Further study details as provided by Miguel L. Tedde, University of Sao Paulo:

Primary Outcome Measures:
  • Closure of tracheoesophageal fistulas with the Gore Helex Septal Occluder [ Time Frame: 6 months ]

    The closure will be confirmed by endoscopic or bronchoscopic observation of the fistula at regular intervals: one week, two weeks, and four weeks after implant of the occluder.

    A thorax CT scan will ascertain correct positioning and stability of the occluder.

Enrollment: 4
Study Start Date: June 2010
Study Completion Date: December 2012
Primary Completion Date: July 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Fistula closure with occluder
Patients with benign tracheoesophageal fistulas will be submitted to the correction with the occluder.
