Abstract
A device for dividing a fibrous structure comprising an expandable member positioned near the distal end of a catheter and in fluid communication with the lumen of the catheter so that the expandable member can be biased between an inflated state and a deflated state to tension the fibrous structure, and electrosurgical elements situated on or proximate to an outer surface of the expandable member and configured to deliver electrical and thermal energy to the tensioned fibrous structure in a manner that results in division of the tensioned fibrous structure. A method for dividing a fibrous structure comprising positioning proximate the fibrous structure an expandable member having electrosurgical elements, expanding the expandable member outwards to tension the fibrous structure across the electrosurgical elements, and activating the electrosurgical elements to deliver energy to the tensioned fibrous structure to divide the tensioned fibrous structure.
