ABSTRACT:
An expandable tubular reinforcing member of the invention is used for a body lumen, such as a blood vessel for reinforcement. The reinforcing member is formed of a tortuous section having a plurality of laterally extending elongated members, and a plurality of vertically extending end members situated between two adjacent elongated members for connecting the same. The tortuous section is arranged diagonally to form a cylindrical shape with a first diameter extending in a spiral form. The elongated members generally extend parallel to a central axis of the cylindrical shape. A plurality of joint members is situated between two end members arranged in the cylindrical shape to keep the shape. When a radial force is applied from an inside of the reinforcing member, the elongated members are bent relative to the end members to thereby allow the tubular reinforcing member to have a second diameter larger than the first diameter to thereby hold the body lumen.
