SERALENE non-absorbable blue (6/0) DSS-13 needle of 50 CM box of 24 sutures - Serag & Wiessner (LO07171L) - Delynov

What is SERALENE non-absorbable blue (6/0)?

SERALENE is a synthetic, monofilament, and non-absorbable surgical suture material manufactured by Serag-Wiessner. Its composition is based on polyvinylidene fluoride (PVDF), a polymer dyed blue (solvent blue, colour index nº 61568) for better visibility. This 6/0 suture thread is distinguished by its monofilament structure which limits capillarity and facilitates sliding through tissues. It complies with the requirements of the European Pharmacopoeia for sterile non-absorbable sutures. This product is delivered in boxes of 24 units, each thread measuring 50cm, offering a reliable solution for interventions requiring durable mechanical stability.

What are the clinical indications for this suture?

SERALENE from Serag-Wiessner is indicated for soft tissue approximation and ligatures requiring a non-absorbable material. Its use extends to demanding fields such as microsurgery, ophthalmology, as well as interventions on the central circulatory and nervous systems. In daily practice, this dental non-absorbable suture thread is particularly suitable for periodontal and implant surgeries where the thinness of the 6/0 calibre allows for precise management of delicate tissues. Polyvinyl fluoride threads can also serve as support threads or marking means during complex procedures.

What are the technical characteristics of the DSS-13 needle?

The DSS-13 needle equipped on this SERALENE suture is a 3/8 circle needle with a length of 13mm. The DSS terminology designates an atraumatic reverse cutting triangular tip. This geometry is specifically designed to penetrate dense tissues or thin mucosa without causing excessive tearing, which is crucial in oral and implant surgery. Its high-quality surgical steel design ensures excellent initial penetration and resistance to bending. This type of needle is considered a standard for precision sutures like the 6/0 dental suture, guaranteeing smooth passage and reduced tissue trauma.

What are the contraindications for the use of this device?

The use of SERALENE is strictly contraindicated in patients with a known allergy to polyvinylidene fluoride or the solvent blue dye (nº 61568). As with any foreign body, the manufacturer Serag-Wiessner specifies that prolonged contact of the suture with the biliary or urinary tracts can promote the formation of calculi. It is imperative that the practitioner adapts the choice of material and the suture technique according to the specific characteristics of the device and the clinical needs of the patient. Careful reading of the instructions for use is essential before any intervention.

How is a non-absorbable suture managed?

As SERALENE is a 6/0 non-absorbable suture thread, it does not undergo degradation by hydrolysis or proteolysis. It maintains its structural integrity and tensile strength indefinitely in the tissues, unless manual removal is performed by the practitioner. During placement, the monofilament nature of PVDF requires particular attention during knot tying to ensure security, although the material is designed for easy handling. This type of suture is preferred when permanent maintenance of the wound edges is necessary or to minimize the local inflammatory reaction often associated with absorbable materials.

Who is the manufacturer and what standards are respected?

This suture is produced by Serag-Wiessner GmbH & Co. KG, a recognized manufacturer based in Germany. The product benefits from a high level of regulatory safety, being classified as Class III according to medical device directives. It carries the CE1014 marking, guaranteeing its compliance with European safety and performance standards. The reference LO07171L corresponds to the brand's quality standards, ensuring traceability and sterility of the material. As a Class III device, SERALENE meets the strictest requirements for long-term surgical implants.

State of the art

Modern synthetic sutures - absorbable or non-absorbable - are central to wound healing in oral surgery. Recent advances focus on reducing post-operative infections.
