Description
The Medtronic Novafil monofilament polybutester suture is available from MedicalEx in the configurations listed below. Polybutester fiber gives this nonabsorbable monofilament an elastic handling character that differs from polypropylene, with permanent tensile support in blue or clear.
- Nonabsorbable polybutester monofilament
- Permanent tensile strength
- Blue or clear strands, sizes 7-0 through 2
- Elastic elongation character for controlled tissue handling

Main Description
Novafil sutures are nonabsorbable monofilament strands composed of polybutester fiber. Polybutester is known for an elastic quality that lets the strand elongate under load and recover, a handling trait surgeons use where tissue swells after closure. The strand is uncoated, retains its tensile strength permanently and is supplied in blue or clear across USP sizes 7-0 through 2. Medtronic indicates the line for general soft tissue approximation and ligation. The line is contraindicated in patients with known sensitivities or allergies to its components, per the manufacturer's labeling.
Features and Benefits
- Elastic monofilament – Polybutester elongates under tension and recovers, accommodating postoperative tissue swelling better than rigid strands.
- Permanent support – The nonabsorbable strand keeps its strength indefinitely for long-term approximation.
- Smooth passage – The monofilament surface glides through tissue with low drag and no braid interstices.
- Visibility choice – Blue strands read easily in the field, and clear strands are available for discreet closure.

Why Choose This Product
Polybutester occupies its own niche: a permanent monofilament with give, chosen when a rigid strand would cheese-wire swelling tissue. Facilities that stock it do so because no polypropylene or nylon strand replicates its elongation behavior.
- Elongation advantage – Controlled stretch under load is the differentiator, helping closures ride out edema without cutting tissue.
- Permanent yet forgiving – Strength retention is indefinite while the strand stays tissue-friendly in handling.
- Full working range – Sizes 7-0 through 2 cover fine through general closure without leaving the family.
Frequently Asked Questions
How is polybutester different from polypropylene?
Both are nonabsorbable monofilaments with permanent strength, but polybutester has an elastic elongation character that polypropylene lacks. That give is why surgeons pick it for tissue expected to swell after closure.
Does this strand absorb over time?
No. It is a nonabsorbable material and retains tensile strength permanently, so it is used where long-term approximation is required.
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.
