Problems solved by technology

However, despite the significant hemodynamic benefits of such unsupported bioprosthetic valves, implantation of this type of prosthetic valve is more difficult than traditional bioprosthetic valves with struts and the sewing ring positioned at the peripheral edge of the stent
[0019] This deficiency is particularly reflected in the increased need for intraoperative cardiac arrest and use of extracorporeal blood circulation and the increased chance of misimplanting the prosthetic valve on a vital structure close to the point of implantation
[0020] Bioprosthetic valves are common, and another disadvantage of artificial valves without supports is that since there is no device that can rotate the artificial valve on the sewing ring, in situ orientation (i.e. after implantation) cannot be achieved.
[0030] —Once the prosthetic valve is sewn to the appropriate anatomical structure, rotation cannot be relied upon to adjust the orientation of the valve; and

Embodiment Construction

[0041] For a better understanding of the terms used in the detailed description of the invention, short definitions are provided below.

[0042] Bioprosthetic valve: A substitute for a heart valve that is partially or wholly made of a substance of biological origin, usually of animal origin. The most important structural components of bioprosthetic valves are "valve strips" made of biological materials (bovine pericardium or porcine heart valve strips) and "supporting structures" made of plastic materials (so-called "stents"); The "support structure" (stent) is absent in so-called stentless prosthetic valves (unsupported).

[0043] Sewing Ring: It is a ring made of synthetic material.

[0044] In traditional and known prosthetic heart valve devices all these components ("valve strip", "stent", "sewing ring") are assembled in a certain way in their manufacture so as to form a single body, and there is no It is possible to separate these components from each other in subsequen...

Abstract

A prosthetic valve apparatus (10), in particular for cardiac applications. The apparatus (10) comprises a valve prosthesis (20) fastened to a suture ring (30). The apparatus (10) further provides for the valve prosthesis (20) to be fastened to the suture ring (30) by means of a plurality of magnets (21d, 30b) which provide a magnetic attraction between the two components.

Description

technical field [0001] The present invention generally relates to the field of medical prosthetic devices, and in particular, generally relates to a prosthetic valve device capable of being implanted in the body region of a human or mammal. Background technique [0002] The scope of the present invention is in the field of medicine, and in particular in the field of cardiac surgery, aimed at the treatment of congenital or acquired valvular diseases for which it is indicated to replace a valve irreversibly damaged by a pathological process of different etiology with an artificial valve. or multiple natural heart valves. [0003] Replacing one or more heart valves with artificial valves is a long-established procedure. Such surgical procedures typically require the use of extracorporeal blood circulation, which enables access to the heart chambers while the heart is stopped and bloodless. [0004] However, despite the rapid development in the field of cardiac surgery, it can...
