Intended Use

The Dornier Medilas H Laser is intended to be used in cutting, vaporization, ablation, and coagulation of soft tissue in coniunction with endoscopic equipment (including laparoscopes, hysteroscopes, bronchoscopes, gastroscopes, cystoscopes, and colonoscopes), or in incision/excision, vaporization, ablation and coagulation of soft tissue in contact or non-contact open surgery (with or without hand piece). The Dornier Medilas H Laser is indicated for use in medicine and surgery, in the following specialties: Urology, Pulmonology, Arthroscopy, Lithotripsy, Gastroenterology, Gynecology, ENT, and General Surgery.

Device Story

Pulsed Holmium:YAG laser (2080 nm) for soft tissue surgery; utilizes bare quartz glass fibers (400/600 µm) for contact cutting and non-contact coagulation/vaporization. Operated by physicians in clinical/surgical settings. System features microprocessor-controlled operation, photoelectric power meters, and automatic calibration. Safety mechanisms include dual parallel microprocessors monitoring a rotating magnetic shutter; system halts laser production upon fault detection. Output parameters, time functions, and status displayed on graphic panel. Benefits include precise, temperature-controlled tissue interaction. Modified version incorporates new housing and updated 635 nm aiming beam (vs 630 nm predicate).

Clinical Evidence

No clinical data. Compliance demonstrated via bench testing and adherence to performance standards for Class IV light-emitting products (21 C.F.R. § 1040.10, §1040.11) and voluntary standards (IEC-601, IEC 825/VDE 0837/2.86).

Technological Characteristics

Pulsed Ho:YAG laser, 2080 nm wavelength. Quartz glass fibers (400/600 µm). Air-cooled, internal closed-circuit water cooling. Microprocessor-controlled with dual-processor safety monitoring. 635 nm aiming beam. Class IV laser. Complies with IEC-601 and IEC 825.

Indications for Use

Indicated for soft tissue cutting, vaporization, ablation, and coagulation in patients requiring endoscopic or open surgery across urology, pulmonology, arthroscopy, lithotripsy, gastroenterology, gynecology, ENT, and general surgery specialties.

Regulatory Classification

Identification

## Intended Use

The Dornier Medilas H Laser is intended to be used in cutting, vaporization, ablation, and coagulation of soft tissue in coniunction with endoscopic equipment (including laparoscopes, hysteroscopes, bronchoscopes, gastroscopes, cystoscopes, and colonoscopes), or in incision/excision, vaporization, ablation and coagulation of soft tissue in contact or non-contact open surgery (with or without hand piece).

The Dornier Medilas H Laser is indicated for use in medicine and surgery, in the following specialties: Urology, Pulmonology, Arthroscopy, Lithotripsy, Gastroenterology, Gynecology, ENT, and General Surgery.

Technological Characteristics and Substantial Equivalence

The Dornier Medilas H Pulsed Holmium YAG Laser is a compact pulsed HO: YAG laser emitting laser radiation in the invisible range of 2080 nm. The Medilas H provides a temperature-controlled method for contact cutting and non-contact coagulation and vaporization with a bare fiber.

The modified Medilas H has the same principles of operation and similar technological characteristics as the previously unmodified Medilas H (K981718).

The modified Medilas H and the unmodified Medilas H laser systems have photoelectric power meters and are automatically calibrated. They also have a 2-stage waterproof and explosion proof footswitch and both lasers incorporate a watchdog-monitored microprocessor.

Both Lasers depict a graphic display panel which show the laser operating parameters, application modes, time functions, system status and messages for the user.

The Medilas H lasers provide a temperature controlled method for contact cutting and non-contact coagulation and vaporization with fibers made of quartz glass with a bare fiber tip. These fibers are available in diameters of 400 and 600 µm.

The Medilas H lasers feature one mode of operation: Standard. The microprocessor controlled Dornier Medilas H lasers have been developed in accordance with the latest technical standards.

The lasers have a cooling system that includes an air-cooled, temperature controlled, internal closed circuit water system. The cooling systems are identical as concurred in 510(k) # K981718.

As a safety feature, both Medilas H lasers have a single rotating magnetic shutter which moves the filter out of the laser beam. One microprocessor controls the shutter. The Medilas H lasers contain a single shutter with two parallel running microprocessors. Whenever one microprocessor runs differently from the other, the Medilas H laser

{2}------------------------------------------------

hardware initiates a "system fault" routine. During any "system fault" laser production and release immediately halt.

There are minor differences between the Medilas H laser, and the unmodified cleared Medilas H laser (K981718). The modified laser system aiming beam is 635 nm, maximum power at aperture 1mW and the unmodified cleared Medilas H laser aiming beam is 630 nm, maximum power at aperture 1mW. The modified Medilas H is contained in new housing. The dimensional specification is visually different from the predicate (unmodified Medilas H) laser system. These modifications do not present any new issues of safety or effectiveness of the device.

## Performance Data

While no performance standard have been established for HO: YAG lasers under Section 514 of the Federal Food, Drug and Cosmetic Act, the Dornier Medilas H laser is in compliance with class IV performance standards for light emitting products promulgated under the Radiation Control Health and Safety Act of 1968. See 21 C.F.R. § 1040.10 and §1040.11. The laser also complies with the applicable requirements of the following voluntary standards: IEC-601, IEC 825/VDE 0837/2.86.

## Advisory:

This information was prepared for the sole purpose of compliance with the Safe Medical Devices Act of 1990. It does not imply that the procedures described herein can be performed with the equipment described without substantial risk of personal injury or death to patients due to operator error or in procedures requiring a high degree of skill.
