Method and apparatus implementing and using techniques for body lumen closure, including use of an implantable medical closure device. The device includes a flexible strand (20) defining an arcuate form. The strand is deformable upon implantation from a large cross-section condition to a small cross-section condition and has at least two anchoring portions (30) disposed along the strand. The anchoring portions are configured to penetrate a wall of a body lumen such that when the strand is deformed to the small cross-section condition, the wall of the body lumen is disposed inwardly.
L'invention concerne un procédé et un dispositif de mise en oeuvre et d'utilisation de techniques de fermeture de lumière corporelle, y compris l'utilisation d'un dispositif de fermeture médical implantable. Ce dispositif comprend un brin souple (20) de forme arquée. A l'issue de l'implantation, ce brin se déforme en passant d'un état de coupe transversale importante à un état de coupe transversale réduite. Il comprend en outre deux parties de fixation (30). Ces parties de fixation sont configurées pour pénétrer dans une paroi de la lumière corporelle et l'ouvrir vers l'intérieur lorsque le brin se déforme et se retrouve dans l'état de coupe transversale réduite.
