Abstract

"CATETER COM PONTA RESISTENTE à OCLUSãO". A presente invenção refere-se a um cateter que inclui um corpo tubular alongado que se estende para uma extremidade distal. O corpo tubular tem um primeiro e um segundo lúmen com um septo disposto entre eles. O corpo tubular inclui uma primeira parede que define o primeiro lúmen e uma segunda parede que define o segundo lúmen. Uma porção do septo se estende no sentido distal além do primeiro lúmen e do segundo lúmen. A primeira parede inclui uma primeira extensão de parede que se estende no sentido distal além do primeiro lúmen e é separada da porção do septo. A primeira extensão de parede define uma superfície cóncava virada para a porção do septo. Alternativamente, o septo tem uma extensão de septo que se estende no sentido distal além do primeiro lúmen e do segundo lúmen. Na modalidade alternada, a extensão do septo define uma primeira superfície planar e uma segunda superfície planar oposta.
