Linex is the brand name of nylon sutures manufactured by Dolphin Sutures. Nylon sutures are also known as polyamide sutures. Nylon sutures are monofilament sutures and are remarkably smooth, soft and gives excellent knot security.

Nylon sutures are non-absorbable sutures and possess excellent tensile strength. Nylon sutures are available in black colour. Nylon sutures have excellent knot security properties and can be easily removed with no tissue adherence. These sutures are infection resistant.

Nylon sutures are widely used for general closure, skin and plastic surgery. They are usually not recommended for attachment of artificial prostheses in cardiovascular surgery. They also do not support infection and maintain tensile strength indefinitely in tissues.

Nylon sutures are available in black colour.

  • Features

    • Nylon suture is a monofilament non-absorbable surgical suture.
    • Nylon sutures are available from U.S.P. size 2 to size 10-0. Suture is available in black colour.
    • Nylon sutures are composed of polymers made from 100% homo polymer of polyamide grade 6.6.
    • Nylon sutures are ideal for skin closures since they do not exhibit tissue adherence.
  • Advantages

  • Usage


    Material: Monofilament Polyamide (Nylon)

    Non Absorbable Surgical Suture U.S.P



    Linex® suture is a non-absorbable, sterile, surgical monofilament suture composed of long chain aliphatic polymers nylon 6.

    It has high in-vivo tensile strength, does not support bacterial growth. Linex® sutures are dyed with Logwood extract, usfda approval number §73.1410.

    Available in abroad range of sutures sizes and lengths, is either non-needled or attached to standard stainless steel needles of varying types and sizes.

    Linex® complies with the “Non absorbable Suture (Polyamide Surgical Suture)” requirements as per the United States Pharmacopeia (U.S.P). The needles are attached permanently to the suture. Entire detail of the product range is contained in the catalogue.



    Polyamide (Nylon) suture is suitable for closing skin sub cuticular layers. Its high degree of elasticity contributes to its great strength in the fine sizes, enabling the plastic surgeons, the micro surgeons & the Ophthalmologists to tie secure knots.



    The suture should be selected and implanted depending on patient’s condition, surgical experience, surgical technique, and wound size. Normally the skin sutures are removed within 30 days depending on wound condition. The decision of physician is final in removing the skin sutures.


    Linex® suture elicits a minimal initial inflammatory reaction in tissues which is followed by gradual encapsulation of the suture by fibrous connective tissue. Linex® suture is not absorbed nor is it subjected to degradation or weakening by the action of tissue enzymes. Due to its relative biological inertness it is recommended for use where the least possible suture reaction is desired. As a monofilament it has been successfully employed in surgical wounds which subsequently become infected or contaminated where it can minimize later sinus formation and suture extrusion.

    Its lack of adherence to tissue Linex® is effective as a pull out suture.



    Adverse reactions associated with the use of Linex® include transitory local irritation at the wound site or transitory inflammatory foreign body response. Like all foreign bodies Linex® may potentate an existing infection.



    Due to gradual loss of tensile strength which may occur due to prolonged periods in vivo, nylon sutures should not be used where permanent retention of tensile strength is required. The product is not recommended to be used in central nervous system and circulatory system. The use of this suture is contraindicated in patients with known sensitivities or allergies to nylon.


    1. Surgeons should be familiar with surgical procedures and techniques involving non-absorbable sutures before employing Polyamide suture for wound closure, as the risk of wound dehiscence may vary with the site of application and the suture material used.
    2. In surgery of the urinary or biliary tract, care should be taken to avoid prolonged contact of this or any other suture with salt solution, to prevent calculus formation.
    3. For single use only. Do not reuse, reprocess or re-sterilize. Reuse, reprocessing or re‐sterilization may compromise the structural integrity of the device and/ or lead to device failure which, in turn, may result in patient injury and illness.
    4. Reuse, reprocessing or re‐sterilization may also create a risk of contamination of the device and/or cause patient infection or cross‐infection, including, but not limited to, the transmission of infectious disease(s) from one patient to another.
    5. Contamination of the device may lead to injury, illness of the patient.



    1. Acceptable surgical practice should be followed for the management of contaminated or infected wounds.
    2. In handling this suture material, care should be taken to avoid damaging the surface of the material with surgical instruments as this could lead to fracture of the material in use.
    3. Avoid crushing or crimping damage due to surgical instruments such as forceps or needle holders.
    4. Adequate knot security requires the standard surgical technique of flat and square ties with additional throws as indicated by surgical circumstances and the experience of the surgeon.
    5. The use of addition throws is particularly appropriate when knotting Mono filament polyamide sutures.
    6. Care should be taken to avoid damage while handling surgical needles. Grasp the needle in an area of one third (1/3) to one half (1/2) of the distance from the attachment end to the sharp point.
    7. Grasping in the sharp point area could impair the penetration performance and cause fracture of the needle.
    8. Grasping at the butt or attachment end could cause bending or breakage.
    9. Reshaping the needles may cause them to loose strength and make less resistant to bending and breaking.
    10. Users should exercise caution when handling surgical needles to avoid inadvertent needle stick injury.
    11. Discard the used needles appropriately.



    Linex® sutures are sterilized by ethylene oxide. Do not re – sterilize! Do not use if package is opened or damaged! Discard opened unused sutures.



    Recommended storage condition 10oC-35°C, away from moisture and direct heat. Do not use after expiry date.



    Discard used sutures and needles contaminated with blood in the container meant infectious waste. Unused expired pouches should be incinerated.
