Claim:
1. An apparatus, comprising: a catheter shaft defining a first lumen and a second lumen; a proximal port in fluid communication with the first lumen, the proximal port having associated therewith a resilient valve member operable to seal around an infusion catheter extended through the proximal port; a first sensor, the first sensor operable to measure fluid pressure in the first lumen; a distal port in fluid communication with the first lumen, the distal port positionable within a vascular vessel of a patient and arranged to receive blood under pressure when positioned in the vascular vessel; an inflatable balloon mounted on the catheter shaft proximal of the distal port, the inflatable balloon having an inner void in fluid communication with the second lumen; the infusion catheter coaxially received within the first lumen, the infusion catheter having an infusion catheter shaft and a proximal port in fluid communication with an infusion lumen; a liquid input device in fluid communication with the proximal port of the infusion catheter; a second sensor, the second sensor associated with the infusion lumen and operable to measure pressure of fluid forced into the proximal port of the infusion catheter by the liquid input device; and a proximal inflation port in fluid communication with the second lumen; wherein the second sensor is disposed between the liquid input device and the infusion catheter; and wherein the liquid input device is removably coupled to the second sensor.
