Clinical experience across multiple hernia repair procedures
Complex ventral hernia repair with GORE® BIO-A® Tissue Reinforcement:
- Supported by an extensive body of positive clinical results over 15 years1
- Proven low recurrence rates in high-risk AWR patients1
- Proven low complication rates in high-risk AWR patients1
- Zero reported complete mesh removals due to infection
Hiatal/paraesophageal hernia repair with GORE® BIO-A® Tissue Reinforcement:
- More than 224,900 hiatal-configured devices have been sold.a
- Clinical literature cites more than 1,980 repairs.1
- Mean follow-up of 5 years has been reported, which is 53-54 months beyond the 6-7 month resorption time period of the mesh.1
- There have been no reports of erosion or infection in the clinical literature.1
