ABSTRACT:
A thrombectomy device includes a tubular shunt generally connected at an upstream end to a relatively high-pressure blood vessel such as an artery and at a downstream end to a relatively low-pressure blood vessel such as a vein. During use, the shunt is disposed mostly outside of the patient. A filter is disposed in the shunt for blocking the passage of clot particles. This device enables a real-time return of blood to the vascular system of the patient. A selectively operable syringe is operatively connected to the tubular member for exerting an auxiliary force on clot material stuck in one of the tubular member and the inlet port element. A three-way valve element is operable in first configuration to couple the suction device to the inlet port element, in a second configuration to couple the suction device to the outlet port element, and in a third configuration to couple the inlet port element and the outlet port element to one another.
