PDO Lifting Threads
Description
N-COG Multi Cogged Thread 21G/100mm (6 PCS.) is a premium polydioxanone (PDO) lifting thread from N-Finders, designed for minimally invasive facial and body thread lifting procedures. The N-COG is a multiple, bidirectional barbed (multi-cogged) PDO thread that distributes tension evenly along the tissue, helping to lift and reposition sagging skin while stimulating collagen formation. The special cog design is intended to reduce common complications of older thread designs such as skin dimpling, thread protrusion and breakage within the tissue. Each sterile, single-use device consists of an absorbable PDO cog thread mounted on a 21G needle with an effective working length of 100 mm. The threads are CE-marked medical devices and are completely biodegradable by hydrolysis over time.
Bnefits
- Multiple, bidirectional cog design provides strong tissue grasp and lifting capacity along the length of the thread.
- Special cog geometry helps prevent skin dimpling, surface irregularities and thread protrusion compared with traditional barbed threads.
- CE-marked absorbable PDO material gradually hydrolyses in the tissue, reducing the need for removal and supporting safety.
- Insertion via a fine 21G needle allows a minimally invasive procedure with no surgical incision and generally minimal downtime when performed correctly.
- PDO threads can stimulate neocollagenesis and fibrous tissue support, helping to improve skin firmness and contour over time.
- Suitable for lifting and repositioning of soft tissues in areas such as cheeks, jawline and midface when used by trained professionals.
- Supplied as a ready-to-use sterile pack of 6 threads for efficient use in aesthetic practice.
Indications
- Minimally invasive lifting and repositioning of mild to moderate soft tissue laxity of the face (e.g. cheeks, jowls, jawline, midface) when PDO thread lifting is appropriate.
- Adjunctive use in non-surgical facial rejuvenation protocols to improve skin support and contour in suitable patients.
- Use by appropriately trained medical practitioners in aesthetic medicine for PDO thread lifting techniques as permitted by local regulations.
- May be combined with other PDO thread types (e.g. press-cog or scaffold threads) as part of advanced protocols designed by experienced clinicians.
Composition
- Thread material: Polydioxanone (PDO), an absorbable synthetic monofilament suture material.
- Thread type: Multiple, bidirectional cogged (barbed) PDO thread for tissue anchoring and lifting.
- Needle: 21G steel needle (length nominally 100 mm for this variant).
- Each unit is supplied sterile and intended for single use only; no pharmaceutical agent or filler is contained within the thread.
Formulation
- Absorbable PDO cog thread mounted on a 21G needle with a working length of approximately 100 mm.
- Multiple bidirectional cogs arranged along the thread to provide multidirectional tissue engagement.
- Completely biodegradable by hydrolysis in vivo over several months, leaving behind collagenous support tissue.
- Supplied sterile, non-pyrogenic, single-use medical device for subcutaneous/supra-SMAS thread lifting procedures performed by trained professionals.
- CE-marked PDO thread system from N-Finders' N-COG range.
Packaging
- Box/pack containing 6 individually blister-packed sterile N-COG Multi Cogged PDO threads (21G/100mm).
- Each thread and needle set is supplied in a sterile blister with peelable backing for aseptic presentation.
- Outer carton includes product identification, gauge and length, batch/lot number, sterilisation method and expiry date, along with CE mark and manufacturer details.
Usage
- For professional use only; N-COG threads must be inserted exclusively by appropriately trained and licensed medical practitioners familiar with PDO thread lifting techniques and local regulatory requirements.
- Before use, confirm patient suitability, obtain informed consent and follow standard medical history, examination and photography documentation protocols.
- Inspect the sterile packaging; do not use if the blister or outer pack is damaged or if the product is past the labelled expiry date.
- Prepare and mark treatment vectors according to the chosen lifting technique, taking into account anatomical structures, skin thickness and degree of laxity.
- Perform skin antisepsis and maintain strict aseptic technique throughout the procedure.
- Insert the 21G needle carrying the multi cogged PDO thread along the planned subcutaneous or supra-SMAS plane according to accepted thread-lift methodology, avoiding major vessels and nerves.
- After reaching the planned end-point, withdraw the needle while leaving the PDO thread in place, allowing the cogs to engage and lift the tissue along the vector.
- Adjust tension and symmetry as required, then trim any externalised thread ends according to the protocol.
- Apply appropriate post-procedure care (e.g. cooling, topical antiseptic as indicated) and provide the patient with post-care instructions, including activity restrictions and signs/symptoms that warrant review.
- Dispose of all needles, packaging and used materials as clinical sharps and biohazard waste in accordance with local legislation.
- Do not re-sterilise or reuse; the device is strictly single-use.
Contraindications
- Known hypersensitivity or allergy to polydioxanone (PDO) or any material in the device.
- Active local or systemic infection, inflammation or skin disease at or near the intended treatment sites.
- Severe coagulation disorders, current use of significant anticoagulant therapy (unless carefully evaluated and managed by a physician) or history of abnormal scarring or keloid formation.
- Autoimmune connective tissue diseases or uncontrolled systemic disease where wound healing may be impaired, unless the treating physician judges the procedure appropriate.
- Pregnancy and breastfeeding (generally avoided as an elective aesthetic procedure).
- Unrealistic expectations, poor general health or any contraindication identified by the treating medical professional during clinical assessment.
Adverse Effects
- Common, usually transient reactions such as redness, swelling, bruising, tenderness or mild pain at insertion sites.
- Temporary asymmetry, palpable threads or mild surface irregularities as tissues settle after the procedure.
- Skin dimpling, contour irregularities or visible/palpable thread segments if threads are placed too superficially or under excessive tension.
- Infection, abscess formation or delayed inflammatory reactions, which may require medical treatment and in some cases thread removal.
- Thread breakage or migration, potentially necessitating corrective procedures.
- Haematoma, nerve irritation, vascular injury or other complications associated with needle-based aesthetic procedures.
- Allergic or hypersensitivity reactions to PDO or other device materials (rare).
- Any serious or unexpected adverse events should be managed according to standard medical guidelines and reported through appropriate device vigilance systems.
Storage Conditions
- Store in a clean, dry environment at room temperature, away from direct sunlight and sources of excessive heat or moisture, within the temperature range specified on the packaging.
- Keep in original packaging until use to maintain sterility and protect from mechanical damage.
- Do not use after the expiry date printed on the blister or outer carton.
- Do not use if the sterile barrier system (blister or seal) is damaged or opened prior to use.
Duration
The insertion procedure itself typically takes minutes per treatment area when performed by an experienced practitioner, but the lifting and collagen-stimulating effects can persist for many months. PDO threads usually hydrolyse and are absorbed over approximately 6\u201312 months, while the induced collagen framework may support aesthetic benefits beyond this period, subject to patient factors and technique.
Onset
A mechanical lifting effect is often visible immediately after the procedure once swelling subsides, with further improvement over subsequent weeks to months as collagen remodelling and tissue support develop around the PDO threads.
