Harmony Vacuum System

Are you a below-the-knee amputee who struggles with an increase or decrease in limb volume throughout the day?  The Harmony Vacuum System, developed by Otto Bock HealthCare, is a vacuum prosthesis designed to improve the fit and function of lower limb prosthetics. 

Key Features

  1.  Active Vacuum Pump: Continuously maintains negative pressure within the prosthetic socket, available in mechanical or electronic models.
  2. Improved Suspension: Provides a secure and stable fit, reducing limb movement within the socket.
  3. Pressure Distribution: Evenly distributes pressure across the residual limb, enhancing comfort.
  4. Prosthetic Socket: Designed to work with the vacuum pump and suspension sleeve to create an airtight seal.
  5. Liner: Silicone or gel liner cushions the residual limb and helps maintain the vacuum seal.

Possible Benefits

  1. Enhanced Comfort: Reduces limb movement and evenly distributes pressure for improved comfort.
  2. Better Proprioception: Secure fit improves balance and control.
  3. Reduced Skin Issues: Prevents skin irritation and breakdown.
  4. Increased Activity Levels: Supports higher levels of physical activity with greater confidence.
  5. Customization: Adjustable vacuum pressure and socket design tailored to individual needs.


For active individuals, the Harmony Vacuum System is suitable for various activities, including walking and running, and is commonly used for both below-knee (transtibial) and above-knee (transfemoral) amputations.
