System and method for delivery of specific transapical heart of the self-expanding valve, which is fixed to the annulus

摘要

Prosthetic valve assembly for use in the replacement of defective native valve is replacement valve that is supported on the frame of the expandable prosthesis comprises a (820). The valve (820) may be using other limited close approach using thoracoscopic or delivery catheter (920) is via tube or through the myocardium delivered. The first partial extension of the valve (820) is performed for the original annulus (916), when a remaining part extends, is suitable fastening and positioning of the valve (820) provided in the valve (820) it is preferred that the. The valve (820) can be delivered using a retrograde or antegrade approach. When delivered using retrograde approach, resulting in use delivery catheter (920) is having a sheath (922) for retraction, whereas, antegrade delivery, first, proximal end of the valve (820) opening the, it is preferably conducted using a delivery catheter (920) having an extrusion sheath (922).
