LINEX - Monofilament Nylon Suture

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.


catalog   Instructions for Use


  • 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.
  • LINEX sutures pass through tissues easily and since the suture is monofilament knotting is very easy. The tissue adherence to the suture is absolutely nil.
  • LINEX sutures have excellent knot security and it has easy knot placement.
  • LINEX sutures are available with needles made from 300 series alloy steel for superior strength, sharpness and performance.
  • LINEX sutures have excellent tensile strength and the sutures do not elongate while knotting.

Brand name: LINEX®

Material: Monofilament Polyamide (Nylon)
Non – absorbable surgical suture. U.S.P

Linex® suture is an extremely strong very pliable surgical nylon. It has high in vivo tensile strength, does not support bacterial growth & has the further advantages of being remarkably smooth & easy to handle.
Entire detail of the product range is contained in the catalogue. Linex® complies with the requirements of the United States Pharmacopoeia for non absorbable surgical suture.

Linex® 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.   

Suture should be selected and implanted depending on the patient’s condition, surgical experience, surgical technique and wound size.

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.

None known

User should be familiar with surgical procedure and techniques involving non – absorbable sutures before employing Linex® for wound closure as a risk of wound dehiscence may vary with the site of application and the suture material used.
As with any foreign body, prolonged contact of any suture with salt solutions, such as those found in the urinary or biliary tracts may result in calculus formation. Acceptable surgical practice should be followed for the management of infected or contaminated wounds.

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. Avoid crushing or crimping damage due to surgical instruments such as forceps or needle holders.
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. The use of addition throws is particularly appropriate when knotting Mono filament polyamide sutures.
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 point area could impair the penetration performance and cause fracture of the needle. Grasping at the butt or attachment end could cause bending or breakage. Reshaping the needles may cause them to loose strength and make less resistant to bending and breaking.
Users should exercise caution when handling surgical needles to avoid inadvertent needle stick injury. Discard the needles after use in container labeled as “SHARP”

Adverse reactions:
Adverse reactions associated with the use of this device include: minimal initial inflammatory tissue reaction and transient local irritation at the wound site. Like all foreign bodies Linex® may potentate an existing infection.

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 below 25 ºC, away from moisture and direct heat. Do not use after expiry date.
