PERCUTANEOUS AORTIC VALVE ASSEMBLY |
摘要 |
The present invention provides devices and methods for the treatment of cardiovascular valve diseases such as aortic stenosis. A vascular valve assembly is formed from two or more valve devices, each of which contains a valve mounted in a stent. The individual valve devices are brought to the site of the defective valve by standard percutaneous catheterization methods. Lateral expansion of the stents at the site of valve replacement produces a functioning valve assembly. Appropriate sizing and number of valve devices prevents regurgitation and migration. The assembly of two or more smaller valve devices at the site of a defective valve prevents complications due to the large size of single valve prostheses. |
