— Device used to maintain a constant volume within an isolated treatment zone while exchanging its internal volume. Current aspiration and lytic delivery thrombectomy devices do not have isolated treatment zone. Suction could result in collapse or the lysis could result in the distension of the vein wall. Device allows for tandem infusion and suction of fluids from this treatment zone while ensuring that the volume within this treatment zone remains constant.
