Abstract:
A stent to be used in angioplastic procedures for the treatment of lesions in or about the bifurcated areas of vessels, comprising:A) a parabolically extending support member having a plurality of transverse through openings at predetermined distances from each other and further including first and second ends;B) a plurality of hyperbolically extending transverse members rotatably mounted to said through openings and further including third and fourth ends and a central portion in between so that, in the collapsed configuration, said first and second ends extend substantially parallel to each other with a relatively small separation in between and said third ends are kept at a parallel and abutting relationship with respect to each other thereby defining a first substantially cylindrical secondary branch and said fourth ends being kept at a parallel and abutting relationship with respect to each other defining a second substantially cylindrical secondary branch and, in the expanded configuration, said first and said second ends being separated from each other a predetermined distance with the central portions of said plurality of hyperbolically extending transverse members defining a main branch.
