What is SERALENE blue (5/0) from Serag-Wiessner?

SERALENE is a high-precision synthetic surgical suture material designed by the manufacturer Serag-Wiessner. This device is a non-absorbable monofilament made from polyvinylidene fluoride. Its monofilament structure provides a smooth surface, limiting tissue trauma during thread passage. Dyed blue (solvent blue, colour index nº 61568) for optimal visibility in the surgical field, this USP 5/0 gauge thread has a length of 50 cm. It is specifically developed to meet the requirements of microsurgery and interventions requiring great handling finesse. This product complies with European Pharmacopoeia requirements for sterile non-absorbable sutures.

What are the contraindications for the use of SERALENE?

The use of the SERALENE device is strictly contraindicated in patients with a known allergy to any of its components, notably polyvinylidene fluoride or the solvent blue dye. As with any foreign body, the manufacturer specifies that prolonged contact of this suture with the biliary or urinary tracts may promote the formation of calculi. It is the practitioner's responsibility to evaluate the choice of material based on the specific characteristics of the patient and the surgical technique employed. Careful reading of the instructions is imperative before any intervention to ensure the product's suitability for the clinical case being treated.

What are the precautions related to its non-absorbable nature?

As a non-absorbable suture, SERALENE maintains its tensile strength permanently in the tissues and does not undergo a degradation process by hydrolysis. This characteristic requires the practitioner to plan, if necessary, a subsequent step for the removal of the stitches once healing is achieved. During handling, it is recommended to take standard precautions related to synthetic monofilaments to ensure knot security. The choice of suture technique must take into account the mechanical properties of polyvinylidene fluoride to avoid any knot slippage or excessive tension on the soft tissues.

SERALENE non-absorbable blue (5/0) DS-15 needle 50 CM box of 24 sutures - Serag & Wiessner (LO101713) - Delynov

Q: What are the clinical indications for this suture?

SERALENE from Serag-Wiessner is indicated for soft tissue approximation and ligations requiring the use of a non-absorbable thread. In surgery, its use is particularly suited to fields requiring high precision such as the central nervous and circulatory systems, ophthalmology, as well as microsurgery. For dental surgeons and implantologists, it constitutes a choice solution for delicate sutures of the oral mucosa, where dimensional stability and the lack of capillarity of the monofilament are crucial. It can also serve as a support thread or a marking tool. Its use guarantees prolonged maintenance of the wound edges, essential in reconstruction or implantation protocols.

Q: What are the technical characteristics of the DS-15 needle?

This reference LO101713 is equipped with a DS-15 needle made of high-quality surgical steel. The DS nomenclature designates a 3/8 circle needle equipped with a triangular reverse cutting tip. This geometry is ideal for passing through dense or keratinized tissues without causing accidental tearing, offering precise and controlled penetration. The number 15 indicates a needle length of 15 mm. Associated with the 5/0 gauge and the 50 cm thread length, this configuration allows for easy manipulation in the restricted spaces of the oral cavity, ensuring maximum safety during stitch placement.

Q: Who is the manufacturer and what standards are met?

SERALENE is manufactured by Serag-Wiessner GmbH & Co. KG, a company based in Naila, Germany, recognized for its expertise in suture devices. This product benefits from a rigorous regulatory classification as a Class III medical device, attesting to its high level of safety for invasive interventions. It bears the CE1014 marking, guaranteeing its compliance with current European requirements. Manufacturing respects the standards of the European Pharmacopoeia monograph for sterile non-absorbable sutures (fila non resorbilia sterilia), thus ensuring healthcare professionals a reliable, sterile, and high-performance material for their daily surgical acts.

The SERALENE suture by Serag-Wiessner GmbH & Co. KG is a non-absorbable monofilament synthetic medical device, indicated for oral surgery and implantology where prolonged material stability is required.

What is SERALENE non-absorbable blue (5/0)?

SERALENE, manufactured by Serag-Wiessner, is a synthetic, non-absorbable monofilament surgical suture. Made from polyvinylidene fluoride (PVDF), this material is distinguished by its smooth structure which limits bacterial adhesion and facilitates passage through tissues. Dyed blue (solvent blue) for increased visibility in the surgical field, this 5/0 calibre thread meets the requirements of the European Pharmacopoeia for sterile non-absorbable sutures. Purchasing a monofilament suture of this type is particularly indicated for practitioners seeking high chemical stability and high biocompatibility during prolonged healing phases.

What are the clinical indications for this suture?

This blue surgical suture is intended for soft tissue approximation and ligatures requiring permanent or long-term support. In oral and implant surgery, it is used for site closure, microsurgery, and ophthalmic procedures. The manufacturer Serag-Wiessner GmbH & Co. KG specifies that SERALENE can also be used in the central circulatory and nervous systems. Its monofilament structure avoids the wicking effect, making it a relevant choice for environments exposed to oral flora. Polyvinyl fluoride threads can also serve as stay sutures or marking tools according to clinical needs.

What are the technical characteristics of the DS-15 needle?

The DS-15 needle equipped on this reference LO101713 has specific properties for fine surgery. The DS code designates a 3/8 circle needle with a triangular reverse cutting point. This geometry is ideal for penetrating dense or keratinized tissues without causing accidental tissue tearing, as the cutting edge is oriented towards the outside of the curvature. The number 15 indicates a length of 15 mm, offering an optimal compromise between maneuverability and control when handling a 50cm long thread. This surgical steel needle guarantees precise and constant penetration throughout the monofilament surgical suture procedure.

What are the contraindications for the use of this device?

The use of SERALENE is strictly contraindicated in patients with known hypersensitivity or allergies to polyvinylidene fluoride or the solvent blue dye (colour index nº 61568). As with any implanted foreign body, the manufacturer warns that prolonged contact with bile or urinary tracts can promote stone formation. It is imperative that the practitioner selects the suture material taking into account the specific characteristics of the product and the technical requirements of the intended intervention to minimize the risk of post-operative complications.

What are the precautions related to the non-absorbable nature of the thread?

As SERALENE is a non-absorbable material, it retains its mechanical strength indefinitely after implantation. Unlike absorbable materials, it does not undergo hydrolysis. Post-operatively, stitch removal must be planned by the surgeon once wound edge healing is achieved. Due to its very smooth monofilament surface, particular attention must be paid to knot security; it is often recommended to perform additional throws to prevent slippage. This thread can be considered an equivalent to Filapeau in certain skin applications, although its PVDF properties give it specific flexibility and inertia sought after in high-tech surgical suture purchases.

Who is the manufacturer and what standards are respected?

This medical device is manufactured by Serag-Wiessner GmbH & Co. KG, a recognized manufacturer based in Germany. The product is classified as a Class III medical device, which corresponds to the highest regulatory requirement level for surgical implants. It bears the CE1014 marking, guaranteeing its compliance with European safety and performance standards. Each box of 24 sutures is subject to rigorous controls to ensure sterility and consistent quality of the components, including the 50cm thread and the DS-15 needle. Compliance with the « fila non resorbilia sterilia » monograph ensures practitioners have reliable material for their daily surgical procedures.

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.
