Systems and methods for removal of thrombus from a blood vessel in a body of a patient are disclosed herein. The method can include the steps: providing a thrombus extraction device including a proximal self-expanding member formed of a unitary fenestrated structure, a distal substantially cylindrical portion formed of a net-like filament mesh structure, and an inner shaft member connected to a distal end of the net-like filament mesh structure; advancing a catheter constraining the thrombus extraction device through a vascular thrombus, deploying the thrombus extraction; retracting the thrombus extraction device to separate a portion of the thrombus from the vessel wall and to capture the portion of the thrombus within the net-like filament mesh structure; and withdrawing the thrombus extraction device from the body to remove thrombus from the patient. 本文中公开了从患者体内的血管移除血栓的系统和方法。该方法可包括：提供血栓提取装置，该血栓提取装置包括近侧自扩展构件、远侧大致圆柱形部分和内轴构件，近侧自扩展构件由整体有孔结构形成，远侧大致圆柱形部分由网络状丝网状结构形成，内轴构件连接至网络状丝网状结构的远端；使约束血栓提取装置的导管前进通过脉管血栓，展开血栓提取装
