A medical device, comprising: a delivery wire having a proximal end and a distal end; and a vessel-engaging member attached to the distal end of the delivery wire, the vessel-engaging member comprising: a plurality of rows, 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; 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; and 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, wherein each of the plurality of double bridges is arranged generally along a line progressing laterally at an angle with respect to a longitudinal axis of the member; characterized in that the single bridges positioned between a first row and an adjacent second row alternate laterally with the double bridges positioned between said adjacent rows. a delivery wire having a proximal end and a distal end; and a vessel-engaging member attached to the distal end of the delivery wire, the vessel-engaging member comprising: a plurality of rows, 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; 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; and 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, wherein each of the plurality of double bridges is arranged generally along a line progressing laterally at an angle with respect to a longitudinal axis of the member; characterized in that the single bridges positioned between a first row and an adjacent second row alternate laterally with the double bridges positioned between said adjacent rows. a plurality of rows, 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; 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; and 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, wherein each of the plurality of double bridges is arranged generally along a line progressing laterally at an angle with respect to a longitudinal axis of the member; characterized in that the single bridges positioned between a first row and an adjacent second row alternate laterally with the double bridges positioned between said adjacent rows.
