Abstract

1. Протез, содержащий спиральный корпус, имеющий несколько витков, содержащих бистабильные ячейки, соединенные перемычками, причем каждая из бистабильных ячеек содержит тонкий стержень, включающий первый и второй концы, соединенные с толстым стержнем, причем тонкий стержень выполнен с возможностью перехода только между устойчивой полностью сжатой конфигурацией и устойчивой полностью раздвинутой конфигурацией. ! 2. Протез по п.1, дополнительно содержащий по меньшей мере один оконечной виток, включающий дополнительные единичные ячейки, которые задают кольцевую конструкцию, когда протез развернут. ! 3. Протез по п.2, в котором по меньшей мере некоторые из дополнительных единичных ячеек представляют собой бистабильные ячейки. ! 4. Протез по п.1, в котором тонкий стержень имеет первую толщину, толстый стержень имеет вторую толщину, а отношение первой толщины ко второй толщине составляет от 1:2 до 1:5. ! 5. Протез по п.1, в котором тонкий стержень и толстый стержень удлинены в направлении, параллельном продольной оси спирального корпуса. ! 6. Протез по п.1, в котором первый конец тонкого стержня соединен с толстым стержнем на дистальном конце единичной ячейки, а второй конец тонкого стержня соединен с толстым стержнем на проксимальном конце единичной ячейки, причем, когда протез развернут, проксимальные концы единичных ячеек одного витка спирального корпуса прилегают к дистальным концам единичных ячеек смежного витка спирального корпуса. ! 7. Протез по п.6, в котором шаг спирального корпуса выбран таким, что, когда протез развернут, между проксимальными концами единичных ячеек одного витка спирального корпуса и дистальным
