1. An implantable tube valve for implanting in a human vessel, the tube valve comprising:
a tube, having an inner tube wall and an outer tube wall that extend between two axial tube ends;
a valve member, connected to a pivot shaft supported by the tube, wherein the valve member is pivotable between an open position and a closed position;
an actuator mechanism that is mounted on the outer tube wall;
a pivot member that is arranged for driving the pivot shaft from the outer tube wall by an actuation force from the actuator mechanism; and
at least one biasing element that is connected to the pivot member and arranged for preloading the pivot member to bistably bias the valve member towards the open position or the closed position;
wherein the pivot member is substantially curved, having a curvature following a contour of the inner tube wall to limit a lateral extension of the implantable tube valve.
