Hydraulic Ankle Products

AvalonK2

AvalonK2 is a hydraulic ankle that has been designed specifically for the complex needs of limited community ambulators. Through a combination of award-winning hydraulic ankle technology and a unique optimised keel, Blatchford has created a prosthesis that works with the user to enhance confidence, independence and safety.

Enhancing walking confidence by hydraulically adjusting to inclines and self-aligning to secure the knee joint, AvalonK2 encourages good posture and joint position. This improves stability, helping to prevent falls and increases balanced limb loading to provide the best performance for limited community ambulators.

Echelon

The award-winning Echelon is a waterproof hydraulic ankle that absorbs and damps on impact, self-aligns on rough and sloping surfaces, then remains dorsiflexed at toe-off. These design features help reduce abnormal pressures at the socket interface and other joints, promote comfort and postural symmetry to help reduce the risk of falls and preserve musculoskeletal health.

EchelonVAC

Optimal socket connection is critical to an amputee’s comfort, security and stability. By pairing Biomimetic Hydraulic Technology with an elevated vacuum system, the design of EchelonVAC works to create a secure and comfortable socket connection.

By harnessing natural ankle motion, EchelonVAC quietly creates elevated vacuum, helping to maintain an optimally fitting socket throughout the day.

Elan

Elan mimics natural muscle resistance and ankle motion by adapting hydraulic resistance levels to optimise stability when standing and walking, on slopes and uneven terrain. This encourages more symmetrical limb loading, faster walking speed and reduced compensatory movements. The ankle pivot point is optimally positioned close to the natural weight line for a more natural response through the gait cycle.

The result is smoother, safer and more natural walking, helping to preserve the body for the long term.

EchelonVT

EchelonVT combines the advanced hydraulic technology of Echelon with an additional rotation and vertical shock absorption element, to reduce the shear forces at the socket interface. This reduces the rate of loading at the socket interface and allows the socket to rotate with the residual limb, rather than against it. This means the user is able to move and adapt more freely, making EchelonVT ideal for taking part in activities such as golf and hiking.
