Abstract
An occlusion device for occluding a cavity defined by a body is provided, and includes first and second laterally-expandable portions each formed of a woven tubular fabric and having opposed proximal and distal ends. The first portion is insertable into the cavity so as to be substantially disposed therein upon lateral expansion thereof. A connective element tethers the distal end of the first portion and the second portion, and is cooperable therewith to form a collapsible assembly extending along an insertion axis. Retention members, operably engaged with each of the first and second portions and spaced apart about a laterally outward surface thereof, are adapted to engage the body, after insertion of the collapsed assembly, second portion-first, into the cavity, and subsequent lateral expansion of the first and second portions, so as to retain the assembly substantially within the cavity. An associated deployment method is also provided.
