Problems solved by technology

[0017] To date, the main problem with the implantation of conventional bioprosthetic heart valves is that the native tissue material can become calcified, leading to undesired stiffening or degeneration of the prosthetic heart valve

Embodiment Construction

[0174] figure 1 A view of a flat tissue pattern of a prosthetic heart valve 100 is shown, according to an exemplary disclosed embodiment. The prosthetic heart valve 100 may include at least two leaflets, and as figure 1 Three leaflets 102 are included as shown in the exemplary embodiment of the flat tissue pattern for a prosthetic heart valve 100 depicted in FIG. Each leaflet 102 includes natural tissue and / or synthetic material. Leaflets 102 are attached to skirt portion 103 . As will be discussed in detail subsequently, skirt portion 103 is used to mount prosthetic heart valve 100 to stent 10 .

[0175] The leaflets 102 of the prosthetic heart valve 100 are adapted to move from a first open position for opening the ventricle and a second closed position for closing the ventricle. Specifically, in the implanted state of the prosthetic heart valve 100, the leaflets 102 are switchable between their first and second positions in response to blood flow through the patient's h...

Abstract

The invention relates to a prosthetic heart valve (100) for use as an endoprosthesis (1) in the treatment of stenotic heart valves and / or valvular insufficiencies. an artificial heart valve (100) comprising a plurality of leaflets (102) constructed of natural tissue and / or synthetic material and having a first open position for opening the ventricle and a second closed position for closing the ventricle, The leaflets (102) are switchable between their first and second positions in response to blood flow through the heart. In addition, the artificial heart valve (100) includes a leaflet support portion (103) made of biomaterials and / or synthetic materials for mounting the artificial heart valve (100) on the support (10), and forms the leaflets (102) and Bendable transition zone (104) of the coaptation zone between the leaflet support parts (103), the transition zone (104) develops substantially in a U-shaped manner, similar to a native aortic or pulmonary valve (pulmonary? heart? valve) The cusp shape of the leaflet (102) serves to reduce tissue stress during the opening and closing actions of the leaflet (102). The invention also relates to an endoprosthesis (1) comprising a prosthetic heart valve (100) and a stent (10).

Description

technical field [0001] The present disclosure relates to a prosthetic heart valve. In particular, the present disclosure relates to a transcatheter-delivered endoprosthetic prosthetic heart valve for use in the treatment of stenotic heart valves and / or valvular insufficiency. [0002] The present disclosure also relates to a transcatheter-delivered endoprosthesis comprising a prosthetic heart valve and a stent for positioning and anchoring the prosthetic heart valve at an implantation site in a patient's heart. In particular, the present disclosure also relates to collapsible and expandable prostheses incorporating artificial heart valves and stents that can be delivered to the site of implantation using a catheter for the treatment of heart valve stenosis (narrowing) and / or heart valve insufficiency . Background technique [0003] The phrase "valve narrowing (stenosis) and / or valve insufficiency" can include a defect in the function of one or more of the heart valves, whi...
