The Edwards Lifesciences Llc patent solves the following problem:
Various etiologies can result in heart valve lack both depending on the particular valve as well as the real cause of the disease state of the patient. For example, a congenital defect may have resulted in poor coaptation of the valve leaflets, as in the case of a monocusp aortic valve, for example. Valve also lack resulting from an infection, such as rheumatic fever, for example, causing a shame the valve leaflet. Purely regurgitation today. In such cases, the valve element may be pathologically normal, but may not work properly due to changes in the surrounding environment. Examples of such changes include the geometric change in one or more chambers of the heart and / or reduction of myocardial contractility. In any case, the consequences of volume overload that is as a result of a lack of valve to increase the chamber wall stress. Such an increase in stress may eventually result in a dilatory process of further accelerating valve dysfunction and humbled heart efficiency.
Our analysis of this patent is as follows:
Edwards Lifesciences Llc’s patent US 7666224 B2 deals with Devices and methods for heart valve treatment.
Devices and methods for improving the function of a valve (eg, mitral valve) by placing a filling device outside and adjacent to the heart wall so that the device can be used in an force against the wall of the heart valve operation. A substantially equal and opposite force to be extended to take the power of the heart wall, and / or a substantially equal and opposite to the external force used against the anatomical structure of the wall of the heart. The inner forces is enough to change the function of the valve, and increase coaptation of the leaflets, for example. The space filling device can be implanted in a surgical way, a transthoracic approach, or on a transluminal manner, for example. The space filling portion may be delivered using a delivery catheter sailed through the chosen way, and the space filling portion be expandable between a smaller configuration delivery and a greater deployment configuration.
