| 主权项 | 1. A sensing device for measuring a property of tissue for selecting a collapsible prosthetic heart valve, the sensing device comprising: an elongated shaft having a proximal end and a distal end; a rigid body having an outer surface, the body being coupled to the distal end of the shaft, the body being adapted to fit within a native valve annulus; and at least one microelectromechanical sensor attached to the body and being disposed on the outer surface of the body, the at least one sensor having a deflectable portion and being capable of measuring a property of tissue adjacent to the native valve annulus by contacting the tissue against the deflectable portion. | ||
