摘要:
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.
