1. A method for manufacturing a vascular device, comprising:
- disposing a vascular device over an expanding member, the vascular device comprising a body having a substantially uniform porosity that is adapted to change by adjusting an axial length of the body; and
adhering a portion of the body to the expanding member such that upon radial expansion of the expanding member, adherence between the body portion and the expanding member reduces a porosity of the body within the body portion more than the expanding member reduces a porosity of the body outside the body portion by axially shortening the body portion with the expanding member.

Abstract
A method for manufacturing a vascular device that includes disposing a vascular device over an expanding member. The device includes a body having a substantially uniform porosity that is adapted to change by adjusting an axial length of the body. The method also includes adhering a portion of the body to the expanding member such that upon radial expansion of the expanding member, adherence between the body portion and the expanding member reduces a porosity of the body within the body portion more than the body porosity is reduced outside the portion.

8. A method for manufacturing a vascular device, comprising:
-
aligning a region of a vascular device with an area of an expanding member, the vascular device having a substantially uniform porosity that is altered by adjustment of an axial length of the vascular device; and adhering the region of the vascular device to the area of the expanding member such that upon radial expansion of the expanding member, adherence between the vascular device and the expanding member reduces a porosity of the region more than the adherence reduces a porosity outside the region by axially shortening the region with the expanding member. - View Dependent Claims (9, 10, 11, 12, 13)

14. A method for treating an aneurysm, the method comprising:
-
positioning a vascular device in a vessel at an ostium of the aneurysm, the vascular device comprising a body having a substantially uniform porosity that is adapted to change by adjusting an axial length of the body; inflating an expanding member positioned within a central lumen of the body; and reducing a porosity of the body within a body region more than a porosity of the body is reduced outside the body region as the body is radially expanded, by engaging the body with the expanding member and axially shortening the body region with the expanding member. - View Dependent Claims (15, 16, 17, 18, 19, 20)

21. A method for treating an aneurysm, the method comprising:
-
positioning a vascular device in a vessel at an ostium of the aneurysm, the vascular device having a porosity that is altered by adjustment of an axial length of the vascular device; expanding an expanding member positioned within a lumen of the vascular device; and reducing a porosity of the vascular device within a region more than a porosity of the vascular device is reduced outside the region by axially shortening the region with the expanding member. - View Dependent Claims (22, 23, 24, 25, 26)
