Abstract

"NúCLEO DE DISCO ESPINHAL PROTéTICO PERCUTâNEO EPROCESSO DE FABRICAçãO". Um núcleo de disco espinhalprotético em forma de cápsula (20) para a implantação em umespaço intradiscal humano (60), feito de uma jaqueta de apertosubstancialmente inelástica (24), que circunda um núcleo depolímero amorfo (22). A jaqueta de aperto (24) tem um volumemáximo geralmente fixo e define uma altura. O núcleo de polímeroamorfo (22) enche um volume inicial da jaqueta de aperto (24) edesenvolve uma pressão interna. Em resposta à pressão interna, ajaqueta de aperto (24) passa para o volume máximo, aumentandosubstancialmente em altura.
