Abstract
(EN)
Apparatus (720) is provided for treating a vascular malformation, including an orifice section (430), an occlusion section (432), and a connecting section (434). When the apparatus (720) is unconstrained, the orifice and occlusion sections (430, 432) are shaped so as to define orifice- section and occlusion-section curves (440, 450) that wind around non-coaxial orifice-section and occlusion-section central axes (442, 452), respectively, at changing distances from the axes (442, 452). The orifice- section curve (440) defines an orifice- section central opening (462). A projection of the occlusion- section curve (450) occludes at least 25% of a orifice-section-central-opening cross- sectional area of an orifice- section central opening (462); the projection of the occlusion- section curve (450) is in a direction along the orifice-section central axis (442), onto an orifice-section plane perpendicular to the orifice-section central axis (442). Other embodiments are also described.

L'invention concerne un appareil (720) destiné au traitement d'une malformation vasculaire, comprenant une section d'orifice (430), une section d'occlusion (432) et une section de liaison (434). Lorsque l'appareil (720) est non contraint, les sections d'orifice et d'occlusion (430, 432) sont façonnées de manière à délimiter des courbes de section d'orifice et de section d'occlusion (440, 450) qui s'enroulent autour d'axes centraux de section d'orifice et de section d'occlusion (442, 452) non coaxiaux, respectivement, à des distances variables des axes (442, 452). La courbe de section d'orifice (440) délimite une ouverture centrale de section d'orifice (462). Une projection de la courbe de section d'occlusion (450) obture au moins 25 % d'une superficie de section transversale d'ouverture centrale de section d'orifice d'une ouverture centrale de section d'orifice (462) ; la projection de la courbe de section d'occlusion (450) est dans une direction le long de l'axe central de la section d'orifice (442), sur un plan de section d'orifice perpendiculaire à l'axe central de section d'orifice (442). L'invention décrit également d'autres modes de réalisation.
