摘要： Docking stations for transcatheter valves are described. The docking stations can include an expandable frame, at least one sealing portion, and a valve seat. The expandable frame can be configured to conform to an interior shape of a portion of the circulatory system when expanded inside the circulatory system. The sealing portion can be configured to contact an interior surface of the circulatory system to create a seal. The valve seat can be connected to the expandable frame and can be configured to support an expandable transcatheter valve. The docking stations are adaptable to different anatomies/locations to allow implantation of a transcatheter valve in a variety of anatomies/locations.

摘要： The expandable sheath and methods of use disclosed herein are used to deliver a prosthetic device through a patient's vasculature. The sheath is constructed to be expandable in the circumferential direction, while maintaining sufficient stiffness in the longitudinal direction to withstand pushing and resist kinking. The sheath includes a plurality of curved arms extending outwardly from a longitudinally extending spine. The curved arms move away from the longitudinal axis of the sheath when pushed radially outwardly by a passing prosthetic device, and move back toward the longitudinal axis once the prosthetic device has passed.

摘要： Various mechanically expandable prosthetic heart valves, as well as deliver apparatus, delivery assemblies, and methods for implanting such prosthetic heart valves. In one example, a prosthetic heart valve includes a mechanically expandable frame, a valve structure, and an actuator. The frame includes a plurality of struts and is movable between a radially compressed state and a radially expanded state. The valve structure includes a plurality of leaflets. The actuator is coupled to the frame and comprises an actuation lumen, a locking member, and a locking element. The actuation lumen is circumferentially spaced and axially parallel to the locking member. The actuation lumen is configured for receiving an axially movable actuation shaft that can move the frame between the radially compressed state and the radially expanded state. The locking element is rotatably coupled to the locking member and is configured to lock the frame at a desired state.

摘要： An implantable prosthetic valve can include a frame movable between a radially compressed and a radially expanded configuration. The frame can include a first strut having a first locking feature disposed on a radially facing inner surface of the strut and a second strut having a second locking feature disposed on a radially facing outer surface of the strut. The first and second locking features can engage each other so as to allow pivoting of the first and second struts relative to one another in a first direction upon radial expansion of the frame and resist pivoting of the first and second struts relative to one another in a second direction to resist radial compression of the frame.
