Coronary artery branch support with locating ring

Abstract

The invention patent is a new type of coronary artery stent, which belongs to the innovative technology in the field of medical devices. The coronary stents currently on the market are all uniform cylindrical structures. When the coronary branch vessels or bifurcated vessels need to be stented, due to the relatively complex structure and the beating heart, it is almost impossible to insert a stent in the coronary artery. A stent was placed at the mouth of the arterial branch. The main body of the coronary branch stent with positioning ring moves toward the branch along the branch guide wire, and the positioning ring at the proximal end of the stent slides to the main branch along the main branch guide wire; when the stent reaches the bifurcation of the main branch and the branch, the stent main body has entered the branch, and the proximal Due to the existence of the positioning ring, the end is accurately stuck at the bifurcation, and the bracket can be accurately positioned at the mouth of the branch. The new stent will be innovatively improved for the treatment of branch lesions and the current treatment technology for bifurcation lesions.

Description

technical field [0001] The patent of the present invention is a new type of coronary artery stent, especially related to coronary branch lesions, bifurcation lesions, and coronary stents that need to be placed in the case of accurate positioning. [0002] technical background [0003] In recent years, coronary artery stent technology has become a routine technique for interventional therapy. However, when stents need to be placed in coronary branch vessels or bifurcated vessels, due to factors such as relatively complex structures and the beating heart, it is very difficult to accurately determine the position of the stent. The birth of the stent with a positioning ring will completely change this dilemma, and make a fundamental change and progress in the accurate positioning and surgical methods of coronary artery bifurcation lesions. Contents of the invention [0004] All coronary stents currently on the market are uniform cylindrical structures (11), as shown in the att...
