DemeTECH PTFE

Polytetrafluoroethylene (PTFE) — Non-Absorbable Monofilament Surgical Suture

Suture Material

What is Polytetrafluoroethylene (PTFE)?

DemeTECH PTFE Suture is a monofilament synthetic, non-absorbable, sterile surgical suture composed of high-density polytetrafluoroethylene (PTFE). PTFE Suture is provided undyed (White) and contains no coatings, dyes, or additives.

PTFE suture is indicated for use in all types of soft tissue approximation and/or ligation, including dental and general surgeries. PTFE suture is MR Safe.

DemeTECH PTFE suture meets all requirements established by the United States Pharmacopeia (U.S.P.) for Nonabsorbable Surgical Suture, except for diameter.

How It Works

Actions in Tissue

Understanding how PTFE Polytetrafluoroethylene behaves once placed in the body

PTFE suture has been shown in clinical trials to elicit a minimal reaction in tissues. PTFE suture is not absorbed, nor is any significant change in tensile strength retention known to occur in vivo.

The suture is supplied sterile in pre-cut lengths both with and without affixed needles of various straight and curved needle types, making it suitable for a wide range of soft tissue approximation and ligation procedures including dental and general surgery.

01

Minimal Tissue Reaction

Clinical trials confirm that PTFE suture elicits only a minimal reaction in tissues — one of the most biocompatible suture materials available, supporting a low-response healing environment.

02

Not Absorbed — MR Safe

PTFE suture is not absorbed and remains permanently in tissue. Unlike metallic sutures, PTFE is classified as MR Safe, allowing patients to undergo MRI procedures without risk of interaction.

03

Permanent Tensile Strength Retention

No significant change in tensile strength retention is known to occur in vivo — PTFE maintains its mechanical integrity indefinitely, providing permanent wound support.

Characteristics

PTFE Quality Standards

DemeTECH's PTFE suture is a pure monofilament with no coatings, dyes, or additives — offering minimal tissue reaction and permanent MR Safe performance

DemeTECH PTFE Suture is a monofilament synthetic, non-absorbable, sterile surgical suture composed of high-density polytetrafluoroethylene. Provided undyed (White) and containing no coatings, dyes, or additives — PTFE is one of the most chemically inert and biocompatible suture materials available. Classified as MR Safe, it is suitable for a wide range of soft tissue applications including dental and general surgery.

1

Pure PTFE — No Coatings or Additives

Contains no coatings, dyes, or additives — composed entirely of high-density polytetrafluoroethylene, ensuring maximum chemical purity and predictable, consistent material properties.

2

MR Safe

PTFE suture is classified as MR Safe, allowing patients with implanted sutures to undergo MRI procedures without risk of suture heating, migration, or image distortion.

3

Monofilament Structure

Provided as a monofilament — offering smooth, uniform tissue passage, reduced bacterial harbouring potential, and predictable handling characteristics throughout the procedure.

4

Minimal Tissue Reaction

Confirmed in clinical trials to elicit only a minimal reaction in tissues — one of the lowest-reactivity synthetic suture materials available, supporting a clean healing environment.

5

Permanent Tensile Strength

No significant change in tensile strength retention is known to occur in vivo — PTFE maintains its mechanical integrity permanently, ideal for long-term wound closure applications.

6

Dental & General Surgery Applications

Indicated for all types of soft tissue approximation and/or ligation including dental and general surgeries — providing surgeons with a versatile, biocompatible suture option.

Usage

Indications

  • Do not resterilize. Discard open, unused sutures and associated surgical needles. Do not use if package is opened or damaged. Do not use after expiration date.
  • Users should be familiar with surgical procedures and techniques involving PTFE suture before employing for wound closure, as the 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 must be followed with respect to drainage and closure of infected or contaminated wounds.
  • Not indicated for use in ophthalmic surgery, microsurgery, or peripheral neural tissue.
  • This product is not approved in Europe for use on the heart or with the central circulatory and central nervous system.
Safety

Precautions

  • Care should be taken to avoid damage when handling. Avoid crushing or crimping the suture material with surgical instruments such as needle holders and forceps.
  • 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.
  • 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 monofilament sutures.
  • Adverse effects may include wound dehiscence, calculi formation in urinary and biliary tracts, infected wounds, minimal acute inflammatory tissue reaction, pain, edema, and erythema at the wound site. Broken needles may result in extended or additional surgeries or residual foreign bodies. Inadvertent needle sticks may result in the transmission of bloodborne pathogens.
