PDS (SURGICAL)
In stock
In veterinary medicine, PDS (Polydioxanone Suture) is a sterile, monofilament, synthetic absorbable surgical suture. It is widely recognized as the premier long-lasting absorbable material used to close internal tissues that require prolonged structural support during the healing process.

Specs & features.
PDS is synthesized from the polyester polymer poly-p-dioxanone. It is manufactured as a single, smooth strand (monofilament) rather than a braided bundle. The thread is typically dyed violet to provide strong visual contrast against red animal tissues, though undyed (clear) versions are available for superficial cosmetic closures. PDS degrades in the body via chemical hydrolysis (the breakdown by water in tissue fluids), rather than enzymatic digestion. This ensures a highly predictable absorption rate that triggers minimal localized tissue inflammation.

- Extended Tensile Strength Retention: Retains approximately 70% of its original strength at 2 weeks, 50% at 4 weeks, and 25% at 6 weeks post-implantation, providing a long safety window for slow-healing animal tissues.
- Monofilament Surface Architecture: The smooth, single-strand design minimizes tissue drag (the "sawing" effect) during placement and lacks microscopic crevices, preventing bacteria from hitchhiking along the line.
- Predictable In-Vivo Absorption: Completely absorbed via tissue fluid hydrolysis within 182 to 238 days, leaving behind no permanent foreign body material inside the patient.
