Abstract

1. Саморасширяющееся устройство, в частности имплантат, для закрывания отверстий дефектов в теле человека или животного, которое имеет в первом состоянии форму вытянутой трубки (2) с шлицованными сегментами и принимает во втором состоянии укороченную форму, которая задает по меньшей мере одну открытую или, по существу, закрытую полую структуру (3) с большим поперечным размером, при этом шлицованные сегменты трубки (2) образуют отдельные перемычки (16), каждая из которых соединена с соседними перемычками (16), так что во втором состоянии возникает сетчатая общая структура. ! 2. Устройство по п.1, отличающееся тем, что проходящие в первом состоянии наклонно параллельные перемычки приводят к уменьшению напряжений и/или самоцентрированию. ! 3. Устройство по п.2, отличающееся тем, что предусмотрены две полые структуры (3) в виде проксимального экрана (5) и дистального экрана (6). ! 4. Устройство по любому из пп.1-3, отличающееся тем, что оно образовано из соединенных перемычек (16) из отдельных проволок, нескольких проволок или многожильных гибких проволок, которые сведены вместе на одном или обоих концах в виде кольца или трубки. ! 5. Устройство по п.4, отличающееся тем, что перемычки (16) состоят из скрученных и/или сплетенных нескольких проволок или нескольких многожильных гибких проволок. ! 6. Устройство по п.5, отличающееся тем, что оно имеет вид плетения или ткани. ! 7. Устройство по п.4, отличающееся тем, что на перемычках (16) расположены проушины (24) и/или перемычки (16) соединены через проушины (24). ! 8. Устройство по любому из пп.1-3, отличающееся тем, что устройство (1) образовано с соединенными перемычками (16) из трубки с помощью разрезания ла
