1. A device for modifying and/or removing obstructive material from a lumen of a blood vessel, the device comprising:
an elongated member having a proximal portion and a distal portion configured to be intravascularly positioned at a treatment site in a blood vessel adjacent obstructive material;
a cutting portion disposed at the distal portion of the elongated member, the cutting portion including a cutting element, wherein the cutting portion has a collapsed, low-profile state for delivery to the treatment site and a deployed state for cutting obstructive material at the treatment site, and wherein the cutting element extends radially away from a longitudinal axis of the elongated member in the deployed state; and
a capturing portion disposed at the distal portion of the elongated member, wherein the capturing portion is configured to collect obstructive material that has been dislodged by the cutting portion,
wherein the elongated member comprises a first elongated member and a second elongated member, and wherein the cutting portion is disposed at a distal portion of the first elongated member and the capturing portion is disposed at a distal portion of the second elongated member, and
wherein the second elongated member is configured to be slidably disposed within a lumen of the first elongated member.
