DAYLON® Polyamide, synthetic, non-absorbable, monofilament, sterile surgical sutures

Daylon® Doğsan Non-absorbable Surgical Suture

Daylon is a synthetic, non-absorbable, sterile surgical monofilament suture composed of the long chain aliphatic polymers polyamide. Daylon is dyed blue for higher visibility.

Daylon meets all requirements for non-absorbable surgical sutures specified by the European Pharmacopoeia (EP) and United States Pharmacopoeia (USP).


Daylon is indicated for use in general soft tissue approximation and/or ligation. Its pliability and low tendency to swell makes Daylon very suitable for all types of skin sutures. Daylon can also be used as holding sutures and for marking purposes.  Fine sizes of Daylon USP 11/0 to USP 8/0 (EP 0.1 – 0.4) are particularly suitable for microsurgery and ophthalmic surgery.


Daylon elicits a minimal acute inflammatory reaction in tissue, which is followed by a gradual encapsulation of the suture by fibrous connective tissue. Daylon is not absorbed, progressive hydrolysis of the suture in vivo may result in gradual loss of tensile strength over time.


Daylon is available dyed black in USP sizes 10/0 to 8/0 (EP 0.1 – 0.4) and dyed blue in USP sizes 6/0 to 2 (EP 0.7 – 5). The sutures are supplied sterile, in precut lengths as non-needled or affixed to needles (one or two) in box containing a dozen pouches. Please refer to catalog for details.


The product should be kept dry and clean. Keep away from direct sunlight and do not use products after expiry (“use by”) date


Due to the gradual loss of tensile strength which may occur over prolonged periods in vivo, polyamide suture should not be used where permanent retention of tensile strength is required. Polyamide sutures are not intended for use in central vascular or nervous systems.


Users should be familiar with surgical procedures and techniques involving non-absorbable sutures before
Daylon for wound closure, as 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.
Do not re-sterilize.
This device is single use. Known hazards with reuse or re-sterilization of opened/original packages of the device are cross contamination, infection and trauma.
Discard opened packages and unused sutures.
Do not use opened or damaged products.


In handling this or any other suture material, care should be taken to avoid damage from handling.
Avoid crushing or crimping damage due to application of surgical instruments such as forceps or needle
As with any suture material, adequate knot security requires the accepted surgical technique of flat and
square ties with additional throws as warranted by surgical circumstance and the experience of the surgeon.
When lasering and electro-cautering is used, avoid damaging the sutures. Users should avoid electrocautering and/or laser on suture.
To avoid damaging needle points and swage areas, grasp the needle in an area one-third (1/3) to one-half
( 1 /2) of the distance from the swaged end to the point. Reshaping needles may cause them to lose strength and be less resistant to bending and breaking.
Users should exercise caution when handling surgical needles to avoid inadvertent needle sticks.
Discard used needles in " sharps" containers.
When polyamide threads are used in ophthalmic surgery, patients require prolonged observation, corneal polyamide sutures should be removed after 3 to 12 months and laser radiation accelerates the tissue breakdown of polyamide sutures.


Adverse effects associated with the use of this device include wound dehiscence, calculi formation in urinary and biliary tracts when prolonged contact with salt solutions such as urine and bile occurs, infection, minimal acute inflammatory tissue reaction, and transitory local irritation at the wound site. Broken needles may cause complications in extended or additional surgeries or residual foreign bodies. Inadvertent needle sticks with contaminated surgical needles may result in the transmission of blood borne pathogens
