Occlusive implant system

An occlusive implant system, comprising:

• an occlusive implant comprising an expandable framework configured to shift between a collapsed configuration and a deployed configuration;
• and
• an occlusive covering secured to the expandable framework;
• wherein the expandable framework comprises:
• a plurality of interconnected struts extending between a proximal collar and a distal hub;
• a proximal hub secured within the proximal collar;
• a perimeter shoulder portion spaced apart radially outward from the proximal hub in the deployed configuration;
• and
• a proximal face extending between the proximal hub and the perimeter shoulder portion;
• wherein the occlusive covering extends from the proximal hub across the proximal face of the expandable framework and over the perimeter shoulder portion;
• wherein the occlusive covering is mechanically secured against an outer surface of the proximal collar.

• a proximal face extending between the proximal hub and the perimeter shoulder portion, wherein the proximal face of the expandable framework includes a distally recessed portion surrounding the proximal collar and a proximal surface disposed radially outward of the distally recessed portion and proximal of the distally recessed portion in the deployed configuration;
• wherein the occlusive covering extends radially outward from the proximal collar across the proximal face of the expandable framework;
• wherein the occlusive covering is mechanically secured to the proximal collar by a ring member;
• wherein in the deployed configuration, the ring member is disposed distal of the proximal surface.
