Description
DEFINISSE FREE FLOATING THREADS -12 cm RELIFE/ 6 by RELIFE (Menarini Group) are sterile, resorbable, monofilament barbed suspension threads made of poly(L-lactide-co-ε-caprolactone) [P(LA-CL)]. These free floating threads are bidirectional and converging, with a notched (barbed) length of 12 cm, and are supplied in individual sterile pouches. Designed for REPOSITIONING FOR REJUVENATION, they are indicated for soft tissue repositioning and facial contour enhancement. As part of the DEFINISSE thread range, these threads provide minimally invasive lifting and revitalising effects by engaging soft tissues with their patented barbs, helping to lift and hold sagging tissues to refresh facial appearance and define contours. They are Class III synthetic surgical medical devices, CE-marked, and intended exclusively for professional use by physicians trained in facial thread techniques.

Usage
For professional use only in a medical setting by physicians (e.g., dermatologists, plastic surgeons, aesthetic medicine specialists) who have completed specific training in DEFINISSE thread techniques and facial anatomy.
Before use, read the full Instructions for Use (IFU) and verify package integrity, sterility and expiry date; do not use if the sterile barrier is compromised.
Perform a complete patient assessment, including medical history, medications, contraindications, aesthetic goals and suitability for thread lifting.
Obtain informed consent detailing benefits, risks, alternatives and post-procedure expectations.
Cleanse and disinfect the treatment area thoroughly using appropriate antiseptic measures, and mark insertion points and trajectories according to the planned soft tissue repositioning vectors.
Open the sterile sachet in an aseptic field and handle the thread using sterile gloves and instruments only.
Introduce the free floating thread according to the technique described in the IFU (e.g., using an introducer needle or cannula system, depending on the specific configuration) to position the barbed segment within the soft tissue along predetermined vectors.
Ensure that the bidirectional barbs are correctly oriented and engaged in the tissue so that soft tissues are held and repositioned in the desired direction.
After placement, gently adjust tension and mould tissues externally as needed to refine contour and symmetry, following IFU guidance and clinical judgement.
Provide the patient with written post-procedure instructions, including recommendations to avoid strenuous facial movements, massages, dental procedures, excessive heat/cold exposure and sleeping positions that may compromise threads for a specified period.
Schedule follow-up appointments for assessment, management of potential adverse effects and evaluation of treatment outcomes.
Use threads strictly once; discard any unused or partially used threads in accordance with local regulations for medical sharps and biohazard waste.
Contraindications
Known hypersensitivity or allergy to poly(L-lactide-co-ε-caprolactone) [P(LA-CL)], polylactic acid, ε-caprolactone or any component of the device.
Presence of active infection, inflammation or dermatologic disease (e.g., acne, dermatitis, rosacea flare, herpes) at or near the intended treatment site.
Systemic infection or significant systemic illness at the time of the planned procedure.
Severe coagulation disorders, uncontrolled bleeding diathesis or anticoagulant / antiplatelet therapy where the risk of bleeding or bruising is considered unacceptable by the treating physician.
History of keloid or hypertrophic scarring in areas planned for thread insertion, when the risk is deemed significant.
Autoimmune or connective tissue disorders or other systemic conditions that significantly impair wound healing, unless a specialist determines use is appropriate.
Pregnancy and breastfeeding, due to insufficient safety data for these populations in aesthetic thread-lift procedures.
Patients with unrealistic expectations, body dysmorphic disorder or other psychological conditions that would make them unsuitable candidates for aesthetic procedures.
Any general contraindication to minimally invasive aesthetic interventions as determined by the treating physician.
Adverse Effects
Common local reactions such as pain, tenderness, erythema, swelling and bruising at insertion points and along the thread trajectory.
Localised haematoma or ecchymosis due to blood vessel injury during insertion.
Temporary irregularities, dimpling or puckering of the skin, particularly in early post-treatment stages.
Palpable or visible threads, especially in patients with thin skin or superficial placement; may require massage, adjustment or, rarely, removal.
Infection along the thread path or at entry/exit points, which may require antibiotics and, in some cases, thread removal.
Foreign-body or inflammatory reactions, including nodules or granuloma-like formations, requiring medical evaluation and possible treatment.
Thread migration, partial extrusion, or breakage necessitating corrective measures or removal.
Neurovascular injury, such as temporary or persistent sensory changes or vascular compromise, if critical structures are inadvertently affected.
Scarring or persistent changes in skin texture at insertion sites or along the thread course.
As with all invasive aesthetic procedures, rare but serious complications can occur and must be managed promptly by experienced clinicians.
Storage Conditions
Store in the original unopened packaging in a clean, dry environment at controlled room temperature as specified on the carton.
Protect from direct sunlight, excessive heat, humidity and freezing temperatures to maintain device integrity.
Do not use if the sterile packaging is opened, damaged or otherwise compromised.
Do not resterilise or reuse; product is sterile and intended for single use only.
Keep out of reach of unauthorised persons and in line with local regulations for storage of Class III medical devices.
Duration
Provides an immediate repositioning effect after placement, with clinical outcomes generally lasting many months while the P(LA-CL) threads remain structurally intact. Over time, the threads are resorbed and replaced by fibrous tissue, with duration of effect dependent on patient factors, treatment area, technique and lifestyle.
Onset
Immediate visible repositioning and lifting of soft tissues following correct placement and tensioning of the threads, with further refinement over the subsequent weeks as tissue adapts and fibrous support develops.
