The Dynamic Vacuum (DVS) is bridging the gap between valve and Harmony socket technology for transtibial fittings.

Integrating innovative design with simplicity, the Dynamic Vacuum reduces the movement between the limb and socket associated with limb volume fluctuations.

The 6Y94 DVS liner connects magnetically to the 4R220 DVS pump and a knee sleeve is used to seal the system. Vacuum is generated during walking and this elevated vacuum is maintained in both swing and stance phase as opposed to passive systems such as a one way valve that only generate suction during swing phase. This give the user enhanced control and fit during all phases.

6Y94 DVS liner made from TPE (Thermoplastic Elastomer) is thicker anterior and thinner posterior for protection and ease of flexion. Available in 6 sizes – S, M, MP, L, LP, XL
