Intended Use

The CO2 Laser is intended for the ablation, vaporization, incision, excision, or cutting of soft tissue in oral surgery, E.N.T., gynecology, and dermatology. Meditec Laser Technologies proposes that the M.L.T. 30 CO2 laser be limited to prescription use.

Device Story

MLT 30 CO2 laser emits coherent light at 10.6 microns for soft tissue surgery. Operated by surgeons in clinical settings; used for ablation, vaporization, incision, excision, or cutting. Device provides precise tissue interaction; clinical benefit includes surgical removal of lesions or tissue remodeling. Prescription use only.

Clinical Evidence

Bench testing only; no clinical data provided. Substantial equivalence established via comparison of specifications and indications for use to the predicate device.

Technological Characteristics

CO2 laser surgical instrument; emits coherent light at 10.6 microns. Operates in continuous or scanning modes for soft tissue interaction. Prescription use device.

Indications for Use

Indicated for soft tissue ablation, vaporization, incision, excision, or cutting in oral surgery, dermatology (e.g., skin tumors, pigmented lesions, skin tags, resurfacing, blepharoplasty), E.N.T. (e.g., larynx/pharynx tumor surgery, LAUP, stenosis), and gynecology. Contraindicated for patients whose problems are caused by being overweight or drinking problems (E.N.T. context).

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.
