Интравазальная дилатация артерий с применением эластичных стентов из нитинола

Intravasion stent, a dilatator made of THa10 nikelidatitanium (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. Macroa and microanalysis displayed that formation of neointima starts by the first month and ends up with full endotelization of stent by the 6th months.
