PRODUCT DESCRIPTION

This prosthetic foot device is constructed with an integrated pyramid, ankle- housing assembly, two composite springs, and heel wedge. The toe spring is secured to the housing and heel spring with fasteners.

INTENDED USE

The Odyssey K3 is a prosthetic foot designed to replace one or more functions of the biologic human foot.
INDICATIONS:

• Lower limb amputations

ONTRAINDICATIONS:

• None known

PROTECTIVE COVER ON DOME
Remove the protective cover on dome after alignment is completed and before patient leaves clinic.

TECHNICAL SPECIFICATIONS

*26cm foot w/shell
GAIT MATCHING® GUIDELINES
The gait match determines the firmness of the foot based on the user’s specifications (foot size, patient weight, and impact level).

FIRMNESS CATEGORIES

Refer to the chart below to determine the correct firmness category.
Note: Incorrect category selection may result in poor device function. Contact College Park Technical Service if you have questions about category selection.

MOUNTING
Use only high quality endoskeletal components.
ASSEMBLY AND DISASSEMBLY (FOR SOCK REPLACEMENT)
Use the Foot Horn to don and doff the foot shell. Remove the CPI Sock and replace as needed. Any further disassembly or modification of components will void the warranty.
HYDRAULIC RANGE (Figure 2)
The Odyssey K3 foot has 12º of hydraulic motion. The foot is designed to provide 3º hydraulic dorsiflexion from
the neutral standing position.
The foot was developed utilizing a dynamic carbon fiber base. As a result, a typical user will experience an additional range of dynamic motion during ambulation.
Note: Excessive angular adjustment will affect the hydraulic range of the foot. After making an alignment change, ensure that the user retains 3º of hydraulic dorsiflexion.
STATIC ALIGNMENT (Figure 3)
For optimal function, balance the patient’s weight evenly between the heel and toe.

• The Odyssey K3 was designed with a 3/8” (10 mm) heel rise.
• The load line divides the foot at 1/3 heel lever and 2/3 toe lever.

Using a 3mm hex key for adjustment, the hydraulic valves should be set at minimum resistance. Have the user stand comfortably and evaluate the heel-toe balance of the foot.
They will sense the hydraulic movement of the ankle but should not feel like they are falling forward or backward.
Use alignment to position the foot at the point where they feel the most balanced.

DYNAMIC ADJUSTMENTS (Figure 4)
Have the user begin by walking on level ground, to evaluate the heel-toe resistance and gait timing. Using a 3mm hex key, adjust for planterflexion resistance first, then dorsiflexion.
Finalize dynamic alignment by observing the user walking on an inclining- declining surface (ramp). Make further adjustments to the resistance valves as necessary.

• Posterior (Figure 4A)
• Anterior (Figure 4B)

Planterflexion resistance affects the user’s gait from Heel Strike to Foot Flat.
Dorsiflexion resistance affects the user’s gait through Midstance, as the body travels over the foot.

Rounded Heel Wedge
Softer Planterflexion| Turn P-valve counterclockwise (less resistance)| Remove Rounded Heel Wedge
Firmer Dorsiflexion| Turn D-valve clockwise (more resistance)| NONE
Softer Dorsiflexion| Turn D-valve counterclockwise (less resistance)| NONE

ADDITIONAL CONSIDERATIONS

Have the user practice standing up from a seated position in order to acclimate to the motion of the ankle. Use caution when driving. Make sure the user is comfortable with the motion of the ankle if using the Odyssey K3 as their driving foot.
WARNING

• Do not expose this product to corrosive materials, salt water or pH extremes.
• Contaminants such as dirt and the use of lubricants or powder may effect the function of the CPI Sock and lead to noise.
• Failure to follow these technical instructions or use of this product outside the scope of its Limited Warranty may result in injury to the patient or damage to the product.

RESIDUAL RISK STATEMENT
NOTICE OF RESIDUAL RISK
During fitting process, ensure that CPI sock does not become pinched between foot and endoskeletal componentry.
