ABSTRACT:
A self-expanding medical occlusion device treats a heart defect in a patient and is inserted into the body in minimally invasive fashion using a catheter system, and includes a braiding of thin threads which exhibits a first preliminarily definable shape as the occlusion device is being inserted into the patient's body and a second preliminarily definable shape in the implanted state, whereby the occlusion device is in a collapsed state in the first shape of the braiding and in an expanded state in the second shape of the braiding. The threads of braiding are composed of a shape memory polymer composite such that braiding deforms from a temporary shape to a permanent shape in consequence of an external stimulus, whereby the temporary shape is given in a first profile form of the braiding and the permanent shape is given in a second profile form of the braiding.
