Abstract

a invenção fornece um dispositivo de aterectomia rotacional que tem, em várias modalidades, um eixo de transmissão flexível, alongada e giratória com um sistema de cabeças friccionais excêntricas afixadas à mesma. pelo menos parte das cabeças friccionais ampliadas excêntricas no sistema tem uma superfície que remove tecido - tipicamente uma superfície abrasiva. em certas modalidades, as cabeças friccionais podem ser pelo menos parcialmente ocas. preferencialmente, as cabeças friccionais ampliadas excêntricas têm centros de massa espaçados radialmente do eixo rotacional do eixo de transmissão, o que facilita a habilidade do sistema de cabeças friccionais excêntricas de trabalhar conjuntamente para abrir a lesão estenótica a um diâmetro substancialmente maior que o diâmetro de repouso externo das cabeças friccionais ampliadas quando operado em velocidades altas. portanto, certas modalidades compreendem um sistema que tem centros de massa desequilibrados não apenas para estimular diâmetros rotacionais maiores, mas também que estão dispostos de uma maneira em que um efeito de trado removedor de resíduos ocorra. alternativamente, outras modalidades podem compreender sistemas que têm cabeças friccionais com centros de massa equilibrados.
