Benefits of technology

The technical effect of this new technique involves removing an abnormal heart valve from its blood vessels before performing it on another patient's body during open chest surgeries without causing complication or other issues that may affect their healthcare costs for patients who are unable to receive treatment due to these procedures.

Problems solved by technology

Technologies aim at improving heart function by replacing damaged hearts during surgerys without causing significant patient disorders like bleeding from artificial valves and thromboembolisms associated with these prosthetic devices. Current techniques involve invasive procedures involving open chest operations, thoracotomy, catheter placement within the right side of the heart called transcraniectomy, and minimizing risks involved while maintaining good outcomes overall.

Embodiment Construction

[0043] The present invention will be further described below in conjunction with the embodiments shown in the drawings.

[0044] An aortic valve stent 30 (such as figure 1 Shown), which includes a tubular stent 2 and a tri-leaf valve 4, and also includes a coronary stent 9 ( image 3 ), the tubular stent 2 includes a proximal end 7 and a distal end 8 of the stent. The proximal end 7 of the stent is provided with coronary artery stents 9 on the left and right ends, and the proximal end 7 of the stent is lined with a tri-leaflet valve 4 ( figure 1 with figure 2 ).

[0045] Among them, the tubular stent 2 has a mesh structure. The proximal end 7 of the stent has three sinus portions 6 of the valve stent, and the sinus portion 6 of the valve stent is slightly bulged to coincide with the coronary sinus of the heart. The coronary stent 9 is of a rivet type. The enlarged portion 10 of the coronary stent 9 is embedded in the central mesh of the sinus wall of the proximal end 7 of the aor...

Abstract

The utility model belongs to the technical field of medical instruments, and relates to an aortic valve stent with a coronary artery and a conveyor of the aortic valve stent. The aortic valve stent comprises a tubular stent body (2) and a tricuspid valve (4), and further comprises coronary artery stents (9); and the tubular stand body (2) comprises a stent proximal end (7) and a stent distal end (8), wherein the coronary artery stents (9) are arranged at the left and the right ends of the stent proximal end (7), and the stent proximal end (7) is lined with the tricuspid valve (4). Compared with other interventional valves, the aortic valve stent has good biological compatibility, is fixed firmly, ensures that the blood in the coronary artery flows smoothly, is designed with an in vivo positioning device, a perivalvular leakage prevention device and a recovery device (a recovery line), can improve or overcome the problems of biological compatibility, in vivo positioning, influence on the blood flowing of the coronary artery, unrecovery, perivalvular leakage and the like.
