Abstract:
1. A method for modifying tissue in a patient, the method comprising: advancing a flexible distal portion of an elongate tissue modification device into a patient and along a curved path between a target tissue and a non-target tissue, and advancing a flexible distal portion of a guidewire coupled with the flexible distal portion of the elongate tissue modification device outside the patient through a location that is separate from a location where the device was advanced into the patient; positioning a movable blade disposed along one side of the flexible distal portion of the elongate tissue modification device adjacent the target tissue such that the blade faces the target tissue and does not face the non-target tissue; urging the movable blade against the target tissue by fixing the distal end of the elongate tissue modification device relative to the patient and pulling a proximal end of the elongate tissue modification device in a proximal direction; and moving the movable blade towards a second blade to cut the target tissue without significantly translating the elongate tissue modification device in the proximal direction or a distal direction.
