  • Stent
    Patent number: 10524940
    Abstract: Provided is a stent having a novel structure, the stem simultaneously having both the stability of shape against the action of external force, such as compression force, tensile force, or torsional force, and high flexibility in the direction of twisting of the stem. Connection groups are provided at three or more positions set at circumferentially equally-spaced intervals, the connection groups each including connection sections which are disposed circumferentially close to each other between axially adjacent tubular divided bodies. The connection groups on both sides axially of each of the tubular divided bodies are provided at positions circumferentially offset from each other while at least one turning portion is present between the connection groups.
    Type: Grant

  • VASCULAR RESTENOSIS PREVENTING AGENT AND IMPLANTABLE INTRAVASCULAR DEVICE COATED THEREWITH
    Publication number: 20100003302
    Abstract: A drug for preventing vascular restenosis comprises a compound that inactivates ?1-protease inhibitor and ?2-macroglobulin as active constituents, which are associated with occurrence of vascular restenosis after coronary artery intervention. Preferably, the drug is coated on a surface of an implantable intravascular device and locally administered to the affected area by application of the implantable intravascular device to a narrowed area.
