Below-knee prosthesis with: Triton Harmony
The most intimate fit. Ever. The Triton Harmony elevated vacuum system
The Triton Harmony volume management system
We’ve taken two of our best prosthetic systems—the Triton carbon fibre foot and the Harmony volume management system—and combined them to make one of the best below-knee systems available.
By improving linkage with your leg, the Harmony system improves your gait and increases security, while the Triton foot, with its split toe and shock-absorbing functional ring, handles any lumps and bumps you find along your way.
And to work with other prosthetic feet and even above-knee systems The Harmony system is also available in the form of the P3 mechanical pump (see accessories).
Intimate fit through vacuum
With the Triton Harmony’s vacuum system, you’ll find that your leg is drawn more completely into the socket. You’ll feel the difference, with improved comfort, stability, and ‘connection’—and more natural walking.
Walk your way
The Harmony Triton’s foot is great for all your activities and sports. Its three carbon fiber springs absorb your energy as you land on your heel—then release that energy to give a little push when your toe leaves the ground.
Twist and shout!
And take on any bumps in the road with torsion and shock absorption provided by the Triton Harmony’s functional ring, which also generates the vacuum for the system.
Finally, a silver lining!
We’ve got the right liner for you, with silicone solutions as well as our highly recommended Anatomic 3D PUR (Polyurethane) liner. It distributes pressures in your socket to create a precise and comfortable fit, and adds comfort and increases connection no matter how active you are.
Go wherever life takes you
The Triton Harmony’s split toe design adapts easily to uneven terrain, adding safety and stability when walking or standing.

What you need to know
The Harmony solution
Do you have a problem with your prosthesis? We’ve got the solution!
Is your prosthesis ever uncomfortable? Does your socket seem to get looser over the course of the day? Does your leg feel poorly ‘connected’ to your prosthesis?
These issues can come from volume changes in the socket and—just like a shoe that’s the wrong size—can lead to painful skin problems that limit your activities.
The style of socket can make things worse for some users. Conventional Specific Weight Bearing Sockets can cause fluid loss by forcing fluids out of the limb during walking, while simultaneously reducing the surface area that distributes pressures.
To make up for the changes in limb volume, many users add socks to their residual limb during the day—but this doesn’t get to the root of the problem: the loss of fluid and volume fluctuations.
A Specific Weight Bearing Socket can force fluids out of the limb, changing the limb volume.
The Harmony Triton elevated vacuum system includes a socket, the liner (between your leg and the socket), the Harmony functional ring, and the Triton carbon fibre foot. They all add up to incredible comfort!
Intimate fit begins with the right socket…
Conventional sockets force your leg to conform to the shape of the socket, and can create pressure peaks in sensitive areas. A TSWB (Total Surface Weight Bearing) socket on the other hand, supports your weight with its entire surface, instead of just on the edge or at the bottom.
It’s like the difference between walking in a shoe that fits perfect versus a shoe two sizes too big; even if you add enough socks, it will feel sloppy and may cause blistering.
...and the perfect liner...
Our Anatomic 3D PUR liner (made from PolyURethane) distributes pressures in your socket to create a precise and comforable fit. It adds comfort and increases connection no matter how active you are.
…and adds vacuum for amazing connection and comfort!
Add to the TSWB socket the Harmony’s elevated vacuum, and you’ll find that your leg is drawn more completely into the custom socket. This creates a more intimate fit, and allows fluids to be more easily drawn back into your limb when you’re walking.
You’ll feel the difference immediately:
- Improved comfort and stability
- Enhanced connection, or ‘linkage’ will help you feel where your leg is in space (proprioception),
- Walk more naturally: by allowing you to spend more time on your prosthetic side
- It may even help maintain skin health by increasing fluid flow.
Handle any bumps in the road: torsion and shock absorber
At the heart of the elevated vacuum system is the Harmony functional ring. The ring acts as a pump with intake and exhaust valves to create the elevated vacuum. It also provides shock absorption and can even twist while you’re loading it—just like a real ankle.
These feet were made for walking!
Great for all your activities, the Triton’s three carbon fiber springs work together to give you a seriously smooth rollover. Add to that the adjustable heel, which helps to absorb shocks along with the functional ring—and you can finally walk the way you want to walk.
Go wherever the road takes you.
