Intervention bioprosthetic valve with valve leaflet capable of being replaced repeatedly through minimally invasive surgery

Abstract

The invention discloses an intervention bioprosthetic valve with a valve leaflet capable of being replaced repeatedly through minimally invasive surgery. The intervention bioprosthetic valve comprises a valve frame and the valve leaflet, wherein the valve frame and the valve leaflet are independent from each other, the valve frame and the valve leaflet can be installed on a valve ring in a minimally invasive intervention mode, and the valve leaflet can be demounted and mounted in the minimally invasive intervention mode. When the intervention bioprosthetic valve is implanted in a patient in a minimally invasive mode and the intervention bioprosthetic valve needs replacement due to the fact that functional degradation happens to the valve leaflet, a conveyer device provided with a new valve leaflet can be guided by a visualization device to remove the broken valve leaflet through the new valve leaflet on the conveyer device through minimally invasive surgery, meanwhile, the new valve leaflet is unfolded and installed on the valve frame to complete valve leaflet replacement, then, the broken valve leaflet is contained in the conveyer device and taken out of the body of the patient after being compressed, and therefore the replacement of the heart valve is completed. The design of the valve leaflet capable of being replaced repeatedly through minimally invasive surgery solves the problem of time limit of minimally invasive valve replacement.

AI Technical Summary

Benefits of technology

This patented technology allows for easier access during minimal-invasiveness surgeries while also improving their effect on reducing damage or deteriorating heart functions compared to traditional methods like sternum resection (open chest) techniques. Additionally, it provides support forces between the valvular tissue and its anchoring structure which helps keep them stable when they are being repaired. Overall, this new method offers improved outcomes over existing procedures.

Problems solved by technology

The technical problem addressed in this patented text relates to developing new methods for treating diseases associated with abnormalities (valvuluses) caused by blockage during procedures like mitral valve repair surgeries. Current options involve either permanent closure or temporary occlusion devices, but current solutions may result in longer hospital stays compared to ideal ones.
