Abstract:
1. A catheter adapted for use in passing fluids therethrough and into the arteries, veins, tissues, conduits, or organs of a patient, said catheter comprising: an elongate tubular body having a proximal end and a spaced distal end; a central lumen defined within said body and extending from the proximal end to the distal end thereof; means approximate the proximal end of said body for sensing a systemic fluid pressure therein the patient, comprising a sheath extended about an exterior periphery of said body and positioned approximate the proximal end of said body; means positioned at the distal end of said body for sensing the fluid pressure thereat; means for selectively adjusting the flow rate of fluid supplied to the central lumen based at least in part on the sensed systemic fluid pressure and the sensed fluid pressure at the distal end of the body; a first occlusive balloon disposed on the exterior of said body; and means for inflating said first occlusive balloon.
