Composition of the Covetrus White Polyester Cassette Suture 7

The suture is made from long-chain linear polyester fibers, specifically polyethylene terephthalate. These fibers have a high molecular weight and repeating aromatic units as part of their core structure. The thread is braided, sterile, and non-absorbable, designed specifically for advanced surgical applications.

Thanks to its uniform silicone coating, this suture offers greater sliding ability, which facilitates its handling during surgery and improves both tissue penetration and knot security.

Key technical features

• High tensile strength in linear and knotted states.
• Maximum safety in the approximation of tissues under tension.
• Ideal compatibility with prosthetic implants.
• Smooth and secure tissue penetration, with excellent knot retention.

Indications of use

Covetrus 7 White Polyester Cassette Suture is indicated for the ligation and general approximation of soft tissues. It is especially useful in demanding surgical procedures such as:

• cardiovascular surgery
• Neurological surgery
• Ophthalmologic surgery

Thanks to its mechanical properties and in vivo stability, it becomes a reliable choice for interventions that require a permanent suture without loss of strength.

Contraindications

Currently, there are no known specific contraindications for the use of this polyester thread. However, it is recommended to always follow standard surgical protocols and consider individual patient evaluation before use.

Tensile strength and durability

This non-absorbable material maintains its tensile strength over time in the biological environment. It does not suffer substantial loss of mechanical integrity in vivo, making it a durable option for long-term surgical interventions.

Frequently Asked Questions about Covetrus 7 White Polyester Cassette Suture

What types of surgeries require non-absorbable polyester sutures?

Non-absorbable polyester suture is primarily used in cardiovascular, neurological, and ophthalmic surgeries, where prolonged tissue fixation is required.

What is the advantage of the silicone coating on this suture?

The silicone coating significantly improves the thread's sliding ability, making it easier to handle, reducing tissue trauma, and improving knot security.

Is this suture suitable for use with prosthetic implants?

Yes, thanks to its high strength and stability, this suture is ideal for fixation in procedures involving prosthetic implants.

Does suture lose strength over time inside the body?

No, being a non-absorbable material, it maintains its tensile strength without significant deterioration in biological environments.

Can it be used on tissues subjected to high tension?

Yes, it is designed to offer maximum safety in the approximation of tissues under tension, thanks to its braided structure and silicone coating.

Is it sterile at the time of use?

Yes, this product is delivered in sterile condition ready for immediate surgical use.

Can it be used in ophthalmic surgery?

Yes, it is approved for procedures on delicate tissues such as those found in ophthalmic surgery.

What gauge is suture number 7?

Suture number 7 corresponds to a thick gauge, generally used in procedures that require greater tensile strength and prolonged fixation.
