摘要
The present invention relates to a lower extremity vein thrombus eliminator using a thrombus collecting mesh and a thrombus suction catheter, and a method of using the same, and more specifically, as a lower extremity vein thrombus eliminator using a thrombus collecting mesh and a thrombus suction catheter, closed by a thick thrombus. Introducer (introducer) having a guide wire that is mounted by going up to the normal vein through the lesion of the vein; A sheath guided along the guide guide tube and mounted at an appropriate blood vessel position for removing blood clots from a vein; A blood clot removal net that is mounted on a catheter inserted into the sheath and spreads through a blood clot in a normal blood vessel; And a suction catheter inserted into the sheath to suck the blood clots collected in the clot removal net. According to the lower extremity vein thrombus eliminator using a blood clot collection net and a thrombus suction catheter proposed in the present invention, and a method of using the same, a guide wire provided with a guide wire that goes up to a normal vein through a lesion of a vein closed by a thick thrombus. The sheath is guided along the tube and the guiding tube and placed at an appropriate blood vessel location for removal of blood clots from the vein, the clot removal net that is mounted on the catheter that is inserted into the sheath and spreads from the normal blood vessel through the blood clot, and is inserted into the sheath. By including an inhalation catheter that sucks blood clots collected in the clot removal net, it is possible to easily remove clots in veins closed by thick clots without depending on the skill of the operator. In addition, according to the lower extremity vein thrombus eliminator using a thrombus collecting net and a thrombus suction catheter of the present invention, and a method of using the same, the venous thrombus can be collected and removed by aspiration using a thrombus removal net and a suction catheter, so that the thickness is increased. It can be applied to various blood vessels, and in particular, it is possible to minimize unnecessary bleeding, upper embolization, blood vessel damage, residual blood clots, and blood loss in curved and curved veins.
