Medtronic Biosyn Monofilament Absorbable Sutures with Glycomer 631 Synthetic Polyester Sterile

The Medtronic Biosyn monofilament absorbable suture is available from MedicalEx in the configurations listed below. The Glycomer 631 strand blends glycolide, dioxanone and trimethylene carbonate for strong initial tension that carries through the critical healing period.

• Glycomer 631 synthetic polyester monofilament
• 75 percent tensile strength at two weeks, 40 percent at three weeks
• Absorption in about 90 to 110 days
• Minimal memory for easy handling, violet or undyed

Main Description

Biosyn sutures are prepared from Glycomer 631, a synthetic polyester composed of glycolide (60 percent), dioxanone (14 percent) and trimethylene carbonate (26 percent). The formulation is designed for excellent initial strength and in-vivo strength retention over the critical wound healing period. Medtronic rates tensile strength at 75 percent after two weeks and 40 percent after three weeks, with absorption complete in 90 to 110 days. The monofilament shows minimal memory, which improves handling ease and knot security compared with stiffer monofilaments. The line is indicated for general soft tissue approximation and ligation in sizes 6-0 through 1, but not for cardiovascular or neurological surgery.

Features and Benefits

• High initial strength – The Glycomer 631 blend starts strong, giving closures a margin during the first critical days.
• Low memory handling – Minimal pack memory means the strand lies where it is placed instead of springing back.
• Mid-term profile – Ninety to 110 day absorption matches tissues that heal over a standard two to three week support need.
• Monofilament surface – A single smooth strand passes through tissue with low drag and no braid interstices.

Why Choose This Product

This is the mid-term monofilament for services that want absorbable support without a braid, in the size range general surgery uses most. Documented retention of 75 percent at two weeks gives a clearer support picture than lines that publish only absorption times.

• Published retention curve – Specific two and three week strength figures let surgeons match the strand to the tissue instead of guessing.
• Handles like it should – Minimal memory is the practical differentiator at the table, where stiff monofilaments slow down closures.
• Balanced profile – Strength, absorption and handling sit in the middle of the absorbable range, suiting the broadest set of general cases.

Frequently Asked Questions

What tissues is this line suited to?

It is indicated for general soft tissue approximation and ligation where about three weeks of support is appropriate. It is not indicated for cardiovascular or neurological surgery.

How long until the strand is gone?

Absorption is complete in about 90 to 110 days by hydrolysis. Tensile strength falls to about 40 percent by three weeks, well before the strand itself disappears.

How should sutures be stored?

Store sutures in their original packaging in a cool, dry place away from direct heat and light. Use stock in expiry order and do not use any suture whose package is opened or damaged, since sterility cannot be assured.

What do the suture size numbers mean?

USP suture sizes run from fine to heavy: more zeros mean a finer strand, so 7-0 is finer than 5-0, which is finer than 3-0. Sizes then rise through 0, 1, 2 and heavier for large tissue work. The variant label states the exact size of each configuration.

Can a suture be resterilized or reused?

No. These are sterile single use devices, and an opened or expired suture must be discarded. Resterilization is not permitted and compromises both sterility and material performance.
