Abstract

A prosthetic valve assembly includes an annular frame having an inner radial surface, an outer radial surface, and defining an inner lumen. The prosthetic valve assembly further includes a leaflet assembly including at least one leaflet having an inner radial surface and an outer radial surface. The at least one leaflet is disposed at least partially within the inner lumen of the annular frame. The prosthetic valve assembly includes a crimping accessory device having a handle and at least one shielding member removably disposed between the outer radial surface of the at least one leaflet and the inner radial surface of the annular frame. The at least one shielding member is configured to reduce physical contact between the at least one leaflet and the inner radial surface of the annular frame.
