## Summary of Safety and Effectiveness
Prismalix™ Surgical Light June 11, 1998
#### INTENDED USE
ALM Prismalix™ (PRX) Surgical Lights are intended to provide visible illumination for the surgical field or for the examination of the patient. PRX is designed to eliminate shadow, reduce reflected heat, and illuminate surgical incisions of all depths during surgical procedures. The ALM Surgical Lights will be used in indications, which are the same as indications for other surgical lights currently offered for commercial distribution in the United States.
### PRODUCT DESCRIPTION
ALM Surgical Equipment, Inc. has been selling Surgical Lights in the United States since July 1988. The products sold were and are manufactured by the parent company of ALM Surgical Equipment Inc., ALM SA, located in France. The Prismalix™ series continues to be manufactured by the parent organization, ALM SA.
The new product known as "Prismalix™" is of similar technology to surgical lights covered under D.C. Number K882613 issued on June 29, 1988. The differences between the new Prismalix™ models and models previously sold are cosmetic along with the addition of a tilting mechanism (in selected models) which allows variations in pattern size.
The surgical light consists of single or multiple lightheads attached to suspension arms supported from hospital installed mounting plates. Light heads can be positioned for optimal illumination of the surgical site by grasping sterilizable handles or non-sterile handles on the lighthead.
Low voltage power is supplied to the light bulb by way of a remote mounted transformer similar to those used by other surgical lighting manufacturers. Light intensity is controlled by a dimmer system, mounted remotely at a wall location.
Illumination is measured in footcandles or lux (1 footcandle equals 10.764 lux). Reference publication RP-29-95 Lighting for Hospitals and Health Care Facilities chapter 4, section 11, page 18. Illuminating Engineering
{1}------------------------------------------------
Society of North America. New York, NY 1995. IES recommends a minimum illumination level at the surgical site of 2,500 footcandles when the light is positioned one meter above the site. The Prismalix™ series meets and exceeds this recommendation.
The previous range of lighting covered under K882613 is referenced by the three sizes of light heads; 500 mm or 5000 series, 700mm or 7000 series, and 900mm or 9000 series. The Prismalix™ series will be referenced by three sizes of light heads; 400mm or 4000 series, 600mm or 6000 series, and 800mm or 8000 series.
It is possible to provide a fixed focus video camera in selected 4000 series light heads. This Prismavision camera is similar in overall design and construction to the current ALM fixed focus camera, and other surgical/endoscopic video cameras offered for commercial distribution in the United States.
Contained in Section II of this submission are brochures that provide photos and specifications of some of the various models offered as part of the PRX series. The design of the PRX series is similar in overall design and construction to the current ALM products; and other surgical lights with variable pattern sizes, offered for commercial distribution in the United States.
### RATIONALE FOR SUBSTANTIAL EQUIVALENCE
The ALM Prismalix™ Surgical Light is substantially equivalent in materials, design, and function to surgical lights currently in commercial distribution in the United States. Specifically, the ALM Prismalix™ Surgical Light is substantially equivalent to the following systems:

{2}------------------------------------------------
- 4. Midmark (Chick Surgical), Versailles, OH 45380 Reviewed by the FDA (K860739), 03/28/86
All of these systems are ceiling, wall or mobile mounted surgical lights intended to provide acceptable levels of illumination to the surgical site.
All of these systems are modular in design to allow for maximum flexibility in meeting the needs of individual users during a variety of procedures.
The following charts provide a comparison of features of the ALM Prismalix™ Surgical Light to other similar commercially marketed systems.

### Safety Features
The ALM Prismalix™ Surgical Light described in this premarket notification was designed to meet criteria for Surgical Lighting as outlined in IEC 601-2-41 and manufactured using component materials accepted by Underwriters Laboratories.
360° rotation of the system's suspension arm and lighthead is made possible through the use of fully rotating electrical contacts, eliminating the possibility of twisting, binding and breaking of any internal wiring.
Each bulb in the lighthead is energized by 4 amps of low voltage power (23 volts).
Both sterile and non-sterile positioning devices are provided to maintain integrity of the sterile environment during surgical procedures.
All rotating joints in the suspension system are equipped with fully adjustable friction brakes to avoid unintentional movement after positioning of the lighthead for a procedure.
ALM has completed appropriate safety testing and has received Notice of Authorization to Apply the UL and C-UL Marks from Underwriters Laboratories, Inc., International Compliance Services on May 29, 1998. A copy of the notification is included in Section IV.
The PRX 4000, 6000, and 8000 series products referenced in this premarket notification are identical to those referenced in the above letter by Underwriters Laboratories, Inc.
### ADVERSE SAFETY AND EFFECTIVENESS INFORMATION
For correct and effective use of the ALM PRX Surgical Light and to avoid potential safety hazards, it is essential to follow the recommendations contained in the manuals provided with the device. Any use of the apparatus requires full understanding of user instructions. The apparatus is only to be used for purposes specified here.
{8}------------------------------------------------
Professional installation is required to ensure that all local standards and codes are met. Failure to meet these standards could result in injury or harm to patients and healthcare personnel.
