The precise specifications of medical-grade materials are critical for the design and performance of medical devices, especially those involving tissue contact. Polyglycolic Acid (PGA) sutures, renowned for their absorbable and synthetic nature, require a thorough understanding of their technical parameters. As a leading manufacturer of PGA sutures, we aim to demystify these specifications, helping medical device developers and procurement managers make informed decisions when they decide to buy PGA sutures.

PGA sutures are classified based on various parameters defined by pharmacopoeias like the United States Pharmacopeia (USP). Key specifications include the suture size (USP range), material composition, physical form (braided and coated multifilament), color, and absorption characteristics. Understanding these details is crucial for selecting the appropriate PGA suture for a given surgical application or medical device component.

The USP range indicates the diameter of the suture, typically ranging from 2 to 6-0 for absorbable PGA sutures. The material itself is a homopolymer of glycolide, coated with substances like polycaprolactone and calcium stearate to enhance its passage through tissues. This coating also influences the suture's handling properties and knot security, making it easier for surgeons to use. The violet color, while not always present, offers high visibility, which is beneficial in complex surgical fields.

Crucially, the absorption profile of PGA sutures is determined by hydrolytic degradation. Studies consistently show that PGA sutures retain a significant percentage of their initial tensile strength for the first two to three weeks post-implantation. For instance, approximately 75% of tensile strength remains after 14 days, and 50% after 21 days. Complete absorption typically occurs within 60 to 90 days. This predictable absorption rate is a major advantage over naturally derived materials and makes PGA suitable for applications where medium-term wound support is required.

For medical device manufacturers, sourcing high-quality PGA sutures is essential.
