Abstract

Translated fromPortuguese

"DISPOSITIVO PROTéTICO TUBULAR CILìNDRICO; E DISPOSITIVO PROTéTICO COM ENVOLTóRIO DE CAPA BIOLóGICA PARA LIBERAçãO DE FáRMACOS; E RESPECTIVO SISTEMA DE DELIVRAMENTO INTRALUMINAL". Descreve-se um dispositivo protético tipo estentor 50 padronizado, implantável no corpo humano, com delivramento intraluminal, expansível por catéter-balão 25, associado a envoltório de capa biológica para liberação de fármacos 32, com a função de liberação lenta e controlada de drogas antiaterogênicas, armazenadas em microcápsulas 36 dispersas no interior de bolsas retangulares longitudinais 11 constituintes deste tipo de envoltório. Tais dispositivos são normalmente utilizados na correção de estenoses ou oclusões da parede vascular ou ductos corporais, objetivando manter a patência dos mesmos por mais prolongado período de tempo e anular totalmente a complicação tardia da reestenose. O dispositivo protético tipo estentor 50 possui estrutura espacial disposta em anéis 45 formados da união de hastes transversais 29 em forma de "s", variando em quantidade de acordo com o diâmetro e comprimento de cada prótese, coaptadas por ligamentos longitudinais 12, dispostos no sentido axial deste objeto de invenção e interconectados com esferas de componentes químicos radioativos 10. Possui sistema de acoplamento intraluminal adjunto, constituído por corda-guia convencional 17 para delivramento do envoltório de capa biológica para liberação de fármacos 32 e catéter-balão 25 com dispositivo protético tipo estentor pré-montado sobre o balão desinsuflado 26."Cylindrical Tubular Prosthetic Device; and Prosthetic Device with Biological Cover for Drug Release; and the respective Intraluminal Delay System". A standard implantable prosthetic device 50, implantable in the human body, with balloon catheter-expandable intraluminal folding 25, associated with a drug-release biological wrapper 32, with the function of slow and controlled release of antiatherogenic drugs is described. stored in microcapsules 36 dispersed within longitudinal rectangular pockets 11 constituting this type of wrapper. Such devices are commonly used to correct stenoses or occlusions of the vascular wall or body ducts, aiming to maintain their patency for a longer period of time and totally nullify the late complication of restenosis. The stent type prosthetic device 50 has a spatial structure arranged in rings 45 formed of the union of transverse rods 29 in the form of "s", varying in quantity according to the diameter and length of each prosthesis, co-opted by longitudinal ligaments 12, arranged in the direction of this object of the invention and interconnected with spheres of radioactive chemical components 10. It has an adjunct intraluminal coupling system, consisting of a conventional guidewire 17 for the release of the drug-free biological envelope wrap 32 and a balloon catheter 25 with a prosthetic device type pre-assembled stretcher over deflated balloon 26.
