What is Nylon Monofilament (NL)?

DemeTECH DemeLON Nonabsorbable Nylon Suture is a nonabsorbable, sterile, surgical suture composed of the long-chain aliphatic polymers Nylon 6. Available as monofilament or multifilament polyamide sutures in black and blue, dyed with FDA listed dyes.

Needle types offered include curved and straight needles, with several lengths, gauges, needle shapes, and suture lengths. DemeLON meets all requirements established by the United States Pharmacopeia for nonabsorbable polyamide surgical sutures.

Indicated for use in general soft tissue approximation and/or ligation, including use in ophthalmic procedures. Intended for long-term use over 30 days. Not approved in Europe for use on the heart or with the central circulatory and central nervous systems.

How It Works

Actions in Tissue

Understanding how DemeLON Nylon behaves once placed in the body

DemeLON Nylon Suture elicits a minimal acute inflammatory reaction in tissues, which is followed by gradual encapsulation of the suture by fibrous connective tissue. While it is not absorbed, progressive hydrolysis of the nylon in vivo may result in a gradual loss of up to 20% of its tensile strength per year.

DemeLON is available in various sizes and may be monofilament or multifilament in form. Supplied sterile in pre-cut lengths, both non-needled and affixed to various needle types, in boxes of one dozen.

Minimal Tissue Reaction

A minimal acute inflammatory reaction occurs in tissues, followed by gradual encapsulation of the suture by fibrous connective tissue — a controlled, low-reactivity response.

Non-Absorbed in Vivo

DemeLON is not absorbed by the body. However, progressive hydrolysis of nylon in vivo may result in a gradual loss of up to 20% of tensile strength per year over time.

Fibrous Encapsulation

Gradual encapsulation of the suture by fibrous connective tissue follows the initial tissue reaction, providing stable integration within the surrounding tissue over time.

DemeTech's Nylon suture is a non-absorbable, sterile surgical suture composed of the long chain aliphatic polymer Nylon 6.6. Following placement, gradual encapsulation of the suture by fibrous connective tissue occurs. DemeLON is available as monofilament or multifilament, supplied in black and blue with FDA listed dyes, in various sizes — meeting all USP requirements for nonabsorbable polyamide surgical sutures.

Long-Chain Aliphatic Polyamide

Composed of the long-chain aliphatic polymer Nylon 6.6, providing consistent material properties and predictable in vivo behaviour as a permanent nonabsorbable suture.

Easy Tissue Passage

Easy passage through tissues due to its low frictional coefficient — reducing drag and tissue trauma while maintaining excellent handling characteristics throughout the procedure.

Minimal Tissue Reactivity

Elicits only a minimal acute inflammatory reaction in tissues, followed by gradual fibrous encapsulation — supporting a stable, low-reactivity tissue environment.

Coated & Excellent Elasticity

Coated to improve handling and available as tightly braided filaments. Excellent elasticity makes DemeLON particularly well suited to skin closures where flexibility is required.

Black & Blue Colours

Available in black and blue, dyed with FDA listed dyes. Supplied sterile in pre-cut lengths, non-needled and affixed to curved and straight needle types, in boxes of one dozen.

USP Compliant

Meets all requirements established by the United States Pharmacopeia for nonabsorbable polyamide surgical sutures. Intended for long-term use over 30 days, including ophthalmic procedures.

Usage

Indications

Do not resterilize. Discard open, unused sutures.
Prolonged contact of this or any other suture with salt solutions, such as those found in the urinary or biliary tracts, may result in calculus formation.
Users should be familiar with surgical procedures and techniques involving nonabsorbable sutures before employing DemeLON for wound closure, as risk of wound dehiscence may vary with the site of application and the suture material used.
As any foreign material in the presence of bacterial contamination may enhance bacterial infectivity, acceptable surgical practice must be followed with respect to drainage and closure of infected or contaminated wounds.
Do not reuse. The reuse of single-use devices can cause cross contamination and affect the device safety, performance and effectiveness, exposing patients and staff to unnecessary risk.
This product is not approved in Europe to be used on the heart or with the central circulatory and central nervous systems.
Contraindication: Due to the gradual loss of tensile strength which may occur over prolonged periods in vivo, DemeLON should not be used where permanent retention of tensile strength is required, as in fixation of intraocular lenses or synthetic vascular grafts.

Safety

Precautions

When 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 holders.
As with any suture material, adequate knot security requires the accepted surgical technique of flat, square ties, with additional throws as warranted by surgical circumstance and the experience of the surgeon. The use of additional throws may be particularly appropriate when knotting monofilaments.
Adverse effects associated with the use of this device include: wound dehiscence, gradual loss of tensile strength over time, calculi formation in urinary and biliary tracts when prolonged contact with salt solutions occurs, enhanced bacterial infectivity, minimal acute inflammatory tissue reaction, pain, edema, and erythema at the wound site.
