Intended Use

The Cynergy Multiplex is indicated for treatment of vascular lesions, pigmented lesions, tattoos, wrinkles and hair removal.

Device Story

Cynergy Multiplex Laser is a multi-wavelength surgical laser system featuring both organic dye (585, 590, 595, 600 nm) and Nd:YAG (1064 nm) lasing media. Operated by physicians in clinical settings via footswitch, the device delivers either single-wavelength pulses or a sequential combination of two wavelengths (multiplex mode). The system uses lens-coupled quartz optical fibers and handpieces with variable spot sizes to target melanin or vascular structures. By delivering controlled laser energy, the device induces coagulation, hemostasis, or selective photothermolysis of target tissues. This process facilitates the removal of vascular/pigmented lesions, tattoos, and hair, as well as wrinkle reduction. The multiplex mode allows for sequential pulse delivery with adjustable inter-pulse delays (20-2000 ms) to optimize therapeutic outcomes for vascular conditions.

Clinical Evidence

No clinical data provided. Substantial equivalence is based on technological characteristics and performance specifications.

Technological Characteristics

Multi-wavelength laser system (Pulsed Dye: 585-600 nm; Nd:YAG: 1064 nm). Energy delivery via lens-coupled quartz optical fibers. Spot sizes: 4.8-12.3 mm (PDL), 2.8-15.3 mm (Nd:YAG). Pulse width: 0.5-40 ms (PDL), 0.5-300 ms (Nd:YAG). Repetition rate: 1-2 Hz (PDL), 1-10 Hz (Nd:YAG). Electrical: 110/220 VAC. Multiplex mode allows sequential pulse delivery with 20-2000 ms delay.

Indications for Use

Indicated for benign vascular/vascular-dependent lesions (port wine stains, hemangiomas, warts, telangiectasia, rosacea, venous lakes, leg veins, spider veins, poikiloderma of Civatte), benign cutaneous lesions (lentigos, solar lentigos, café au lait macules, seborrheic keratoses, nevi, chloasma, verruca, skin tags, keratoses), tattoos (black/blue-black), wrinkles (periocular/perioral), unwanted hair reduction, and pseudofolliculitis barbae (PFB). Multiplex mode is indicated only for benign vascular and vascular-dependent lesions.

Regulatory Classification

Identification

(1) A carbon dioxide laser for use in general surgery and in dermatology is a laser device intended to cut, destroy, or remove tissue by light energy emitted by carbon dioxide.(2) An argon laser for use in dermatology is a laser device intended to destroy or coagulate tissue by light energy emitted by argon.
