Abstract
A vascular device is provided that includes a mesh structure formed of a plurality of spaced members. The structure has (i) a first, collapsed configuration, (ii) a second, expanded configuration, and (iii) a density of the plurality of members. The vascular device further includes an elastic member disposed along a region of the structure, the region having a proximal end and a distal end. The elastic member is configured to increase the density within the region by drawing at least one of the proximal and distal ends of the region toward the other of the proximal and distal ends when the structure is in the second configuration.

A vascular device, comprising:
- a mesh structure formed of a plurality of spaced members, the structure having (i) a first, collapsed configuration, (ii) a second, expanded configuration, and (iii) a density of the plurality of members;
- and
- an elastic film disposed along a region of the structure, the region having a proximal end and a distal end, wherein the elastic film is configured to increase the density within the region by drawing at least one of the proximal and distal ends of the region toward the other of the proximal and distal ends when the structure is in the second configuration.
A method for treating an aneurysm comprising:
- positioning a vascular device in a vessel at an ostium of the aneurysm, wherein the device comprises:
- a mesh structure formed of a plurality of spaced members, the structure having a density of the plurality of members;
- and
- an elastic film along a region of the structure, the region having a proximal end and a distal end;
- expanding the device from a collapsed configuration to an expanded configuration by proximally withdrawing, relative to the device, an outer sheath surrounding the device;
- increasing the density within the region by drawing, with the elastic film, at least one of the proximal and distal ends of the region toward the other of the proximal and distal ends as the structure expands to the expanded configuration.
