Abstract
Devices and methods for assessing the orientation and shape of vessel lumens and hollow portions of organs are described. The devices and methods are particularly adapted for determining the orientation and shape of the native heart valves to facilitate the later implantation of a prosthetic heart valve. The devices are typically catheter-based having an expandable member fixed to a distal end of the catheter. Located within the expandable member is an ultrasonic imaging probe and an acoustic reflective material. The methods typically comprise deploying the balloon percutaneously to a target location, expanding the balloon, and determining the orientation and shape of a lumen, particularly a cardiac valve.
