This invention is an occlusion device (10) for use in a body lumen such as the left atrial appendage (31). The occlusion device includes an occlusion member (11), and may also include a stabilizing member (12). The stabilizing member inhibits compression of the left atrial appendage, facilitating tissue ingrowth onto the occlusion member. The method of making the device includes forming a plurality of slots in a tube, the slots creating radially outwardly biased longitudinal elements (228). A membrane barrier (15) is then attached to the elements.

L'invention concerne un dispositif d'occlusion (10) destiné à une cavité corporelle telle que l'auricule cardiaque gauche (31). Ce dispositif d'occlusion comporte un élément d'occlusion (11) et peut également comporter un élément de stabilisation (12). Cet élément de stabilisation (12) inhibe la compression de l'auricule cardiaque gauche, facilitant ainsi l'interposition de tissu sur l'élément d'occlusion. Le procédé de fabrication de ce dispositif consiste à pratiquer sur un tube une pluralité de fentes, ce qui a pour effet de créer des éléments longitudinaux (228) orientés dans le sens radial vers l'extérieur. On fixe ensuite une barrière membranaire (15) à ces éléments.
