Abstract

A delivery device for a prosthetic mitral valve includes five sheaths and a handle. The first sheath is coupled to a first handle portion and is rotatable and bendable. The second sheath is coupled to a second handle portion and extends through the first sheath. The second sheath is bendable, rotatable and translatable relative to the first sheath. The third sheath is coupled to a third handle portion and extends through the first and second sheaths. The third sheath is translatable relative to the second sheath. The second handle portion is coupled to the first and third handle portions. The fourth sheath extends through the third sheath and forms part of a compartment to store the prosthetic valve. The fifth sheath extends through the fourth sheath to a tip and is coupled to a retaining sheath that closes the compartment to retain the valve in a collapsed condition.
