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 system for bypassing an occlusion in a blood vessel, comprising:
- an intramural orienting device comprising:
- an elongate shaft including a lumen extending therein to a distally facing opening at a distal end of the elongate shaft;
- and
- an orienting element including two wings configured to shift between a collapsed delivery configuration and an expanded deployed configuration, the two wings being monolithically formed with a portion of the elongate shaft;
- wherein in the expanded deployed configuration, the two wings extend outwardly from the elongate shaft in a substantially planar manner;
- wherein a distal portion of the elongate shaft includes a side opening in communication with the lumen, the side opening facing orthogonally relative to the two wings.
A system for bypassing an occlusion in a blood vessel, comprising:
- an intramural orienting device comprising:
- an elongate shaft including a lumen extending therein along a central longitudinal axis of the elongate shaft to a distally facing opening at a distal end of the elongate shaft;
- and
- an orienting element including a first wing and a second wing configured to shift between a collapsed delivery configuration and an expanded deployed configuration, the first wing and the second wing being monolithically formed with a portion of the elongate shaft;
- wherein in the expanded deployed configuration, the first wing and the second wing extend laterally from the elongate shaft in opposite directions from the central longitudinal axis;
- wherein a distal portion of the elongate shaft includes a side opening in communication with the lumen, the side opening facing orthogonally relative to the first wing and the second wing.
