Intended Use The Wave Comfort 3 (WC3) prosthetic foot is intended for use in lower extremity prostheses. The foot uses three carbon composite elements (Figure 1) that conform to terrain while storing and releasing energy during gait. The two upper carbon springs in the WC3 combine to provide a high rate of energy return while the separation between those springs reduces stiffness in all three planes.
It is recommended that prosthetic feet be stored in a cool, clean, dry environment away from harsh chemicals (chlorine, acids, acetone, etc.). Warnings and Precautions CAUTION: The Wave Comfort 3 is designed to be maintenance free and should not be disassembled. The pyramid dome on the foot is permanently attached to the pylon (main and top) spring and should not be removed.
Standard bench alignment techniques may be used for the Wave Comfort 3 (Figure 2). Before aligning, the initial heel height should be established. The Wave Comfort 3 is designed for a ⅜ inch or 1 cm heel height. The initial heel height can be established with a simple spacer under the heel.

Dynamic Alignment The Wave Comfort 3 is flexible and conforms well to the ground. This characteristic may make the foot appear to be properly aligned after the static alignment. However, small adjustments in the alignment however will smooth the transition from heel to toe, optimize gait and efficiency.
This stiffness can be dynamically adjusted by changing the amount of plantar/dorsi-flexion of the foot. This adjustment increases or decreases the amount of anterior support during gait. If a smooth stance phase of gait cannot be achieved, contact Fillauer for additional assistance . Consumable Components:...
• If the foot shell is too tight, a smooth-edged shoehorn may be used to disengage the heel lock . Compatibility Fillauer feet are appropriate for use with Fillauer or equal, ISO 10328 compliant, endoskeletal components. A Fillauer foot shell should be used with this device, the fit of other manufacturers’ shells cannot be guaranteed .
applicable laws and regulations for the handling of contaminated material . All metal components may be removed and recycled at the appropriate recycling facility. Warranty • 36 months from date of patient fitting • Foot Shell (sold separately) — 6 months from date of patient fitting. User Instructions The providing health care professional must review the following information directly with the user.
Comfort 3. The life of the foot shell will depend on level of activity and degree to which it is protected from wear and damage with socks and shoes. Socks and shoes should be worn at all times and should be allowed to dry fully after exposure to water to prevent damage to the shell.
