SinuSys Patency of Frontal Recess and Sphenoid Sinus Ostia Study

Overview

The goal of this study is to evaluate basic usability and confirm expected safety and effectiveness of SinuSys Dilation System when used to dilate frontal recess and sphenoid sinus ostia in patients with chronic rhinosinusitis.

Detailed Description

A multicenter, single arm, prospective study conducted to assess the safety and effectiveness of an osmotically-drive, low-pressure expansion device for dilation of frontal recess and sphenoid sinus ostia in patients with chronic rhinosinusitis (CRS).

Interventions

  • Device: Sinusys Dilation System
    • Dilation of frontal recess and/or sphenoid sinus ostia

Arms, Groups and Cohorts

  • Experimental: SinuSys Dilation System
    • Opening of previously constrained frontal recess and/or sphenoid sinus ostia via dilation procedure (sinuplasty)

Clinical Trial Outcome Measures

Primary Measures

  • Patency of treated target site
    • Time Frame: Patency immediately post device expansion and removal
    • Patency assessed by investigator via endoscopic evaluation of the target site

Secondary Measures

  • Patency of treated target site
    • Time Frame: 1 month and 3 months
    • Patency assessed by investigator via endoscopic evaluation of the target site
  • Reports of sinus related adverse events during the 3 months follow-up period
    • Time Frame: up to 3 months
