Abstract: The present disclosure relates to a valve assembly for controlling fluid flow in a channel, which extends along a longitudinal proximodistal central axis (CA). The valve assembly comprises a switch, a deformable tube enclosing the channel, and a sphere arranged within the tube between a distal channel portion and a proximal channel portion of the channel. When the tube is in a non-deformed resting state, the valve assembly is in a closed state, and the sphere is in direct contact with said tube, forming a fluid seal with the tube, and when a force is applied to the switch the tube is in a deformed non-resting state and the valve assembly is in an open state, whereby fluids are allowed pass the sphere. The present disclosure further relates to a biopsy syringe comprising the valve assembly.
