BARBED STENT VASCULAR OCCLUSION DEVICE
First Claim
1. A vascular occlusion device for occluding a body cavity defined by cavity walls, the device comprising:
- a tubular scaffold extending from a proximal end to a distal end and defining a device lumen therethrough, the scaffold being formed from a plurality of interconnected and articulated members configured to self-expand into an open configuration, a plurality of barbs extend from the articulated members with each barb including an anchoring end, the anchoring end being disposed radially outward from the scaffold in the open configuration and adapted to embed into the cavity walls; and
a radially expandable substance being disposed within the device lumen and attached to at least one of the articulated members, the substance being configured to promote body tissue growth within the body cavity to occlude the body cavity.

Abstract
A vascular occlusion device for occluding a body cavity. The device includes a tubular scaffold extending from a proximal end to a distal end. The scaffold is formed from a plurality of interconnected and articulated members configured to self-expand into an open configuration. A plurality of barbs extend from the articulated members, each barb including an anchoring end. The anchoring end is disposed radially outward from the scaffold in the open configuration and adapted to embed into the cavity walls. A radially expandable substance is disposed within a device lumen. The substance is configured to promote body tissue growth within the body cavity to occlude the body cavity. In one example, the body cavity includes a patent foramen ovale.

14. A vascular occlusion assembly for occluding a body cavity defined by cavity walls, the assembly comprising:
-
a delivery apparatus including an outer sheath having a proximal part extending to a distal part and defining a sheath lumen therein, an inner elongate element being disposed within the sheath lumen and having a proximal segment extending to a distal segment, the outer sheath being configured to translate axially relative to the inner element;
an occlusion device being disposed within the sheath lumen and engaging the distal segment of the inner element;the occlusion device comprising a tubular scaffold extending from a proximal end to a distal end and defining a device lumen therethrough, the scaffold being formed from a plurality of interconnected and articulated members configured to self-expand from a closed configuration to an open configuration, a plurality of barbs extend from the articulated members with each barb, including an anchoring end, the anchoring end being disposed radially outward from the scaffold in the open configuration and adapted to embed into the cavity walls, a radially expandable inner matrix being disposed within the device lumen and attached to at least one of the articulated members the inner matrix being configured to promote body tissue growth within the body cavity; and the occlusion device being coaxially arranged within the sheath lumen in the closed configuration such that the inner matrix is compressed within the device lumen, the occlusion device being deployable through the distal part of the outer sheath by relative axial movement of the outer sheath, and the scaffold, barbs, and extracellular matrix self-expand into the open configuration after deployment of the occlusion device. - View Dependent Claims (15, 16, 17, 18)
