Product overview
Absorbable surgical suture PDO is a polydioxanone monofilament synthetic absorbable suture designed for surgical wound closure. It provides controlled biodegradation, sustained tensile strength during early healing and easy handling for secure knotting and reduced tissue trauma. Suitable for general surgery, plastic surgery and gynecology, it is indicated for subcutaneous layers and delicate skin closure.

Benefits

• Biodegradability: made from polydioxanone, gradually absorbed by the body, eliminating the need for suture removal.
• Strength and stability: retains significant tensile strength during the critical early healing period, reducing risk of wound dehiscence.
• Ease of use: monofilament structure ensures smooth passage through tissue, low drag and reliable knot security.
• Promotes wound healing: acts as a scaffold supporting tissue regeneration with minimal scarring.
• Versatile applications: suitable for subcutaneous layers and delicate skin closure across multiple surgical specialties.

Technical data
PDO (polydioxanone) monofilament synthetic absorbable suture prepared from the polyester poly(p-dioxanone). Empirical molecular formula: (C4H6O3)x. Dye options may include D&C Violet No. 2. Polydioxanone is nonantigenic, nonpyrogenic and elicits only slight tissue reaction during absorption. PDO meets the requirements of the European Pharmacopoeia (EP) for synthetic absorbable monofilament sutures.

Absorption
In vitro linear tensile strength retention after 4 weeks in PBS (pH = 7.4) at 37℃ ≥ 60% BSR. Complete absorption between 120 and 180 days.

Standard
European Pharmacopoeia (EP)

Sterilization
ETO gas (ethylene oxide)

Colour
Violet or undyed

Range
Available in USP sizes 7-0 to 2

Conclusion
PDO absorbable surgical suture offers controlled biodegradation, sustained support during healing and easy handling, suitable for a wide range of surgical procedures.
