Sinus stent

摘要

Apparatus and methods are described, including a method for treating a paranasal sinus of a subject. The method includes forming an artificial hole in a wall of the paranasal sinus, and, via the artificial hole, opening a natural ostium of the paranasal sinus. Other applications are also described.

1. Paranasal sinus apparatus comprising:
an implant, shaped to define a lumen, and securable in a wall of a paranasal sinus of a subject such that a first end of the lumen is in the paranasal sinus and a second end of the lumen is out of the sinus; a catheter, slidable through the lumen of the implant; a balloon, couplable to a distal portion of the catheter; and an expandable stent, slidable through the lumen of the implant while the implant remains secured in the wall of the paranasal sinus, shaped to define a lumen, and configured such that it may be expanded from a first shape to an expanded shape by an applied force, the balloon being inflatable via the catheter, and disposable within the lumen of the expandable stent such that inflation of the balloon expands the expandable stent, and the expandable stent being maintainable in the expanded shape when the balloon is deflated.
