Abstract
A prosthetic heart valve assembly includes a gasket member and a valve member including a plurality of fasteners and a plurality of engagement members corresponding to the fasteners. The fasteners and/or engagement members may be configured to guide the engagement members into engagement with the fasteners. For example, the fasteners may include U-shaped spring-biased clips, e.g., attached to a core or other portion of a sewing cuff of the gasket member, and the engagement members may include latches or barbed protrusions that engage one or more holes in the fasteners. During use, the gasket member is introduced into a tissue annulus, and secured to the annulus, e.g., using a plurality of clips directed through the sewing cuff. The valve member is then introduced into the annulus and the engagement members are snapped or otherwise guided into engagement with the fasteners to secure the valve member relative to the gasket member.
