Overview
Absorbable surgical suture PGA is a synthetic, braided and coated polyglycolic acid suture designed for secure surgical wound closure. It provides high initial tensile strength, predictable hydrolytic absorption and broad applicability across surgical specialties.

Key Benefits

• Biodegradability: Fully absorbable by hydrolysis, eliminating routine suture removal as the material is resorbed over time.
• Strength and Versatility: High initial tensile strength suitable for maintaining tissue approximation during the critical early healing phase; applicable in general, orthopedic, urologic and microsurgical procedures.
• Minimal Tissue Reactivity: High biocompatibility with low inflammatory response to reduce postoperative complications.
• Promotes Optimal Wound Healing: Supports tissue apposition to aid formation of durable, functionally and cosmetically acceptable scars.
• Wide Range of Sizes: Available from fine microsurgical gauges to larger sutures for deep tissue closure.

Technical information summary
PGA is a synthetic absorbable, braided, coated suture composed of polyglycolic acid. It is offered dyed or undyed; when dyed, only approved color additives such as D&C Violet No. 2 are used. The undyed suture appears milk white/beige. PGA combines high initial strength with a resorption profile suited to soft tissue healing.

Technical specifications

• Material: Polyglycolic Acid (PGA), synthetic absorbable, braided, coated suture.
• Available finishes: Dyed and Undyed (undyed: milk white/beige).
• Dye: When dyed, uses FDA-approved color additives (example: D&C Violet No. 2).
• Absorption mechanism: Hydrolysis.
• Tensile strength retention: In vitro linear tensile strength retention after 2 weeks in PBS (pH=7.4) at 37°C ≥ 65% (reported values).
• Total absorption duration: Approximately 50–80 days after implantation.
• Sterilization: ETO gas (ethylene oxide).
• Colour options: Violet or Undyed.
• Size range: USP 8-0 to USP 2.
• Tissue reactivity: Minimal; high biocompatibility to reduce adverse tissue reactions and inflammation.
• Typical applications: Deep tissue closure, general surgery, orthopedics, urology, and microsurgical procedures.
