Abstract
Some embodiments are directed to methods and systems for percutaneously treating dissections in a patient's vasculature, such as, without limitation, the aorta. The method can include deploying a catheter containing a collapsed anchoring element, frame, and cover through a first vessel to an entry point of the dissection. The anchoring element can be secured to the second branch vessel. The frame can be expanded in the first branch vessel. The cover can be unfolded over at least a portion of the entry point. The cover then reduces blood flow into the entry point.
Claims15
A device for treating a vascular dissection, comprising:
- an anchoring element configured to be deployed outside of a first vessel within a second vessel in communication with the first vessel having the vascular dissection, the anchoring element having a generally tubular structure comprising a first end and a second end, the first end having a first opening into the first vessel which defines a first plane;
- a single elliptical frame that is configured to cover an entry point of the vascular dissection, a circumference of the elliptical frame being substantially coplanar with the first opening, the single elliptical frame attached to the anchoring element and configured to conform to a wall of the first vessel;
- and
- a cover supported by the single elliptical frame.

- and
- a single elliptical frame that is configured to cover an entry point of the vascular dissection, and conform to a wall of the first vessel;
- and
- a cover supported by the single elliptical frame,
- wherein the first end of the anchoring element is attached to the elliptical frame such that the first opening is positioned between a proximal and a distal end of the elliptical frame.
