Abstract:
1. A method of removing thrombi, the method comprising the steps of: providing a thrombectomy apparatus comprising an elongate shaft defining a high pressure lumen and a low pressure lumen, the high pressure lumen terminating near a distal end of the low pressure lumen, and an expandable capture basket disposed generally adjacent the distal end of the low pressure lumen; wherein the expandable capture basket includes an actuatable frame and a blood permeable membrane disposed over at least a portion of the frame; advancing the thrombectomy apparatus to a desired location within a patient's vasculature; expanding the expandable capture basket; capturing thrombi within the expandable capture basket; providing a source of pressurized fluid in fluid communication with the high pressure lumen; breaking apart the captured thrombi using the pressurized fluid; and providing suction to the low pressure lumen to evacuate the broken apart thrombi.
