摘要
A prosthetic heart valve is circumferentially collapsible for less invasive delivery into a patient. The valve re-expands to operating size at the implant site in the patient. A frame structure of the valve includes restraining structure that can help to push one or more of the patient's native heart valve leaflets radially outwardly so that this native leaflet tissue does not interfere with the operation or service life of the prosthetic valve.
