Device for occluding a hole in a body wall and a unit for inserting said device

摘要

The device includes a solid disk ( 1 ) whose diameter is larger than the diameter of a hole ( 2 ) to be treated and which is formed by a peripheral deformable thread ( 6 ) made of a shape memory material and a flexible membrane ( 6 ) which is made of biocompatible material and connected to the thread; and at least an attachment ( 15 ) separated from the disk ( 1 ) which makes it possible to fix the disk ( 1 ) to the body wall. Each attachment ( 15 ) is provided with an area ( 16 ) for linking to the disk and an area ( 16 ) for linking to the body wall ( 3 ) and is embodied such that it is deformable and can be introduced into a hollow needle ( 28 ).
