First, patients access these tubs by means of certain patient transport and lift devices; in certain models, ambulatory patients enter these devices through a door in the side of the tub. Second, once the patient is comfortably position in a seated or reclining in the Silcraft tub or a predicate device's tub, the attendant (or the patient in certain models of the Silcraft Whirlpool System and a couple of the predicate devices) adjusts the valves on the control console to set the volume and temperature of the water flowing into the tub or shower. Third, the attendant (or the patient in certain models of the Silcraft Whirlpool System and a couple of the predicate devices) operates the whirlpool feature of the device by adjusting one or more aeration switches or knobs on the control panel. The attendant (or the patient in certain models of the Silcraft Whirlpool System and a couple of the predicate devices) then manually adjust both the direction of the whirlpool jets by turning them. Fourth, patients exit the Silcraft Whirlpool System's or the predicate devices' tubs by means of the same patient transport and lift devices thev used to enter the tubs or by simply exiting the tub through the tub door in certain models. Fifth, the attendant cleans and disinfects the tub using the devices' built-in disinfection system. #### Technical Characteristics Ten of the eleven models of the Silcraft Whirlpool System and all of the predicate devices consist primarily of the following components: (1) a tub; (2) a shower wand; (3) a control console; (4) a water temperature control; (5) a whirlpool motor; (6) multiple whirlpool jets; and (7) a built-in automatic or manual disinfection system. One models does not have a built-in disinfection system. Each model of the Silcraft Whirlpool System and all of the predicate devices are labeled for use with one or more patient lift and/or transfer devices, including certain Silcraft transporters and lifts ("the Silcraft Patient Lift"). The {2}------------------------------------------------ Silcraft Patient Lift and the legally marketed lifts are intended be used to transport patients from the bed to the bath and vice versa and to lift them into and out of the tub. Any minor technological differences between the Silcraft Patient Lifts, most of which are exempt from 510(k) requirements, and legally marketed lifts do not raise any new questions of safety or effectiveness. The labeling for the models of the Silcraft Whirlpool System that have built-in disinfection systems state that Silcraft Disinfectant should be used to disinfect the devices. This general purpose disinfectant is registered with the Environmental Protection Agency ("EPA"). For this reason, the Silcraft Disinfectant device is substantially equivalent to reference products FDA has on file. ## Summary Basis for the Finding of Substantial Equivalence The safety and effectiveness of the Silcraft Whirlpool System is based on the long history of use of hydrobaths with very similar technological characteristics. The Silcraft Whirlpool System and all of the predicate have the same intended use: bathing and hydromassage. The various models of the Silcraft Whirlpool System also have very similar principles of operation and technological characteristics as the predicate devices. Moreover, the minor technological differences between the Silcraft Whirlpool System and the predicate devices, namely the number of valves on their control consoles, certain components of their disinfection systems and different features of the lifts which they are labeled for use with, do not raise any new questions of safety or effectiveness. Thus, each model of the Silcraft Whirlpool System is substantially equivalent to the predicate devices. All of the Silcraft Patient Lifts are exempt from 510(k) requirements because they are non-AC-powered lifts. Nevertheless, these patient lifts are substantially equivalent to legally marketed lifts with which the predicate devices are labeled for use because they have the same intended use, similar principles of operation and technological characteristics. Any minor differences in their technological characteristics do not raise any new questions of safety or effectiveness. The BA a egistered Silerate Disinfect ant is substantial equivalent, to other general purpose disinfectants hy virtue of its EPA registration and compliance with BPA and Tandum of danderstanding cogarding liquid chamicale germicides and TDA syuidance documents regarding general purpose disinfectants of and-bydrobath 6mm 3 {3}------------------------------------------------ Image /page/3/Picture/2 description: The image shows the logo for the U.S. Department of Health & Human Services.
