Abstract
A system and method for resecting a valve in a patient, in which the system includes: a proximal frame and a distal frame opposite the proximal frame, each frame including a plurality of interconnectable frame segments, in which the proximal and distal frames are separated by an adjustable distance and positionable on opposite sides of the valve; an electrode, adjacent to the valve on at least one of the proximal and distal frames, that electrosurgically resects valve tissue; a proximal chamber and a distal chamber coupled to the proximal and distal frames, respectively, that allow passage of fluid and captures at least a portion of resected valve tissue, in which each chamber selectively operates in one of a radially collapsed mode and a radially expanded mode; and a drive system that adjusts the distance between the proximal and distal frames.
