Abstract
"PROCESSO DE REVESTIMENTO DE STENTS PARA IMPLANTE INTRACORONáRIO COM BLENDA POLIMéRICA HDROFóBICA DOADORA DE óXIDO NìTRICO". Novo processo para o revestimento de stents com a blenda polimérica de poliéster polinitrosado/PMMA, com o objetivo de se obter um stent revestido com um polímero hidrofóbico doador de NO, para aplicações em angioplastia, o qual tem a finalidade de inibir a reestenose, atendendo a um grande interesse recente no desenvolvimento de materiais poliméricos atóxicos, capazes de liberar gradualmente NO, para aplicações biomédicas, de forma a previr a ativação e a adesão de plaquetas, reduzindo a proliferação das células musculares lisas, estimulando a proliferação das células endoteliais e a gênese de novos vasos e promovendo a vasodilatação dos vasos sanguíneos, uma vez que a liberação local de NO a partir da superfície de stents revestidos tem grande potencial na prevenção da trombose, podendo também reduzir a reestenose após a angioplastia.
