PRODUCT DESCRIPTION

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

INTENDED USE

The Celsus iVT is a prosthetic foot designed to replace one or more functions of the biologic human foot. The device incorporates a vacuum pump to draw air from the socket for the purpose of suspension.

INDICATIONS:

• Lower limb amputations

CONTRAINDICATIONS:

• Make sure that the socket is well fitting before any use; Never use a loose fitting or leaking socket with the Celsus iVT Foot.

PROTECTIVE COVER ON DOME

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

CELSUS IVT OVERVIEW

• During full dorsiflexion the maximum attainable vacuum ranges from 18-22inHg.
• Vacuum suspension is generated when the user applies a load to the toe. The integrated pump draws air from the socket during each step until elevated vacuum is achieved inside the socket.
• The firmness category of the foot can affect the number of steps needed to reach maximum vacuum pressure.
• Liner selection is the sole responsibility of the provider. College Park recommends against the use of Copolymer Gel liners with the Celsus iVT Foot.

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.

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.
ENDOSKELETAL MOUNTING
Use only high quality proximal endoskeletal components.
STATIC ALIGNMENT
For optimal function, balance the patient’s weight evenly between the heel and toe (Figure 4).

• The Celsus iVT was designed with a 3/8” (10.0 mm) heel rise.
• The load line divides the foot at 1/3 heel lever and 2/3 toe lever.

DYNAMIC ADJUSTMENTS

INSTALLING THE CELSUS IVT
College Park recommends the iVT valve kit to connect the system to the socket. Use of other products is the sole responsibility of the provider.
TUBE CONNECTION

1. Attach the tube to the hose connector.
2. Cut the tube to a proper length and connect to the socket.
3. Use the supplied tube retainer to secure the tube to the pylon or other adapter.
4. Position the tube on the medial side to avoid damage.
5. Once assembled verify the pump is working properly; creating vacuum during gait and not leaking air.

TUBE INSPECTION
The tube is the most sensitive part of the Celsus iVT and should be fitted carefully. Verify the tube is NOT:

• Folded or pinched (Figure 2)
• Contacting sharp objects
• Punctured
• Dangling or hanging during gait
• Located laterally, to avoid damage

CHANGING HOSE CONNECTOR SIDE

The hose connector is pre-assembled for a left foot and can be reconfigured for a right foot.

1. Use a 5/16 wrench to loosen the hose connector and exhaust vent.
2. Switch the positions. Ensure the check valves are oriented in the correct direction for proper function (Figure 3).
3.  Retighten. Torque to 35 in-lbs (4 N-m).

PUMP DISASSEMBLY AND REASSEMBLY
(FOR MAINTENANCE)
DISASSEMBLY

1. Disconnect the tube from the hose connector.
2. Use a T9 torx wrench to loosen the housing cap fasteners, remove the fasteners (Figure 5-A).
3. Release the housing cap (Figure 5-B).
4. Use a T9 torx wrench to loosen the air bladder fastener and remove the washer (Figures 5-C & 5-D).
5. Gently pull the air bladder from the housing (Figure 5-E).
6.  Remove the return spring assemblies (Figure 5-F).
   Note: Do not disassemble the pump or foot module further. Additional disassembly with void the warranty.

REASSEMBLY

1. Install new return spring assemblies.
2. Insert a new air bladder into the housing.
3. Replace the washer and air bladder fastener. Torque to 5 in-lbs (0.6 N-m).
4. Replace the housing cap.
5. Thread the fasteners into the housing. Torque to 5 in-lbs (0.6 N-m).
6. Reconnect the tube to the hose connector and use the tube retainer to secure the tube to the pylon or other adapter.

PUMP INSPECTION

Verify the following:

• Make sure that the pump is functioning properly, and the system is not leaking.
• Confirm the CPI sock does not interfere with the Celsus iVT as it could compromise the function of the pump.
• Are the check valves oriented in the correct direction (Figure 3)?
• Is the air bladder fully inserted into the housing?
• Are the inlet and outlet ports tightened?
• Is the tube fully inserted on the inlet port? (Check both at the socket valve and at the bladder housing)

CLEANING

Components may be cleaned with mild soap or isopropyl alcohol and rinsed with water. DO NOT use solvents stronger than isopropyl alcohol as it might degrade the material or get through the valve and into the socket.
WARNING

• Make sure that the socket is a close fit to prevent blistering and/or wounds.
• The tube must be well secured at all times.
• Never operate this product if it is not working properly. Users should report any concerns to their prosthetist immediately, including but not limited to: loose fit, noise, sudden loss of function, etc.
• Contaminants such as dirt and the use of lubricants or powder may affect the function of the prosthesis and lead to a lack of proper function.
• Do not expose this product to corrosive materials, salt water or pH extremes.
• Misuse of this product may result in loss of vacuum, leading to loss of suspension and potential fall.
• Any further disassembly or modification of components will void the warranty.

The following activities will void the warranty:

• Usage with Copolymer Gel liners.
• Usage without liners or other means which can lead to sweat or other fluids entering the system.
• Exposure to environment with extreme airborne particle contamination.
  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.
