1. A method for performing valvuloplasty, the method comprising:
- first, percutaneously delivering an expandable braid to a valvuloplasty site within a patient;
second, expanding the expandable braid to perform the valvuloplasty;
third, measuring foreshortening of the expandable braid during the valvuloplasty;
fourth, determining a diameter of the expandable braid during the valvuloplasty from the foreshortening measurement; and
fifth, allowing blood flow through the expandable braid during the valvuloplasty.
