Devices and methods for treatment of the Eustachian tube and sinus cavity

A polymeric stent for treating the Eustachian tube, the stent comprising:

• a tubular scaffold configured for implantation in the Eustachian tube, the tubular scaffold having a polymer substrate, the tubular scaffold including a proximal segment and a distal segment, the proximal segment including radially deformable rings, the radially deformable rings of the distal segment having a greater radial strength than the radially deformable rings of the proximal segment, wherein the tubular scaffold has an uncrimped configuration and a crimped configuration, wherein the scaffold is cut from a frustoconical tube so that in the uncrimped state a diameter of the rings decreases linearly from a distal end to a proximal end of the scaffold, wherein the proximal segment begins at an end ring at the proximal end of the tubular scaffold and the distal segment begins at an end ring at the distal end of the tubular scaffold, wherein the proximal segment abuts the distal segment.
