Pre-Clinical and Clinical Data

Outcomes: Hernia Recurrence Rates

889 patients in clinical literature, including a multicenter prospective clinical study, provide data to show GORE® BIO-A® Tissue Reinforcement is an excellent choice in soft tissue repair.* GORE® BIO-A® Tissue Reinforcement has low recurrence rates when used in hiatal hernia repair.1,2,3

Pre-Clinical Data

GORE® BIO-A® Tissue Reinforcement exhibited higher degree of cellular and vascular in-growth and collagen deposition than three commonly used biologic meshes in a sterile field. The use of a polyglycolic acid/trimethylene carbonate absorbable mesh results in a favorable tissue response.4
