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 inserting an intramural crossing device into the vascular lumen, positioning at least the distal tip of the crossing device in the vascular wall, advancing an orienting device over the crossing device such that an orienting element of the orienting device resides in the vascular wall, inserting a reentry device, and re-entering the true vascular lumen.
Claims20
A method of bypassing an occlusion in a blood vessel through a subintimal pathway, comprising:
- advancing a subintimal crossing device through a subintimal space between tissue layers of a vascular wall of the blood vessel adjacent to the occlusion;
- thereafter, advancing an orienting device into the subintimal space;
- expanding an orienting element of the orienting device in the subintimal space to orient a side port of the orienting device toward a lumen of the blood vessel distal of the occlusion;
- and
- advancing a re-entry device out of the side port and into the true lumen of the blood vessel distal of the occlusion.
A method of bypassing an occlusion in a blood vessel through a subintimal pathway, comprising:
- advancing a subintimal crossing device through a subintimal space between tissue layers of a vascular wall of the blood vessel adjacent to the occlusion, the subintimal crossing device having a bulbous distal tip and a guidewire lumen extending therethrough;
- thereafter, withdrawing the subintimal crossing device from the subintimal space;
- thereafter, advancing an orienting device over a guidewire into the subintimal space;
- expanding an orienting element of the orienting device in the subintimal space to orient a side port of the orienting device toward a lumen of the blood vessel distal of the occlusion;
- and
- advancing a re-entry device out of the side port and into the true lumen of the blood vessel distal of the occlusion.
