rinsing device for retrograde blood flow occlusion. the present invention relates to a device and a method for establishing retrograde blood flow during recanalization of a vessel having a target block. while in a retracted state, an occlusion component is introduced distally intravascularly through the target block to its distal side. then, the occlusion component transitions to an expanded state having an enlarged diameter that forms a seal with an inner vessel wall, prohibiting anterograde blood flow beyond the expanded occlusion component. the retrograde blood flow is thus established in a region of the vessel connected to one end by the occlusion component and, at an opposite end, by the target block by dispensing a rinse fluid into the region of the vessel. refers to a device and method for establishing retrograde blood flow during recanalization of a vessel having a target block. while in a retracted state, an occlusion component is introduced distally intravascularly through the target block to its distal side. then, the occlusion component transitions to an expanded state having an enlarged diameter that forms a seal with an inner vessel wall, prohibiting anterograde blood flow beyond the expanded occlusion component. the retrograde blood flow is thus established in a region of the vessel connected to one end by the occlusion component and, at an opposite end, by the target block by dispensing a rinse fluid into the region of the vessel.dispositivo de enxágue para oclusão de fluxo sanguíneo retrógrado. a presente invenção refere-se a um dispositivo e um método para estabelecer o fluxo sanguíneo retrógrado durante a recanalização de um vaso tendo um bloqueio-alvo. enquanto em um estado retraído, um componente de oclusão é introduzido distalmente por via intravascular que atravessa o bloqueio-alvo até seu lado distal. então, o componente de oclusão faz a transição para um estado expandido tendo um diâmetro ampliado que forma uma vedação com uma parede interna
