Abstract
valvulótomos autodimensional, auto-centrante, over-the-wire, e método para realizar um procedimento de valvulotomia. a presente invenção refere-se a valvulótomos autodimensionáveis, autocentrantes over-the-wire suficientemente projetados para cortar válvulas através de uma ampla faixa de diâmetros de veia e ajustar ao diâmetro interno de uma veia à medida que o valvulótomo está sendo puxado através do vaso. em uma modalidade, um valvulótomo over-the-wire (100) inclui um cateter (14) tendo uma extremidade proximal, uma extremidade distal e um eixo longitudinal entre as mesmas, em que uma primeira porção (168) de uma pluralidade de ferramentas de corte (160) engata no cateter (140) na extremidade distal, e em que um mecanismo de acionamento (180) engata no cateter (140) na extremidade proximal; um retentor (132) para blindar temporariamente uma segunda porção (162) da pluralidade de ferramentas de corte (160), em que a segunda porção (162) inclui lâminas de corte (164); e uma bainha (170) que se move de forma deslizante sobre a pluralidade de lâminas de corte (164), em que o cateter (140) e o retentor (132) têm diâmetros internos configurados para passar sobre um fio-guia.
