摘要： A docking device for a bioprosthesis is disclosed that can change shape and recover after a deforming stress is removed, that adjusts to surrounding conditions to accommodate different complex anatomic geometries, and that mitigates leakage around the bioprosthesis. The docking device can include a 3D woven fabric forming an internal surface, an outer surface, and a thickness therebetween. A filler can be coupled to the outer surface. A method for making a docking device is also provided. The method includes weaving a 3D woven fabric by interlacing a shape memory material, a low-melt thermoplastic polymer or resin having a melting point, and a high-tenacity biocompatible material; and pressing and heating the 3D woven fabric over a shape-setting mold at temperatures greater than the melting point of the low-melt thermoplastic polymer or resin.

摘要： A loader and method for loading a transcatheter heart valve into a delivery sheath or catheter is described that is also configured to facilitate retrieval of the heart valve back through the delivery sheath while protecting the delivery sheath from damage. Another loader provides for easier crimping and loading of a THV into a delivery sheath or catheter from a storage jar or container. A method for crimping a THV facilitates easier end user preparation of the valve for implantation and reduces the likelihood of tissue deformation in the valve during storage. These devices and methods for deploying THVs simplify the valve replacement procedure.

摘要： A method of fabricating a docking device involves implementing a three-dimensional (3D) weaving technique to form a 3D textile structure using a plurality of different types of fibers, heating the 3D textile structure on a shape-setting mold at a temperature above a melting point of a first type of fiber of the plurality of different types of fibers to set a cylindrical shape of the 3D textile structure, maintaining the 3D textile structure on the shape-setting mold to cool off for a period of time, and removing the 3D textile structure from the shape-setting mold.

摘要： A delivery apparatus for implanting a radially compressible and expandable prosthetic heart valve in a native heart valve of the heart includes a handle portion and an elongated shaft extending from and movable relative to the handle portion. The shaft includes a proximal end portion coupled to the handle portion and a distal end portion configured to mount a prosthetic heart valve in a radially compressed state. The handle portion includes a control member movable longitudinally with respect to the handle portion, the control member engaging a gear assembly operable to convert longitudinal motion of the control member to rotational motion of the gear assembly. The gear assembly engages the elongated shaft such that rotational motion of the gear assembly causes corresponding longitudinal motion of the elongated shaft relative to the handle portion.

摘要： Embodiments of a radially collapsible and expandable prosthetic heart valve are disclosed. The prosthetic valve can comprise an annular frame, leaflets, an inner skirt, and an outer skirt. The outer skirt can be secured to the outside of the inflow end portion of the frame, the outer skirt having longitudinal slack that buckles outward radially when the valve is in the expanded configuration and which lies flat when the valve is in the collapsed configuration. In some embodiments, the outer skirt is stiffer in the axial direction of the valve than in the circumferential direction of the valve. In additional embodiments, the outer skirt comprises a self-expandable fabric comprising fibers made of a shape memory material having a shape memory set to enhance the radially outward buckling of the outer skirt. Methods of crimping such valves to a collapsed or partially collapsed configuration are also disclosed.
