An airway dilation device comprising: • a catheter, being dimensioned and configured for insertion at least partially into an airway, the catheter having an inflating end, and a distal end; • a continuous inflation tube, being housed substantially concentrically within the catheter, the inflation tube having a lumen defined by its inner wall, and terminating in the same inflating end as the catheter; • a duct, for the insufflation of a fluid, the duct also being housed substantially concentrically within the catheter, and bounded by the inflation tube along at least some of the length thereof, the duct being sealed hermetically against any fluid flow communication between it and the inflation tube; • a cluster of balloons, arranged in a substantially circular arrangement about the wall of the catheter, the balloons being manipulated selectively between a stowed condition, in which the balloons are deflated, and a deployed condition, in which the balloons are inflated, and wherein each balloon further includes a cone formation (140, 170) and a tail formation (130, 150) on each end of each respective balloon, being the proximal end and the distal end; • a film layer for providing additional support to the cluster of balloons, wherein the film layer follows, at least partially, the contours of at least some of the balloons in the cluster, and is bonded to the inward-facing surface of the balloons; and • inflating means, for inflating the balloons; wherein, first, when in the stowed condition, each balloon is folded and staggered relative to each adjacent balloon, to prevent a substantial overlay between each pair of adjacent balloons, so as to achieve an optimal, smallest diameter of the complete cluster of balloons and wherein, second, continuous insufflation remains possible, even when the balloons are in their deployed condition. • a catheter, being dimensioned and configured for insertion at least partially into an airway, the catheter having an inflating end, and a distal end; • a continuous inflation tube, being housed substantially concentrically within the catheter, the inflation tube having a lumen defined by its inner wall, and terminating in the same inflating end as the catheter; • a duct, for the insufflation of a fluid, the duct also being housed substantially concentrically within the catheter, and bounded by the inflation tube along at least some of the length thereof, the duct being sealed hermetically against any fluid flow communication between it and the inflation tube; • a cluster of balloons, arranged in a substantially circular arrangement about the wall of the catheter, the balloons being manipulated selectively between a stowed condition, in which the balloons are deflated, and a deployed condition, in which the balloons are inflated, and wherein each balloon further includes a cone formation (140, 170) and a tail formation (130, 150) on each end of each respective balloon, being the proximal end and the distal end; • a film layer for providing additional support to the cluster of balloons, wherein the film layer follows, at least partially, the contours of at least some of the balloons in the cluster, and is bonded to the inward-facing surface of the balloons; and • inflating means, for inflating the balloons;
