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 with a lumen extending therein; inserting the device into the vascular lumen; positioning the distal portion in the vascular wall; and directing the distal portion within the vascular wall.
Claims20
A method of treating an occlusion of a blood vessel, comprising:
- advancing an intravascular device within a lumen of the blood vessel to a position proximate the occlusion, wherein the intravascular device comprises:
- an elongate shaft defining a central longitudinal axis;
- an inflatable balloon secured to the elongate shaft, the inflatable balloon including an expandable portion;
- a first lumen;
- and
- a second lumen extending coaxially with the central longitudinal axis to a distal opening positioned distal of the expandable portion of the inflatable balloon;
- inflating the inflatable balloon to expand the expandable portion and orient a distal opening of the first lumen toward an intimal layer of a wall of the blood vessel;
- advancing a subintimal device through the first lumen upon expansion of the expandable portion and through the intimal layer of the wall of the blood vessel.
A method of treating an occlusion of a blood vessel, comprising:
- advancing an intravascular device within a lumen of the blood vessel to a position proximate the occlusion, wherein the intravascular device comprises:
- an elongate shaft defining a central longitudinal axis;
- an inflatable balloon secured to the elongate shaft, the inflatable balloon including an expandable portion;
- a first lumen extending along an exterior surface of the expandable portion of the inflatable balloon;
- and
- a second lumen extending coaxially with the central longitudinal axis to a distal opening positioned distal of the expandable portion of the inflatable balloon;
- inflating the inflatable balloon to expand the expandable portion and orient a distal opening of the first lumen toward an intimal layer of a wall of the blood vessel;
- advancing a subintimal device through the first lumen upon expansion of the expandable portion and through the intimal layer of the wall of the blood vessel.

- wherein a distal opening of the first lumen is positioned intermediate a proximal end of the expandable portion and the distal end of the expandable portion;
- inflating the inflatable balloon to expand the expandable portion and orient the distal opening of the first lumen toward an intimal layer of a wall of the blood vessel;
- advancing a subintimal device through the first lumen upon expansion of the expandable portion and through the intimal layer of the wall of the blood vessel.
