Tissue Reaction:

PTFE (polytetrafluoroethylene) suture is known to cause a minimal reaction in tissues, based on clinical trials. This ensures reduced complications post-operatively related to suture material.

Tensile Strength & Absorption:

• The PTFE suture is not absorbed by the body.
• No significant change in its tensile strength retention is observed when placed inside the body. This means the suture remains durable and maintains its integrity over time.

Availability & Packaging:

• Variety: The DemeTECH PTFE Suture is available in multiple sizes, catering to diverse surgical needs.
• Sterilization & Packaging: The suture is provided in a sterile condition to ensure patient safety.
• Delivery: It comes in pre-cut lengths, both with and without needles attached. The attached needles can be of various types, both straight and curved, to suit different surgical procedures.

Summary:

DemeTECH's PTFE Suture is a reliable choice for surgeries requiring minimal tissue reaction and durable wound support. Its versatility in terms of sizes and needle options makes it suitable for a wide range of surgical applications.

Intended Use:

PTFE (polytetrafluoroethylene) suture is designed for soft tissue approximation and/or ligation. This makes it apt for a variety of surgical procedures, including those related to dental and general surgeries.

Warnings:

• Resterilization is not recommended. Unused sutures and needles should be discarded.
• Surgical professionals must be acquainted with the techniques and procedures involving PTFE sutures.
• Prolonged exposure to salt solutions, as in the urinary or biliary tracts, may lead to calculus formation.
• Standard surgical practices should be adhered to, especially when dealing with infected or contaminated wounds.

Precautions:

• Handle sutures with care to avoid any damage.
• Refrain from causing crushing or crimping damage with surgical instruments.
• Potential complications with PTFE sutures include infections, erythema, foreign body reactions, inflammatory reactions, and wound dehiscence.
• To avoid needle damage, grasp it between one-third to one-half of its distance from the swaged end.
• Care should be taken to prevent needle stick injuries. Used needles should be discarded appropriately.
• Proper knotting techniques are crucial for maintaining suture integrity.

Contraindications:

PTFE sutures are not suitable for ophthalmic surgery, microsurgery, or surgeries involving peripheral neural tissue.

Adverse Reactions:

• Possible complications include wound dehiscence, calculus formation in urinary and biliary tracts, infections, inflammatory reactions, pain, swelling, and erythema at the surgical site.
• Broken needles might necessitate additional surgeries.
• Contaminated needle stick injuries pose a risk of transmitting bloodborne pathogens.

Delivery Form:

• PTFE sutures are sterilized using ethylene oxide.
• They should not be resterilized.
• Packages that are opened or damaged should not be used.
• Sutures should not be used past their expiration date.

Conclusion:

While PTFE sutures offer several advantages, surgeons should be fully aware of their properties, potential complications, and the best practices for their use to ensure optimal patient outcomes.
