APPARATUS AND METHOD FOR MONITORING VALVE EXPANSION

Abstract

Embodiments of a prosthetic valve delivery apparatus are disclosed. The delivery apparatus can include an indicator arm changeable between a first configuration and a second configuration. The second configuration is different from the first configuration in location or shape of the indicator arm. The indicator arm can be configured to remain in the first configuration when a diameter of the prosthetic valve is smaller than a first predetermined size, and change to the second configuration when the diameter of the prosthetic valve is expanded to the first predetermined size.
