Abstract
A deployable occlusion device for filling an aneurysm. The occlusion device includes a support structure, for example a wire or otherwise elongate structure. The occlusion device also includes a mesh component having a porosity. The mesh component has a first end portion and a second end portion. The first end portion of the mesh component is attached to the support structure and the second end portion of the mesh component is a free end. The mesh component extends from the support structure.
Claims19
An implantable occlusion device for filling an aneurysm, the occlusion device comprising:
- a support structure configured to be implanted in the aneurysm, the support structure comprising a wire;
- and
- a plurality of mesh components, each mesh component comprising a porosity, each mesh component comprising a first end portion and a second end portion, the first end portion being attached to the support structure and the second end portion being a free end, each mesh component extending from the support structure,
- wherein each mesh component is configured to transition between a compressed state and an uncompressed state,
- wherein each mesh component comprises a disc having a slot, and
- wherein in the compressed state, each mesh component is wrapped around the support structure, the slot enabling the disc to be wrapped around the support structure with overlapping portions.
A method of deploying an occlusion device into an aneurysm, the method comprising:
- advancing a delivery system carrying the occlusion device to the aneurysm, the occlusion device comprising a support structure and a plurality of mesh structures extending from the support structure, the plurality of mesh structures wrapped around the support structure in a constrained configuration when loaded in the delivery system, each mesh structure having a slot enabling the mesh structure to be wrapped around the support structure with overlapping portions;
- deploying the occlusion device from the delivery system and into the aneurysm, causing each of the plurality of mesh structures to unfold from the constrained configuration to an expanded configuration to enhance an occlusive surface area per unit length of the support structure;
- and
- releasing the occlusion device from the delivery system.
