APPARATUS AND METHODS FOR IMPLANTING REPLACEMENT HEART VALVE

摘要

To provide systems and methods for properly docking a heart valve prosthesis.SOLUTION: A system includes a helical anchor 30 formed as multiple coils adapted to support a heart valve prosthesis 10 with coil portions 32 positioned above and below the heart valve annulus 12c. A seal is coupled with the helical anchor and includes portions extending between adjacent coils for preventing blood leakage through the helical anchor and past the heart valve prosthesis. An expansible helical anchor is formed as multiple coils adapted to support the heart valve prosthesis. At least one of the coils is normally with a first diameter, and is expandable to a second, larger diameter upon application of radial outward force from within the helical anchor.SELECTED DRAWING: Figure 7D-1
