Abstract
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.
