The sinus balloon 104 is designed to be non-compliant or semi-compliant.{123} The diameter of the non-compliant balloon does not vary significantly with inflation pressure and that of the semi-compliant balloon will vary only to the extent that it will “hourglass” or “dog-bone” about a target region.{124} The balloon itself may be any shape such as round, triangular, oval or square.{125} In the embodiment shown in FIG. 1, the balloon is round and semi-compliant.{126} A stiffening member (in this case a hypotube 116) is incorporated on the proximal end of the medical device (at the distal end of the proximal shaft portion 122) to provide rigidity during insertion through a sinus guide catheter, as further described below.{
