1. A catheter apparatus for controlling hemorrhage in an enclosed surgical arena, said apparatus comprisinga flexible catheter body configured for travel within a blood vessel extending to the surgical arena by percutaneous insertion or cutdown to access a site in the vessel, said catheter body including an elongated tubular wall having proximal and distal ends, and having at least an inflation lumen and an optical fiber extending between said ends, said fiber being configured for coupling to receive light at the proximal end and guide light to the distal end, and said fiber being configured at said distal end as a beacon which emits said received light through the wall of the vessel as a precise position marker visible externally of the vessel wall for allowing positioning of said catheter distal end in the vessel, anda balloon secured at said distal end of the flexible catheter body and inflatable via said inflation lumen, said balloon being configured for travel with said flexible catheter along the blood vessel, said inflation lumen having a distal opening into said inflatable balloon for providing a fluid flow for rapid inflation and deflation of the balloon, whereby, when precise position of the balloon within a blood vessel is visually confirmed by viewing said beacon, the balloon is disposed for inflation to occlude blood flow and prevent hemorrhage in an identified region of the surgical arena, andmagnetic material secured to said balloon for magnetic engagement and positioning of the balloon by manipulation of a magnet located outside the blood vessel.
