Intravasal dilatation of arteries using elastic nitinol stents

Intravasion stent, a dilatator made of TH&10 nikelid&titanium (NiTi) in experimental study carried out on the infrarenal aort of 22 dogs, showed its biological and biomechanical compatibility, noninvasiveness and elasticity. At check time after the surgery no thrombosis, hyperptoproliferative reaction of neointima, cicatricial deformity of vessel, migration and stent dislocation were revealed. Macro& and microanalysis displayed that formation of neointima starts by the first month and ends up with full endotelization of stent by the 6th months.
