WillowWood OneSystem AK

The highly innovative OneSystem AK allows transfemoral and knee disarticulated amputees to use an elevated vacuum system. Its unique dual seal guarantees reliable suction suspension (reaching from the distal end all the way to 2.5 cm below the removable brim) during all activities. Simultaneously, the system also shows a very high tolerance for volume changes.
