  • Vascular Stent for late endothelial progenitor cells
  • After ballooning angioplasty and stent implantation, fast reconstruction of a damaged endothelial layer, called
    ‘reendothelialization’, is one of necessary processes for successful medical treatment of myocardial infarction.
    The reendothelialization can be achieved by mobillization of circulating endothelial progenitor cells (EPCs) from the
    bone marrow. However, current stents including bare metal stents (BMS) and drug-eluting stents (DES) have several
    disadvantages for reendothelialization. The former has a poor surface to make EPCs adhere and latter have deterio
    rative effect on viability of endothelial cells. To accomplish the complete reendothelialization, we fabricated two types
    of advanced stent which have functions of delivery or recruitments of EPCs.

  • Nanocoupling
  • Non-vascular stents on the contrary are used for clearing the occlusion or strictures in the non-vascular conduits, for
    example in the oesophagus, biliary duct, trachea, bronchi, sinus cavities, ureters, and urethra.
