Abstract
Devices and methods to treat a diseased portion of an aorta. A method of implanting an endoprosthesis within the aorta may include positioning the endoprosthesis within the aorta in a collapsed state with a constraint and deploying the endoprosthesis to the deployed diameter. The aorta has a true lumen and a false lumen due to the aorta having a defect, the true lumen defining a true lumen diameter and the false lumen formed by a false lumen wall defining a false lumen diameter. The deployed diameter of the endoprosthesis is such that the endoprosthesis extends along the true lumen and along at least a portion of the false lumen at a position where the defect is located in the aorta such that the endoprosthesis defines a flow bypass through a diseased portion of the aorta.

A method of implanting an endoprosthesis within an aorta of a patient, the method comprising:
- positioning the endoprosthesis within the aorta in a collapsed state with a constraint, the aorta having a true lumen and a false lumen due to the aorta having a defect, the true lumen defining a true lumen diameter and the false lumen formed by a false lumen wall defining a false lumen diameter, the endoprosthesis having a deployed diameter and a collapsed diameter;
- and
- deploying the endoprosthesis to the deployed diameter such that the endoprosthesis extends along the true lumen and along at least a portion of the false lumen at a position where the defect is located in the aorta such that the endoprosthesis defines a flow bypass through a diseased portion of the aorta.
A method of assessing an ascending aorta of a patient, the method comprising:
- measuring at least one measurement of a transverse aortic diameter that is a sum of a diameter of a true lumen and diameter of a false lumen of the ascending aorta;
- selecting a deployed diameter of an endoluminal device to be compatible with any of the measured transverse aortic diameters;
- and
- implanting the endoluminal device within the aorta.
An implantable system configured to be implanted within an aorta of a patient, the implantable system comprising:
- an implantable medical device expandable from a collapsed diameter to a deployed diameter, wherein the deployed diameter is sized relative to a total diameter of the aorta including a true lumen diameter and a false lumen diameter;
- a first constraint configured to maintain the implantable medical device at the collapsed diameter;
- and
- a second constraint configured to maintain the implantable medical device at an intermediate diameter between the collapsed diameter and the deployed diameter.
