EXPANSIBLE SPLIT STENT Russian patent published in 2002 - IPC

FIELD: medicine, in particular surgery. SUBSTANCE: the stent has proximal and distal ends connected to each other, and a tube wall positioned between the proximal and distal ends connected to each other, and a tube wall positioned between the proximal and distal ends interconnected integrally in the points of their intersection, the great number of intersecting members determines the first repeating pattern (A), which in the two- dimensional form and in the non-expanded state of the stent is a polygon, having a pair of side walls, essentially parallel to the longitudinal axis, the first concave wall and the second convex wall connecting the side walls. The stent also has t least two peripherally positioned rings of the first repeating pattern A. The stent is expansible from the first compressed position, in which the tube wall is made without a bend in the longitudinal axis, to the second expanded position at application of force radially directed outside to the stent. At least both, the first concave and second convex walls, have a plane top in the form of a segment perpendicular to the longitudinal axis. EFFECT: facilitated procedure of stent installation. 9 cl, 7 dwg
