Patent ID: 7695509

Claim:
A micro-porous mesh structure for supporting a wall of a body passage at a bifurcation, comprising: a first generally tubular body, the first generally tubular body comprising a shape memory alloy, the first generally tubular body having a contracted condition for facilitating delivery into the body passage, and an enlarged condition for engaging the wall of the body passage at the bifurcation, the first tubular body being biased to its enlarged condition, the first tubular body having a plurality of first openings defining a micro-porous mesh pattern therein; a second generally tubular body, the second generally tubular body comprising a shape memory alloy, the second generally tubular body having a contracted condition for facilitating delivery into the body passage at the bifurcation, and an enlarged condition for engaging the wall of the body passage at the bifurcation, the second generally tubular body being biased to its enlarged condition, the second generally tubular body having a plurality of second openings defining a micro-porous mesh pattern therein, the second generally tubular body being longitudinal offset from the first generally tubular body; and a support element, the support element providing structural support for holding the generally tubular bodies against the wall of the body passage at the bifurcation.
