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 and a tail formation 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 and a tail formation 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 ; <EOS>
