SERALENE non-absorbable blue (6/0) DSS-15 needle of 50 CM box of 24 sutures - Serag & Wiessner (LO07171T) - Delynov

What is SERALENE non-resorbable blue 6/0?

SERALENE from the brand Serag-Wiessner is a synthetic, monofilament, and non-resorbable surgical suture material. Designed from polyvinylidene fluoride (PVDF), this non-resorbable suture thread is distinguished by its smooth structure that minimizes trauma during passage through tissues. This medical device is tinted blue (solvent blue) for increased visibility during surgery. It meets the strict requirements of the European Pharmacopoeia for sterile non-resorbable sutures. Its 6/0 calibre configuration with a length of 50cm makes it a technical choice for surgeons seeking high handling finesse and long-term biocompatibility.

What are the clinical indications for this suture?

SERALENE is specifically indicated for soft tissue approximation and the performance of ligatures requiring permanent support. According to data from the manufacturer Serag-Wiessner GmbH & Co. KG, its use extends to microsurgery, ophthalmology, as well as interventions on the central circulatory and nervous systems. In daily practice for specialists, this 6/0 blue suture is particularly suited to delicate tissues where minimal inflammatory reaction is sought. The polyvinylidene fluoride material can also be used as a support thread or as a means of surgical marking, offering versatility of use in complex clinical protocols.

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

The DSS-15 needle equipping this reference LO07171T is a 3/8 circle needle featuring an atraumatic reverse cutting triangular point. With a length of 15mm, this geometry is specifically designed for the penetration of dense tissues or thin mucous membranes without the risk of transverse tearing. The atraumatic design allows for precise insertion and fluid passage of the non-resorbable 6/0 suture thread, thereby reducing mechanical stress on the wound edges. Manufactured from high-quality surgical steel, the DSS-15 needle ensures constant rigidity and sharpness throughout the duration of the surgical act, facilitating precision work in microsurgery.

What are the contraindications for the use of SERALENE?

The use of SERALENE is formally contraindicated in patients presenting hypersensitivity or known allergies to polyvinylidene fluoride or to the solvent blue dye (colour index nº 61568). Like any implanted foreign body, this device may promote stone formation if it remains in prolonged contact with the urinary or biliary tracts. It is the practitioner's responsibility to evaluate the choice of suture material based on the specific characteristics of the patient and the surgical technique employed. A careful reading of the instructions is mandatory before any use to respect the restrictions and limits of use defined by the manufacturer Serag-Wiessner.

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

As a non-resorbable surgical suture, SERALENE retains its tensile strength permanently in the body, undergoing no process of hydrolysis or enzymatic degradation. This characteristic requires a rigorous knotting technique to guarantee the stability of the suture over time. The practitioner must adapt their movements to the mechanical properties of the PVDF monofilament to avoid any knot slippage. Although designed to remain in place, removal of the thread may be necessary depending on the established healing protocol. The use of this type of material requires expertise in the choice of 6/0 calibre to ensure tissue approximation without excessive tension.

Who is the manufacturer and what standards are respected?

This suture is manufactured by Serag-Wiessner GmbH & Co. KG, a recognized manufacturer based in Germany. The product is classified as a Class III medical device, meeting the highest safety and performance requirements. It benefits from the CE1014 marking, guaranteeing its compliance with current European regulations. The base material, polyvinylidene fluoride, complies with the European Pharmacopoeia monograph concerning sterile non-absorbable sutures (fila non resorbilia sterilia). The traceability and manufacturing quality of reference LO07171T ensure healthcare professionals a reliable device for their most demanding surgical interventions.

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.
