Abstract
A method of treating a lesion in a body lumen to enlarge a passageway in the lumen including inserting a cutting member and tracking member through a first lumen of a catheter, withdrawing the catheter from the cutting member and tracking member, inserting the catheter over the tracking member and leaving the cutting member outside the catheter, and expanding a portion of the catheter to move the cutting member into cutting contact with the lesion. A device for treating a lesion in a body lumen including a cutting member and tracking member is also provided.

1-20. (canceled)
A device for treating a lesion in a body lumen to enlarge a passageway in the body lumen, the device comprising a cutting member having a proximal portion and a distal portion and a tracking member having a proximal portion and distal portion, the cutting member and tracking member being connected at a distal portion and insertable into the body lumen as a unit, the cutting member configured for movement in a direction transverse to a longitudinal axis of the tracking member to widen a gap between the cutting member and tracking member at least at a distal region.
A system for treating a lesion in body lumen to enlarge a passageway in the body lumen comprising:
- a catheter having a lumen and an expandable portion;
- and
- a cutting assembly including a cutting member and a tracking member, the tracking member attached to the cutting member, wherein the expandable portion of the catheter is expandable to move the cutting member in a direction transverse to a longitudinal axis of the tracking member, the cutting member having a cutting surface configured to treat the lesion to enlarge the passageway in the body lumen when moved by the expandable portion of the catheter.
