| 20080221593 | APPARATUS AND METHOD FOR THE LIGATION OF TISSUE - A novel catheter-based system which ligates the left atrial appendage (LAA) on the outside of the heart, preferably using a combination of catheters and/or instruments, e.g., a guide catheter positioned inside the left atrial appendage which may assist in locating the left atrial appendage and/or assist in the optimal placement of a ligature on the outside of the appendage, and a ligating catheter and/or instrument outside the heart in the pericardial space to set a ligating element at the neck of the left atrial appendage. | 09-11-2008 |

| 20090248143 | PERCUTANEOUS AORTIC VALVE ASSEMBLY - 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. | 10-01-2009 |
