Patent ID: 8267986

Claim:
A method, of treating an aneurysm in a suprathoracic vessel of a patient, comprising: expanding, in the suprathoracic vessel having an aneurysm, a first stent having a first stent proximal end and a first stent distal end, such that the first stent extends from a first location, proximal to the aneurysm, to a second location, distal to the aneurysm; applying an axially compressive force to a first portion of the first stent, the first portion overlying the aneurysm, whereby the first portion transitions from a first porosity to a second porosity, less than the first porosity, while (i) the first portion maintains a substantially similar cross-sectional dimension and (ii) wherein movement of a second portion of the first stent, distal to the first portion, is impeded by a frictional force applied by the first stent against a vessel wall distal to the aneurysm; expanding, after expanding the first stent, a second stent within the first stent, the second stent having a second stent proximal end and a second stent distal end, such that when the second stent is expanded and engages the first stent, the second stent is axially positioned substantially adjacent to the aneurysm, the second stent proximal end is positioned distal to the first stent proximal end, and the second stent distal end is positioned proximal to the first stent distal end, thereby impeding blood flow from the suprathoracic vessel into the aneurysm.
