Claim 11
Dependent Claim
25 words
The method of claim 9 , wherein: the providing step is carried out with the cover being wrapped around the expandable element without overlapping folds.
Claim 12
Independent Claim
123 words
A method of treating an aneurysm, comprising the steps of: providing a cover which is positioned around an expandable element in a collapsed position, the cover being covered by a sheath, the cover also having an extension which is movable between a retracted position and an expanded position, the extension extending away from the cover in the expanded position; advancing the cover to an aneurysm in a patient with the cover in the collapsed position; withdrawing the sheath to expose the cover; expanding the expandable member thereby expanding the cover, the cover expanding to an expanded condition, the cover being positioned over a neck of the aneurysm while the extension is in the expanded position and passes into the neck of the aneurysm.
Claim 13
Independent Claim
123 words
A method of treating an aneurysm, comprising the steps of: providing a cover which is positioned around an expandable element in a collapsed position, the cover being covered by a sheath, the cover also having an extension which is movable between a retracted position and an expanded position, the extension extending away from the cover in the expanded position; advancing the cover to an aneurysm in a patient with the cover in the collapsed position; withdrawing the sheath to expose the cover; expanding the expandable member thereby expanding the cover, the cover expanding to an expanded condition, the cover being positioned over a neck of the aneurysm while the extension is in the expanded position and passes into the neck of the aneurysm.
