THROMBUS-TAKING STENT, THROMBUS-TAKING DEVICE AND THROMBUS-TAKING SYSTEM

摘要

A thrombus-taking stent (1) comprises rigid units (11) and flexible units (12) which are connected in a staggered manner; all the rigid units (11) and the flexible units (12) are of a tubular structure capable of realizing radial compression and expansion; and the flexible units (12) are more flexible than the rigid units (11), and under an equivalent external force, the flexible units (12) are more prone to being deformed compared with the rigid units (11). A thrombus-taking device (100) comprises the thrombus-taking stent (1) and a traction guiding wire (2) connected to the thrombus-taking stent (1). Moreover, a thrombus-taking system comprises the thrombus-taking device (100), a push rod (200), a loading sheath (300) and a micro catheter (400), wherein the push rod (200) is connected to the thrombus-taking stent (1) and is used for pushing and pulling the thrombus-taking stent (1); the loading sheath (300) is used for accommodating the thrombus-taking device (100); and the micro catheter (400) is in communication with the loading sheath (300) and is used for conveying the thrombus-taking device (100). Such structure may increase the success rate of taking thrombi, and further improve the capability of catching thrombi.
