#$%^&*AU2018202664A120180510.pdf#####ABSTRACT The present disclosure relates to valve replacement devices that are foldable for catheterbased deployment to the site of implantation, as well as systems for the delivery of valve 5 prostheses, including prostheses having the special characteristics of the disclosed valve replacement devices. The devices include highly effective adhering mechanisms for secure and enduring precision implantation. The adhering mechanisms may employ a unique sealing mechanism that includes a cuff that expands slowly whereby the device is not secured in place until the completion of the implantation procedure. The implanted 10 device, optionally together with the cuff, prevents perivalvular leaks and incorporate an appropriate leaflet system for reliable functioning in situ.
