow access needles is arranged along a plane and fixedly coupled to the distal end of the hub. Each of the plurality of needles has a tip. The manifold removably engages the hub at the proximal end of the hub.

A system for deploying and selectively inflating a thoracic aortic balloon at a desired location within the thoracic aorta for resuscitative aortic occlusion, inferior to the left subclavian artery, without the aid of fluoroscopy is described. Using CT imaging data, a distance between readily identifiable and consistently located external landmarks of torso extent is measured. Next, using the same data, a second distance from the femoral artery to a desired aortic occlusion location inferior to the left subclavian artery is determined. A correlation between the external measure of torso extent and the desired intra-arterial (i.e. endovascular) distance within the torso is made. Using a nomogram, a calibrated endovascular resuscitative thoracic aortic occlusion system can be positioned to this desired location on any injured individual with end-stage shock and impending cardiovascular collapse or death without the aid of fluoroscopy for delivery or balloon inflation.

A vascular access system and method of use for said system. The vascular access system generally comprises a body member; a shuttle member movably coupled to the body member; and a plurality of access needles fixedly coupled to the shuttle member and extending from the body member to penetrate a patient's skin.
