TIGR® Matrix

TIGR® Matrix is the world’s first long-term resorbable, 100% synthetic, surgical mesh. Its unique technology consisting of dual-stage degradation and full resorption, paired with ease of use, is a significant step forward in surgical mesh technology. Since it uses polymers common in medical devices since the 1970’s, and is 100% synthetic, its components are more than well documented and clinically proven.

Today, TIGR® Matrix finds use in many applications, e.g. breast reconstruction and abdominal wall reinforcement.​​​​

TIGR® Matrix Surgical Mesh is knitted from two different synthetic resorbable fibers, possessing different degradation characteristics. The fast-resorbing fiber, making up approximately 40% of the matrix by weight, is a copolymer of glycolide, lactide, and trimethylene carbonate. The slow-resorbing fiber, making up approximately 60% of the matrix by weight, is a copolymer of lactide, and trimethylene carbonate.

Both fibers degrade by bulk hydrolysis once implanted, resulting in a decreasing strength retention followed by mass loss of the fibers. In vitro testing showed that the fast-resorbing fiber (glycolide, lactide, and trimethylene carbonate) loses its mechanical strength after 2 weeks and in vivo studies in the abdominal wall of sheep showed that the fast-resorbing fiber is fully absorbed after 4 months. The same in vitro testing showed that the slow-resorbing fiber (lactide, and trimethylene carbonate) maintains its mechanical strength for 6 months and in vivo studies in the abdominal wall of sheep indicated that the slow-resorbing fiber is absorbed after approximately 36 months.

TIGR® Matrix Surgical Mesh received 510(k) clearance by the FDA in 2010 and carries the CE-mark since 2011.

TIGR® Matrix is currently available in 3 sizes:
NSTM1015E, 10 x 15 cm
NSTM1520E, 15 x 20 cm
NSTM2030E, 20 x 30 cm
