1. A vascular occlusion catheter for at least partial occlusion of a target vessel having an internal vessel wall, the vascular occlusion catheter comprising:
a proximal outer section;
a distal outer section;
a tip at a distal end of the catheter; and
an occlusion balloon connected to the proximal outer section and the distal outer section;
the proximal outer section having a first internal lumen and a second internal lumen, the first internal lumen being in fluid communication with the occlusion balloon;
the distal outer section having a distal internal lumen;
a hypotube having an internal hypotube lumen, the hypotube extending through the first internal lumen, through the occlusion balloon and into communication with the distal internal lumen, the hypotube operating as the primary load-bearing chassis of the vascular occlusion catheter;
a solid distal wire embedded in the distal outer section and extending toward the tip, the solid distal wire having a central axis that is radially offset from a central axis of the hypotube;
a first window formed in the proximal outer section;
a proximal sensor being positioned within the second internal lumen facing the first window;
a second window formed in the distal outer section;
a distal sensor being positioned within the distal internal lumen facing the second window; and
a display hub positioned along the proximal outer section, wherein the second internal lumen and the hypotube extend into the display hub, the display hub being electrically connected with the proximal sensor via the second internal lumen, and the display hub being electrically connected with the distal sensor via the internal hypotube lumen and the distal internal lumen.
