Transcatheter aorta root covered stent system

Abstract

The invention discloses a transcatheter aorta root covered stent system, and belongs to the field of covered stents.The transcatheter aorta root covered stent system comprises a catheter and a guide wire inserted into the catheter, a supporting mechanism is installed on the surface of the guide wire, a chimney mechanism is installed on the surface of the supporting mechanism, and a protection mechanism is installed in the chimney mechanism; through cooperative use of all the devices, the extrusion plate is pulled to extrude the elastic block, so that the elastic block deforms and is tightly attached to the hollow cylinder, the hollow cylinder is pushed out of the covered stent assembly, the hollow cylinder deforms and resets through the temperature in the body of a patient, and after it is guaranteed that the aorta true cavity is smooth, the hollow cylinder is reset. The covered stent assembly is pushed to be connected to the surface of the hollow cylinder in a sleeving mode and attached to the inner wall of the coronary artery opening, so that circulation of the aorta true cavity is smoother, and the situation that due to conflict between the unique anatomical structure of the aorta root and the mechanical effect of an interventional instrument, the aorta covered stent blocks the aorta root is avoided.
