摘要
A thrombectomy system and method of extraction of thrombus are disclosed. The thrombectomy system comprises a delivery catheter; an aspiration catheter, comprising an aspiration funnel, configured to be movably disposed within the delivery catheter in a retracted position and at least partially outside the delivery catheter in an extended and expanded position, the funnel comprising a non-permeable covering, the funnel being configured to adapt its shape and length to a surrounding blood vessel such that the funnel reduces blood flow through the blood vessel and lengthens as it narrows to retain a thrombus within the funnel; a clot-capture element configured to capture the thrombus and to be at least partially withdrawn with the captured thrombus into the funnel; and a microcatheter adapted to carry the clot-capture element to the thrombus. The clot-capture element is movably disposed within the microcatheter in a retracted position. The microcatheter is movably disposed within the aspiration catheter.
