Abstract
A medical device is provided that includes a vessel-engaging member attached to a distal end of a delivery wire. The vessel-engaging member includes a plurality of rows, with each row having a plurality of struts arranged in an alternating pattern such that for each row, a first set of vertices is positioned on a proximal side, and a second set of vertices is positioned on a distal side. The vessel-engaging member further includes a plurality of single bridges positioned between adjacent rows, each of the bridges connecting a vertex of a first row with a corresponding vertex of an adjacent second row. The vessel-engaging member can also include a plurality of double bridges positioned between adjacent rows, each of the double bridges connecting a vertex of a first row with two adjacent vertices of an adjacent second row.
