Abstract
Devices and methods for the treatment of chronic total occlusions are provided. One disclosed embodiment comprises a method of facilitating treatment via a vascular wall defining a vascular lumen containing an occlusion therein. The method includes providing an intravascular device having a distal portion, inserting the device into the vascular lumen, positioning the distal portion in the vascular wall to at least partially surround the occlusion, and removing at least a portion of the surrounded occlusion from the lumen.

1-22. (canceled)
A medical device, comprising:
- a catheter including:
- a first tubular member defining a first lumen configured to receive a guidewire;
- an expandable member located about the first tubular member;
- and
- a second tubular member having a proximal end and a distal end, the second tubular member defining a second lumen having an outlet at the distal end of the second tubular member, the second tubular member adjacent an outer surface of the expandable member and configured to move radially away from a central axis of the first tubular member as the expandable member expands.
A medical device, comprising:
- a subintimal device;
- and
- a catheter including:
- a first tubular member defining a first lumen configured to receive a guidewire;
- an inflatable member located about the first tubular member;
- and
- a second tubular member having a proximal end and a distal end, the second tubular member defining a second lumen configured to receive the subinitimal device, the second tubular member adjacent an outer surface of the inflatable member and configured to move radially away from a central axis of the first tubular member as the inflatable member inflates.
A method of treating a vascular wall defining a vascular lumen, the vascular wall comprising an intima and an adventitia, the method including:
- inserting a catheter into the vascular lumen, the catheter including a first tubular member defining a first lumen, an inflatable member located about the first tubular member;
- and a second tubular member defining a second lumen having an outlet, the second tubular member adjacent an outer surface of the inflatable member;
- inflating the inflatable member to move the second tubular member radially away from a central axis of the first tubular member;
- and
- injecting fluid out of the outlet of the second lumen and into the vascular wall.
