It emits radiant energy at a 2.94 µm wavelength with a 300 µs pulse duration and a 3 mm beam diameter. The device is used to ablate the stratum corneum of the skin, which enhances the absorption of topically applied 4% lidocaine cream to produce rapid local dermal anesthesia. It is intended for clinical use. The healthcare provider uses the device to prepare the skin site prior to procedures requiring local anesthesia, potentially benefiting the patient by providing a rapid anesthetic effect. ## Clinical Evidence Clinical study conducted under IDE at two centers with 320 subjects. Primary endpoint was pain reduction during 23G 5/8" needle insertion compared to placebo, using an accepted pain evaluation model. Results demonstrated the device successfully produces rapid dermal anesthetic effect with topical 4% lidocaine. Safety data from 318 subjects observed 48 hours post-treatment showed no adverse events beyond those associated with placebo treatment. ## Technological Characteristics Portable, battery-powered Er:YAG laser; 2.94 µm wavelength; 300 µs pulse duration; 3 mm spot size. Mechanical ablation of stratum corneum. No software or complex algorithm described. ## Regulatory 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. ## Predicate Devices - Phoresor II Model 900 ([K974855](/device/K974855.md)) - LaserLancet LB100 ([K980538](/device/K980538.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

and in dermatology | LAD, model LAD-01 Proprietary Name: #### Predicate Devices 1.3 Currently marketed Phoresor II Model 900 (K974855) and the LaserLancet LB100 (K980538) were selected as the predicate devices for this submission. #### Description of the Device 1.4 The Norwood Abbey Model LAD-01 is a portable, battery powered, single pulse Er: Y AG laser. The radiant energy produced by this laser has a wavelength of 2.94 um, duration of approximately 300 us, and a beam diameter or spot-size of 3 mm at the treatment site. The radiation delivered by the device is sufficient to remove the stratum corneum of skin exposed to the treatment. #### I : રે Indications for Use The LAD device is indicated for the rapid production of local dermal anesthesia using topical OTC lidocaine 4%. ### 1.6 Safety& Effectiveness An IRB, IDE approved study was conducted over two centers and involving 320 subjects. Full needle insertion of a 23G 5/8" needle was used as a standard pain stimulus. After needle insertion subjects were asked to rate the pain felt using an accepted pain ever the model; pain scores were tested to rate the pain felt using an accepted pain evaluation model; pain scores were tested and analyzed as per the approved protocol. Perc Results revealed that the model LAD-01 can produce a rapid dermal anaesthetic effect using topical OTC lidocaine 4%. Analysis of clinical observation c ual observations from 318 subjects treatment revealed no and sisted of clinical observations from 318 subjects taken approximately 48 hours after treatment revealed no adverse events over those of the placebo treatment statyols of chinical observations from 318 subjects taken approximately and {1}------------------------------------------------ Image /page/1/Picture/1 description: The image is a black and white logo for the U.S. Department of Health & Human Services.
