Abstract

dispositivos híbridos de aterectomia. são fornecidos dispositivos de aterectomia de pressionamento lateral, de condução autônoma e telescópicos, cada um tendo uma bainha flexível, um cortador com caneluras helicoidais e um conjunto de acionamento. o conjunto de acionamento pode ter um eixo acionador flexível rotativamente translacional com o lúmen da bainha flexível, uma bomba de deslocamento positivo para transportar tecido cortado e um eixo acionador flexível que pode ser mais longo que a bainha flexível para um alongamento telescópico reversível do conjunto de acionamento do lúmen da bainha flexível. a bomba de deslocamento positivo pode ser uma bomba de parafuso que tem uma porção de parafuso de acionamento exposta para contato com um lúmen vascular para uma condução autônoma do dispositivo através do lúmen vascular. um elemento de pressionamento lateral reversivelmente expansível pode ser incluído na extremidade distal da bainha flexível para um pressionamento lateral do cortador. são fornecidos cabeças cortantes aprimoradas e métodos de fabricação delas para cortar uma combinação de placa mole e dura.
