ESS, endoscopic sinus surgery.

Breakthrough technology that opens the sinus cavity and delivers mometasone furoate1-3

  • PROPEL implants feature an innovative 2-in-1 mechanism that opens the sinuses while delivering mometasone furoate, an advanced corticosteroid, directly where it is needed
  • Mometasone furoate was selected for use in PROPEL implants for its optimal sinonasal drug characteristics: highly lipophilic, targeted and potent, and low systemic bioavailability
  • PROPEL implants are composed of a bioabsorbable polymer that breaks down between 30-45 days so implant removal is not required
  • PROPEL has a non-obstructive self-expanding design that allows for mucociliary clearance and the delivery of topical rinses

Delivers the power of robust, clinically proven benefits1-3
