Abstract
The present disclosure is directed to a device. The device may include a distal shaft defining a central lumen and an orienting element comprising at least one inflatable member. Wherein a first portion of the orienting element extending from the shaft in a first direction and a second portion of the orienting element extending from the shaft in a second direction. Further, wherein the second direction is substantially opposite the first direction.
Claims20
A method of facilitating treatment via a vascular wall defining a vascular lumen containing an occlusion therein, comprising:
- advancing a crossing device within the vascular lumen to a location proximal of the occlusion;
- advancing a distal tip of the crossing device into the vascular wall;
- advancing the crossing device distally between an intima of the vascular wall and an adventitia of the vascular wall until the distal tip of the crossing device is disposed at a location distal of the occlusion;
- positioning a guidewire through a lumen of the crossing device to the location distal of the occlusion;
- withdrawing the crossing device from the vascular wall while maintaining a position of the guidewire within the vascular wall;
- advancing an orienting device over the guidewire and within the vascular wall until a first aperture of a shaft of the orienting device is disposed distal of the occlusion;
- withdrawing the guidewire from the orienting device;
- advancing a distal tip of a re-entry device through the orienting device and out the first aperture toward the vascular lumen distal of the occlusion.
