Intended Use

The SolarTec™ Source 270 System is intended for use: To provide visible light for with various rigid or flexible endoscopes, other lighted tools, and surgical headlamps that contain fiber bundles or single fibers for illumination In providing illumination for the purposes of allowing observation and manipulation of body cavities and tissues, hollow organs, and canals. With applications that include, but are not limited to, headlights and/or externally illuminated endoscopes used in arthroscopy, bronchoscopy, gynecology, laparoscopy, obstetrics, oto-rhyno-laryngoscopy, urology, and vascular endoscopy as well as surgical headlights used in various open surgical procedures.

Device Story

SolarTec™ Source 270 is a high-intensity metal halide arc lamp illuminator; provides visible light to rigid/flexible endoscopes, surgical headlamps, and lighted tools via fiberoptic cables. Device operates in clinical settings (OR, clinics); used by physicians/surgeons. Input is electrical power; output is uniform white light. Safety features include: lamp replacement door interlock; forced air cooling; internal thermal protection to shut off power if overheating occurs; analog circuitry limiting lamp life to 1000 hours (below 4000-hour rating); internal baffles to dampen sound and confine debris in case of non-passive lamp failure. Uniform light output benefits surgical visualization compared to traditional fiber bundles that attenuate blue light. Device is intended for prescription use.

Clinical Evidence

No clinical data provided. Safety and effectiveness are supported by bench testing and compliance with international electrical safety standards (IEC601-1, IEC601-2-18, UL2601-1).

Technological Characteristics

Metal halide arc lamp light source; forced air cooling; analog circuitry for lamp life management (1000-hour limit); internal baffles for sound/debris containment. Safety interlocks on lamp door. Complies with IEC601-1 (1993), IEC601-2-18 (1996), and UL2601-1. Standalone unit.

Indications for Use

Indicated for providing illumination for observation and manipulation of body cavities, tissues, hollow organs, and canals during endoscopic procedures (arthroscopy, bronchoscopy, gynecology, laparoscopy, obstetrics, oto-rhyno-laryngoscopy, urology, vascular endoscopy) and open surgical procedures using surgical headlamps.

## (510(k) SUMMARY OF SAFETY AND EFFECTIVENESS)

Safety

The Subject Device is designed with a safety interlock on the lamp replacement door. If the cover is opened, the power to the device will be interrupted.

The Subject Device is cooled with a forced air fan to prevent the temperature of the unit from exceeding a safe level. If in the event that the fan malfunctions and/or fails to operate properly and the internal temperature of the device exceeds the engineered specifications, the device is designed with an internal thermal protection mechanism that automatically shuts off the power to the lamp.

The lamp and power source may fail passively (i.e., just not turn on, or just go out). Typically, lamp and power source defects do not result in lamps going out during a surgical case. It is more likely that a lamp cannot be turned on during preparation for a surgical case. The consequences to the user is an inconvenience and a time delay. However, it is expected to result in no adverse medical condition in the patient.

To minimize such inconveniences, the Subject Device contains a user replaceable lamp fixture. Cogent Light encourages the operators to have a spare lamp available on site.

The lamp may fail in a non-passive mode, resulting in an audible sound. This sound may startle the user. Due to the inherent nature of all high intensity lamps. including those found in the Predicate Devices, it is impossible to guarantee against all such failures, although they are rare. To minimize such events, the Subject Device has incorporated several safety features into the product design. These safety features include:

- a) The lamp is never operated beyond its specified power range,
- b) The lamp life is limited to approximately 1000 hours by analog circuitry. This limit is significantly below the safe rated life expectancy of the lamp (approximately 4000 hours) as stated by the lamp manufacturer,
- c) The enclosure has interlor structures (baffles), which will dampen the sound level and confine any debris which might result from the non-passive lamp failure.

The Subject Device will meet the following product safety standards:

- a) IEC601-1-2.1993 (Class B) Medical electrical equipment Part 1: General requirements for safety

2. Collateral Standard: Electromagnetic compatibility - Requirements and tests.

- b) IEC601-2-18:1996 Medical electrical equipment Part 2: Particular requirements for the safety of endoscopic equipment
- c) UL2601-1 2nd ed. Standard for Safety Part 1: General Requirements for safety.

## Effectiveness

Metal halide arc lamps produce light that is spectrally similar to sunlight. The color of the light that is actually delivered to an endoscope, surgical headlight, or surgical instrument, is determined by optical coatings and the transmissive properties of the light delivery system.

The Subject Device used with a Cogent Light single fiberoptic cable typically produces a uniform output image. The output image is independent of the intensity of the light source. By contrast, other commercial fiber bundles and illuminators produce non-uniform images due to the construction of the bundles and optics in the illuminators. Any application involving direct illumination (e.g. surgical headlamp) uniform illumination is a plus.

Fiber bundles have been the standard for light delivery. Due to the transmissive properties of their materials, they will attenuate more in the blue than red region of the spectrum, producing a more yellow light. Cogent Light single fiberoptic cables, used as part of the Subject Device, transmits white light uniformly throughout the visible spectrum,
