Abstract:
1. A collapsible medical device comprising an outer fabric layer surrounding at least one inner fabric layer, each of the outer and inner fabric layers comprising proximal and distal ends and a central axis extending therebetween, each of the outer and inner fabric layers comprising a plurality of braided metal strands having proximal and distal ends, the outer and inner fabric layers having an expanded preset configuration comprising proximal and distal geometrically shaped end sections coaxial with a central geometrically shaped part therebetween, the proximal and distal geometrically shaped end sections and the geometrically shaped central part being disposed along the central axis and the proximal and distal ends of the outer and inner fabric layers corresponding to the proximal and distal ends of the plurality of braided metal strands, each of the proximal and distal geometrically shaped end sections are coupled to the central geometrically shaped part by a connector having a cross-sectional area smaller than the cross-sectional area of each of the proximal and distal geometrically shaped end sections and the central geometrically shaped part such that each of the proximal and distal geometrically shaped end sections and the central geometrically shaped part are configured to articulate about a respective connector of the connectors.
