#0030: Disposable Two-Way Valve Filter for Use in Re-infusion After Blood Clot Removal

FEATURES
Several of the current treatments for thrombotic conditions such as arterial emboli and thrombosis, deep vein thrombosis and pulmonary thromboembolytic disease, require mechanical fragmentation of clots followed by aspiration of clot fragments. During removal, moderate to large amounts of blood can be aspirated along with clot fragments. Keeping blood loss to a minimum is important in any procedure, but it is particularly important in this setting because of the frequently associated concurrent illness and because blood loss could be a factor limiting the success of the procedure unless the blood can be returned in some way.
An Indiana University researcher developed a filter device which allows for the filtration of clot fragments while returning the blood aspirated during the procedure back to the patient. This improves the safety of the procedure for both the patient and the health care worker by minimizing blood handling. The device is elegant in construction, economical, and easy to assemble and use.
The device consists of two reservoirs separated by a one-way valve with a fluid port at one end and a suction port at the other. Blood and clot fragments enter the fluid port and pass through the one way valve into a reservoir above. Suction is removed and the valve closes, allowing blood to pass back through while clot fragments are retained by a semipermeable membrane.
