Zusammenfassung:	A device for treating a lesion in a body lumen to enlarge a passageway in a body lumen comprising a cutting member having a proximal portion and a distal portion and a tracking member having a proximal portion and a distal portion. The cutting member and tracking member are connected at their distal portions 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. Un appareil de traitement dune lésion dans une lumière corporelle pour élargir un passage dans une lumière corporelle comprend un élément de coupe ayant une portion proximale et une portion distale et un élément de suivi ayant une portion proximale et une portion distale. Lélément de coupe et lélément de suivi sont connectés à leurs portions distales et insérables dans la lumière corporelle comme une unité, lélément de coupe étant configuré pour un mouvement dans une direction transversale à un axe longitudinal de lélément de suivi pour élargir un espace entre lélément de coupe et lélément de suivi au moins à une région distale.
