Abstract:

An apparatus includes a feedback loop for controlling an extent of a gap (40) between a wall of a balloon (18) mounted on a catheter (12) and a wall (38) of a lumen (36) into which the catheter (12) is inserted. The apparatus includes a radiation detector (28) mounted within the balloon (18) for generating a feedback signal having information indicative of whether the extent of the gap (40) is greater than or less than a desired value. The feedback loop receives the feedback signal and controls a size of the balloon (18) to cause the extent of the gap (40) to approach the desired value.
