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 after cancer, breast augmentation revision and abdominal wall closure.
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:
10cm x 15 cm
15cm x 20 cm
20cm x 30 cm
TIGR® Matrix was developed to take advantage of the process whereby mechanical load induces remodeling of soft tissue, termed dynamic remodeling. After initial wound closure, the increasing compliance of the mesh results in a gradual transition of load from the mesh to the tissue. Long-term strength retention combined with the dynamic remodeling-based design opens up new opportunities in soft tissue repair.
This design was developed to compensate optimally for the soft tissue’s lack of strength during each phase of wound-healing (closure, granulation and remodeling).1 Accordingly, the mesh degrades in several stages, each with different characteristics, described below.
Characteristic strength and compliance
Multistage mechanics are achieved by arranging two fibers with different degradation characteristics in an interlocking knitting pattern.
Strength and stability of the mesh is high in the initial wound-healing phases (closure and granulation).
Macro porosity throughout the mesh allows for good integration during granulation.
As the granulation phase transitions into the remodeling phase, the elasticity of the mesh gradually increases.
Movement dynamics during remodeling stimulates the regeneration of tissue.
The result of this dynamic remodeling is a more structured, and hence stronger, connective tissue.
