Abstract:
1. A medical device, comprising: a delivery wire having a proximal end and a distal end; a connection mechanism; and a vessel-engaging member attached to the distal end of the delivery wire via the connection mechanism, 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 bridges positioned between each adjacent row, each of the bridges connecting a vertex of a first row with a vertex of a second row, the vertex of the first row lying substantially along a line parallel to a longitudinal axis of the vessel-engaging member and the vertex of the second row lying outside the line, each of the bridges extending continuously distally from the vertex of the first row to the vertex of the second row, a cross-sectional width of each of the plurality of bridges being less than a cross-sectional width of each of the struts to which that bridge connects; and first and second tapered sections coupled to the connection mechanism, each of the tapered sections projecting from a proximal row and tapering in a direction from the proximal row toward the connection mechanism, each of the tapered sections having a length measured along the longitudinal axis; wherein the length of the first tapered section is less than the length of the second tapered section.
