SERALENE non absorbable blue (5/0) DS-18 needle of 75 CM box of 24 sutures - Serag & Wiessner (LO103414) - Delynov

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

SERALENE is a synthetic, monofilament, non-absorbable surgical suture material manufactured by Serag-Wiessner. Its monofilament structure is composed of polyvinylidene fluoride (PVDF), a polymer recognized for its high biocompatibility and extremely smooth surface. This blue surgical suture thread is dyed with solvent blue (no. 61568) to ensure perfect visibility in the surgical field. Offered here in 5/0 calibre, it presents properties similar to those found in certain equivalents such as Filapeau. Its technical design allows for easy handling and consistent knot security, meeting the requirements of the European Pharmacopoeia for sterile non-absorbable sutures.

What are the clinical indications for SERALENE?

SERALENE from Serag-Wiessner is specifically designed for soft tissue approximation or for performing ligatures requiring a non-absorbable thread. Its indications extend to high-precision fields such as microsurgery, ophthalmology, as well as interventions on the central circulatory and nervous systems. In oral and implant surgery, this device is used for flap sutures where low tissue reaction is desired. Polyvinyl fluoride threads can also act as support threads or marking means. Its chemical and physical stability makes it a preferred choice for practitioners requiring a reliable long-term suture.

What are the technical characteristics of the DS-18 needle?

The DS-18 needle equipping this reference LO103414 possesses precise geometric properties for surgery. The code 'DS' designates a 3/8 circle needle equipped with a reverse cutting triangular point. This configuration is ideal for passing through dense or keratinized tissues without causing lateral tearing, as the cutting edge is located on the outer curvature. The number 18 indicates a needle body length of 18mm. Combined with a 75cm thread length, this high-quality surgical steel needle allows for smooth penetration and optimal directional control during trans-gingival passages or when closing extraction sites.

What are the contraindications for the use of this suture?

The use of SERALENE is contraindicated in patients with a known allergy or hypersensitivity to polyvinylidene fluoride or the solvent blue dye (colour index no. 61568). As with any implanted foreign body, the manufacturer Serag-Wiessner specifies that prolonged contact of this device with the biliary or urinary tracts can promote the formation of calculi. It is the surgeon's responsibility to choose the material based on the specific characteristics of the suture and the required surgical techniques. A prior evaluation of the patient's allergic history is essential before any placement of this Class III medical device.

How is the management of a non-absorbable suture handled?

Unlike absorbable materials that disappear through hydrolysis, SERALENE is a 5/0 non-absorbable suture. This means it retains its tensile strength indefinitely in the body and undergoes no significant enzymatic or chemical degradation. In the context of oral surgery, the thread must generally be removed by the practitioner after the initial healing phase, often between 7 and 14 days depending on the protocol. Its smooth monofilament structure considerably reduces the risk of 'wicking' (capillarity), thus limiting the accumulation of dental plaque and food debris along the thread, which greatly facilitates its removal without pain for the patient.

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 carries the CE1014 marking, guaranteeing its compliance with safety and performance requirements for medical devices. As a Class III surgical suture, it undergoes rigorous controls to ensure its sterility and biocompatibility. The material complies with the European Pharmacopoeia monograph concerning non-absorbable threads (fila non resorbilia sterilia). The box contains 24 sterile units, each thread measuring 75cm, thus offering a reliable and standardized solution for operating blocks and dental surgery clinics.

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.
