Occlusion catheter system for partial occlusion or full occlusion
A vascular occlusion catheter for at least partial occlusion of a target vessel includes proximal and distal shafts, with an occlusion balloon connected therebetween. The proximal shaft has a proximal internal lumen, in fluid communication with the occlusion balloon. The distal shaft has a distal internal lumen. A hypotube having an internal lumen extends through the proximal lumen and the occlusion balloon and into communication with the distal lumen. The catheter includes at least one of (i) a distal sensor positioned within the distal lumen and facing an opening formed in the distal shaft, or (ii) the proximal shaft further includes a sensor lumen, and a proximal sensor is positioned within the sensor lumen and facing an opening formed in the proximal shaft. A display hub is mounted to the proximal shaft, and is electrically connected with the at least one of the distal sensor or the proximal sensor.
