Gore Bio-A Fistula Plug
FDA Clearance Information
The Gore Bio-A Fistula Plug was cleared via the FDA 510(k) pathway on March 27, 2009. It is manufactured by W.L. Gore & Associates and classified as a Class 2 device.
What It Is
FDA-Cleared Indications
- Treatment of complex anal fistulas
- Treatment of rectovaginal fistulas
Clinical Applications
- Sphincter-sparing repair of selected complex anal fistulas
- Occlusion of an anal fistula tract after appropriate drainage and preparation
- Sphincter-sparing treatment of selected rectovaginal fistulas
- Use as a bioabsorbable scaffold for tissue regeneration across a fistula tract
Reported off-label uses
- Treatment of refractory fistulas associated with Crohn disease has been reported in clinical practice, but use should be considered off label when it falls outside the device labeling.
Off-label use: these uses are reported in practice or the literature but are not part of the FDA-cleared indications. Physicians may use a cleared device off-label based on their medical judgment; the manufacturer may not promote off-label uses.

Practical Considerations
- The plug must be selected and trimmed to fit the length and diameter of the prepared fistula tract; available sizes depend on the specific product configuration.
- The device is intended for placement by a qualified clinician after the fistula tract has been identified, drained and prepared according to the surgical technique.
- It is bioabsorbable and is not intended to remain permanently as an implant; the timing of absorption and tissue remodeling can vary.
- MRI safety should be confirmed in the current manufacturer’s instructions for use. A device-specific MRI designation should not be assumed from the fact that the material is bioabsorbable.
- Active uncontrolled infection, undrained abscess, unsuitable tract anatomy or inability to adequately prepare the tract may make placement inappropriate. Patient selection and management of the underlying disease remain important.
