摘要：
Catheter systems configured for emergency blood-vessel occlusion and associated devices, systems, and methods are disclosed herein. A catheter system configured in accordance with a particular embodiment includes a catheter, a sheath, and an extracorporeal proximity sensor. The catheter includes an elongated body having a tip, a sealing portion, and a main shaft proximal to the sealing portion. The tip is configured to dilate a blood vessel ahead of the distal end portion of the sheath as the catheter and the sheath are advanced together through the blood vessel. The distal end portion of the sheath is configured to fit snugly around the sealing portion. The catheter further includes a balloon and a proximity-sensor target less than about 10 centimeters from the balloon. The proximity sensor is configured to receive a signal from the proximity-sensor target to aid in positioning the balloon without fluoroscopic guidance.
