Prepackaged collections of devices and supplies designed to deliver stents intended to enlarge the lumen of the passages to a paranasal sinus (i.e., frontal, ethmoid, or sphenoid). These kits typically include an instrument consisting of a mechanism to deploy the stent at the proximal end and a hydrophilic sheath that permit sinus access at the distal tip. The implantable endoprosthesis (i.e., the stent) is mounted on the distal tip and fixed to the sinus mucosa. Other products (e.g., saline, alcohol, anesthetics) may be also included in the kits for use during the stenting procedure. Paranasal stent delivery kits are intended to deploy stents used for ventilation and drainage of fluids from the sinus; they are mainly used after functional endoscopic sinus surgery (FESS).
