摘要
PROBLEM TO BE SOLVED: To provide a device useful for preventing a perivalvular leak associated with an implanted heart valve.SOLUTION: Prosthetic heart valve support cuffs 110 comprise a foamy material 200. The support cuffs may be configured with support frames 130 configured to maintain an improved implantation site for percutaneously delivered heart valves 140. The support cuffs may be implanted either prior to implantation of a heart valve or concurrently with the heart valve. The foamy material is configured to compress and expand upon liquid contact to substantially seal the perimeter of an opening to a heart.
