Claim Text:
1. A vascular device, comprising: a mesh structure formed of a plurality of filaments, the structure having (i) a first, collapsed configuration, (ii) a second, expanded configuration, and (iii) a density of the plurality of filaments; and a plurality of elastic members disposed along a region of the structure, the region having a proximal end and a distal end, wherein a proximalmost end of each of the elastic members is attached to the proximal end of the region and a distalmost end of each of the elastic members is attached to the distal end of the region, and wherein the elastic members (i) are configured to increase the density within the region by drawing the proximal and distal ends of the region toward each other when the structure is in the second configuration, (ii) are configured to decrease an axial length of the region without substantially changing a cross-sectional dimension of the structure when the structure is in the second configuration, and (iii) have a first length in the first configuration and a second length in the second configuration, wherein the second length is shorter than the first length, wherein each of the elastic members comprises a portion and a terminal end, wherein the portion (a) wraps around one of the filaments on a radially inner side and a radially outer side of the one of the filaments, and (b) overlaps and is attached to the terminal end.
