Vascular stent with improved vessel wall apposition
First Claim
1. 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 pairs of adjacent rows, each of the single bridges connecting a single vertex of a first row of each pair of adjacent rows with a single vertex of a second row of each pair of adjacent rows; and
a plurality of double bridges positioned between the pairs of adjacent rows, each of the double bridges connecting a single vertex of the first row of each pair of adjacent rows with two vertices of the second row of each pair of adjacent rows, the two vertices of the second row being adjacent to each other, 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.

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.

20. A medical device for insertion into a vessel, comprising:
-
a frame 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 offset from the first set of vertices; a plurality of single bridges positioned between adjacent rows, each of the bridges connecting a single vertex of the second set of vertices of a first row with a single vertex of the first set of vertices of a second row; and a plurality of double bridges positioned between adjacent rows, each of the double bridges connecting a single vertex of the first row with two vertices of the second row, the two vertices of the second row being adjacent to each other, 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. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38)
