The invention relates to a medical self-expandable occlusion device for treating heart defects of a patient, especially for closing abnormal holes in the tissue. The occlusion device (1) can be inserted into the body of a patient by means of a catheter system in a minimally invasive manner. The occlusion device (1) consists of an interlaced structure (1) of thin threads, the interlaced structure (10) having a first shape during insertion of the occlusion device into the body of the patient, which shape can be previously determined, and a second shape in the implanted position of the occlusion device, which shape can be previously determined, the occlusion device in the first shape of the interlaced structure (10) being in a folded condition and in the second shape of the interlaced structure (10) being in an expanded condition. The aim of the invention is to provide an occlusion device which can be implanted in as gentle a manner possible for the patient. For this purpose, the threads of the interlaced structure (10) consist of a shape memory polymer composition so that the interlaced structure (10) is deformed under the effect of an external stimulus from a temporary shape to a permanent shape, the temporary shape being the first shape of the interlaced structure (10) and the permanent shape being the second shape of the interlaced structure (10).

L'invention concerne un instrument d'occlusion médical auto-expansible conçu pour traiter des défauts affectant le coeur d'un patient, et servant en particulier à fermer des ouvertures tissulaires anormales. Selon l'invention, l'instrument d'occlusion (1) peut être introduit dans le corps d'un patient avec effraction minimale au moyen d'un système de cathéter. L'instrument d'occlusion (1) est constitué d'un treillis (10) de fils minces. Lors de l'introduction de l'instrument d'occlusion dans le corps du patient, le treillis (10) présente une première forme prédéfinissable, et une fois l'instrument d'occlusion implanté, ledit treillis présente une deuxième forme prédéterminable. Lorsque le treillis (10) présente la première forme, l'instrument d'occlusion est plié, et lorsque le treillis (10) présente la deuxième forme, l'instrument d'occlusion est déployé. Pour que l'instrument d'occlusion puisse être implanté d'une manière particulièrement inoffensive pour le patient, les fils du treillis (10) sont constitués d'une composition de polymère à mémoire de forme, de manière que le treillis (10) passe d'une forme temporaire à une forme permanente sous l'effet d'un stimulus externe, la forme temporaire correspondant à la première forme du treillis (10), et la forme permanente à la deuxième forme du treillis (10).
