Below Knee Prosthetics
E-pulse (Otto Bock)
Harmony e-pulse opens up vacuum suspension to a wider range of amputees.
This electronic pump delivers clinically proven* benefits of vacuum suspension in a reliable, low profile that amputees will love!
You can fit the e-pulse on a wider range of amputees because it requires:
- No weight limits
- No restrictions on the patient's activity level
- No restrictions on residual limb length
With improved fit, patients enjoy better proprioception, which gives them greater confidence in their prosthesis and contributes to improved mobility.
Vacuum suspension also helps stabilize limb volume. With stable limb volume, amputees can quit adding socks and spots throughout the day and simply enjoy great fit! There will also be less shear forces on amputee's limb that result from an ill-fitting socket. The result is an incredible fit!
