Patent ID: 8062300

Claim:
A system for modifying tissue in a patient, the system comprising: a tissue modification device comprising: an elongate body having a proximal portion, and a flexible distal portion having opposing first and second major surfaces extending longitudinally; one or more tissue modifying members disposed along the first major surface, wherein the second major surface is an atraumatic surface; and a guidewire coupler near the distal end of the body configured to retain the proximal end of a guidewire relative to the guidewire coupler so that the tissue modification device may be pulled distally by pulling the guidewire distally and so that the tissue modification device may be released from the guidewire by pushing the guidewire proximally; a proximal handle configured to couple with the proximal portion of the tissue modification device; a guidewire configured to couple to the tissue modification device; and a distal handle configured to couple with the guidewire outside of the patient.
