Abstract:
1. An occlusion device adapted to be received within and to occlude a cavity defined by a body, the body comprising tissue forming a rim having a circumference and defining an opening extending into the cavity, said occlusion device comprising: a first laterally-expandable portion formed of at least one metal strand woven into at least one layer of a tubular fabric, and having opposed proximal and distal ends, the first portion being configured to be insertable into the cavity through the opening so as to be substantially disposed within the cavity upon lateral expansion thereof; a second laterally-expandable portion formed of at least one metal strand woven into at least one layer of a tubular fabric, the second portion having opposed proximal and distal ends and being configured to be insertable into the cavity distally to the first portion; a laterally-expandable connective element formed of at least one metal strand woven into at least one layer of a tubular fabric, the connective element being operably engaged with and tethering the distal end of the first portion to the second portion, and cooperable therewith to form a collapsible assembly extending along an insertion axis, wherein at least one of the distal end of the first portion and the proximal end of the second portion defines a concavity configured to receive at least a portion of the connective element; and a plurality of retention members operably engaged with at least one of the first and second portions and spaced apart about a laterally outward surface thereof, the retention members configured to be non-piercing with respect to the body defining the cavity and -adapted to engage the body, upon insertion of the collapsible assembly, in a collapsed state and with the second portion first inserted distally to the first portion, into the cavity along the insertion axis and subsequent lateral expansion of the first and second portions, so as to retain the assembly substantially within the cavity.
