1-73. (canceled)
Paranasal sinus apparatus comprising:
- an implant, implantable in a wall of a paranasal sinus of a subject, and shaped to define a lumen;
- 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, 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.
78-105. (canceled)
The method according to claim 112, wherein inserting the medical instrument into the paranasal sinus comprises inserting a stent into the paranasal sinus via the artificial hole in the wall of the sinus, and wherein using the medical instrument to open the natural ostium of the sinus comprises:
- placing the stent in the ostium from inside of the sinus;
- and
- securing the stent in the ostium by expanding the stent.
109-110. (canceled)
A method for treating a paranasal sinus of a subject, the method comprising:
- forming an artificial hole in a wall of the paranasal sinus;
- and
- via the artificial hole, opening a natural ostium of the paranasal sinus.
