The ST&G Eclipse Pump (EP) is a removable elevated vacuum system, incorporating a fabricated space in the distal end of the socket where the pump functions similar to a distal end pad. The EP is engineered out of a medical grade silicone polymer with two valves to control the airflow. As part of a liner and sealing sleeve system, the pump is activated to push out air from the user’s weight during initial contact, and then draws in interior air to provide elevated vacuum after toe off during swing phase. The EP is available with 2 different vacuum levels to accommodate various activity levels and skin conditions.
