The use of autologous tissue-engineered valved stents might solve the problem of degeneration and limited durability of biological heart valves. METHODS AND RESULTS Porcine pulmonary heart valves and small intestinal submucosa were obtained from a slaughterhouse. The intestinal s...
متن کاملDouble-crowned valved stents for off-pump mitral valve replacement.
OBJECTIVE An animal model has been designed to assess the feasibility of off-pump mitral valve replacement using valved stents. METHODS Glutaraldehyde-preserved homograft was sutured inside a prosthetic tube (Dacron). Then, two self-expandable nitinol Z-stents were sutured on the external surface of the prosthesis in such a way to create two self-expanding crowns for fixation. In adult pigs a...

Coronary artery stents were designed to overcome some of the short comings of angi...
متن کاملFlow-based compromise detection
Brute-force attacks are omnipresent and manyfold on the Internet, and aim at compromising user accounts by issuing large numbers of authentication attempts on applications and daemons. Widespread targets of such attacks are Secure SHell (SSH) and Web applications, for example. The impact of brute-force attacks and compromises resulting thereof is often severe: Once compromised, attackers gain a...
