Abstract

See full text

The present invention provides a valvuloplasty device having a plurality of expandable chambers for valvuloplasty such that the arrangements and disposition of the expandable chambers conforms to the anatomy of the valve to be treated, thereby increasing the likelihood that inflation of the balloons will restore the valve more closely to its original anatomy and function. The expandable chambers can be expanded in various combinations or sequences in order to provide improved results from the treatment. The present invention also provides a method of performing valvuloplasty in which a plurality of expandable chambers having a fixed geometric relationship to each other are positioned within the valve to be treated and the expandable chambers are expanded in combination and/or in sequence to provide improved anatomical structure and function of the valve treated by the method.
