Abstract
A system for determining the dimensions of a native valve annulus may include a sensing catheter, a transmitter, and a computing device. The sensing catheter may include a shaft extending in a longitudinal direction; a plurality of splines attached to the shaft, the splines having an expanded condition spaced radially outward from the shaft; and at least one sensing coil located on each of the splines. The transmitter may generate a magnetic field to induce a potential in each of the sensing coils, and the computing device may identify the positions of the sensing coils based on the induced potentials.
