Acute & Chronic Wound Healing Acceleration

On the MULTILINE™ platform, LINLINE accelerates healing of acute surgical wounds and chronic non-healing ulcers using a two-step method: precise Er:YAG ablative sanitation to create a clean, vital wound bed, followed by RecoSMA® field therapy to trigger reparative regeneration—all with minimal collateral trauma and short recovery.

Why this method works

Clean first, then regenerate. Short-pulse Er:YAG (2.94 μm) removes biofilm, fibrin and necrotic tissue layer-by-layer (≤ ~100 μm/pass) under direct visual control, without deep thermal injury (“blood-dew” endpoint confirms that only non-viable tissue was removed). This creates an optimally prepared bed for healing or secondary closure.
Deep, non-thermal stimulation. With the SMA module, RecoSMA® delivers thousands of micro-beams (≤ 50 μm; ~10,000/cm²) that launch acoustic waves into the dermis—up to ~6 mm depth—to disrupt pathological structures and activate reparative regeneration (neovascularization, functional tissue replacement) while preserving the epidermal barrier.
Visible, rapid milestones. After sanitation + RecoSMA®, clinicians commonly observe granulation within 3-5 days and marginal epithelization soon after; pain often decreases within several days.

Indications

Chronic wounds / ulcers: venous, lymphostatic, arterial, neuro-/diabetic, pressure ulcers, and post-traumatic or post-surgical non-healing wounds.
Acute surgical complications: infected, dehisced, or necrotic wounds after procedures (e.g., mastopexy, facelift, abdominoplasty, blepharoplasty).

The method may also prepare the wound for secondary sutures or skin grafting sooner, shortening total healing time.

What a session looks like

Step 1 — Ablative sanitation (Er:YAG)

Goal: remove necrotic tissue, slough, fibrin, biofilm, and reduce microbial load without heating viable layers.
Technique: short microsecond pulses with visual control until “blood-dew” appears; if residue persists, repeat sanitation. Painless or low-pain when parameters respect tissue thermal relaxation.

Step 2 — RecoSMA® therapy

Goal: stimulate reparative regeneration in and around the wound; improve microcirculation; counter fibrosis.
Technique: SMA pass across the wound bed and at least 2-3 cm around the margin; efficacy rises with adequate perilesional coverage.
Dressings: typically a dry sterile bandage; combine with compression/unloading when indicated (e.g., venous ulcers).

Results you can expect

Chronic ulcers (real-world cases): long-standing venous/lymphatic ulcers healed after courses of Er:YAG sanitation + RecoSMA® (e.g., complete epithelization over weeks to months, often without additional topical drugs).
Post-op wound dehiscence/infection: daily sanitation + RecoSMA® prepared for secondary sutures in 3–14 days; full closure typically 17–64 days from start, with or without adjunct VAC therapy.
Aesthetic-surgery wounds: case series report healing in 10–33 days depending on size/severity when combining targeted ablation and RecoSMA®; KTP 540 nm or Nd:YAP/KTP may be added once to normalize microcirculation in select cases.

Course planning

Chronic ulcer (outpatient): start with more frequent visits (e.g., every 2–3 days → weekly as the wound cleans and granulates) until stable epithelization; number of sessions varies by etiology and off-loading/compression compliance.
Post-surgical wounds: sanitation daily early on; RecoSMA® 4–6 sessions total depending on response; consider closure once the bed is clean and granulating.

Safety & practical notes

Er:YAG vs other lasers: choosing 2.94 µm with microsecond pulses enables layered ablation without deep heat—something not achievable with CO₂ or deeper-penetrating IR wavelengths in this indication.
Treat the cause, too. RecoSMA® accelerates local healing, but etiologic factors (ischemia, venous hypertension, diabetes control, pressure/unloading) must be addressed in parallel. Use compression, off-loading, revascularization, antibiotics, or NPWT as standard of care dictates.
Pain management: sanitation is usually well tolerated; RecoSMA® can be felt more deeply—reduce pulse frequency rather than energy for comfort.
Contraindications: uncontrolled systemic infection, untreated ischemia, or inability to comply with compression/off-loading where required. (Clinician judgment prevails.)

Benefits at a glance

For patients

Faster, cleaner healing with less pain and shorter dressing timelines.
Lower risk of collateral damage thanks to non-thermal, layer-controlled sanitation.
Often fewer topical drugs and simpler aftercare once the bed is clean.

For practitioners

Reproducible endpoints: “blood-dew” for sanitation; granulation/epithelization for progress.
Versatile workflow: prepares beds for secondary sutures or grafts; integrates with VAC therapy and compression.
Platform efficiency: runs on MULTILINE™; same RecoSMA® module used across scars and regenerative dermatology.

Key takeaway

By combining micro-controlled Er:YAG sanitation with deep, non-thermal RecoSMA® stimulation, LINLINE provides a structured, platform-based pathway to accelerate healing in acute and chronic wounds—cleaning the bed, jump-starting granulation, and moving patients toward closure faster and more comfortably.
