Polyglycolic Acid (PGA) is a sterile, absorbable, synthetic multifilament suture composed of braided glycolic acid fibers. The sutures are coated with a blend of polycaprolactone, a copolymer of caprolactone and glycolide, and calcium stearate to ensure smooth tissue passage and enhanced handling.
Available in violet and undyed colors, PGA sutures come in sizes ranging from USP 8/0 to USP 4.
Key Features
-
High initial tensile strength
