Polyglactin 910 Sutures

What is Polyglactin 910 (Petcryl 910)?

Polyglactin 910 is a synthetic absorbable surgical suture constructed as a braided multifilament from a copolymer of glycolide and L-lactide. Marketed by Dolphin Sutures under the brand name Petcryl 910, it is intended for soft tissue approximation and ligation where a temporary, absorbable wound support is appropriate. Dolphin Sutures was the first Indian brand to introduce a polyglactin 910 range in India, and the product is manufactured under an ISO 13485 certified quality management system.

Composition and coating

The suture is formed from a copolymer of approximately 90% glycolide and 10% L-lactide. The braided filament is coated with a layer of poly (glycolide-co-L-lactide) together with calcium stearate. This coating is designed to produce a smooth surface that supports comfortable tissue passage and consistent knot run-down, while the braided structure contributes to handling characteristics familiar to surgeons who use coated absorbable sutures.

Absorption and tensile strength

Petcryl 910 is absorbed by hydrolysis. In use, the suture retains approximately 70% of its initial tensile strength at around two weeks after implantation, with tensile strength declining progressively thereafter as absorption proceeds. Because the absorption pathway is predictable, the suture provides temporary wound support during the early healing phase and does not require removal in buried applications. The material elicits a slight (Grade 1) tissue reaction during absorption.

Presentations

Petcryl 910 is available in USP sizes 6-0 to 4, in both violet (dyed) and undyed presentations. It is supplied armed with 300 series alloy steel needles across a range of profiles and lengths, and as needleless presentations where required. A rapid-absorption variant is also available for applications requiring shorter-term wound support.
