Abstract
Embolic implants, delivery systems and methods of manufacture and delivery are disclosed. The devices can be used for aneurysm treatment and/or parent vessel occlusion. Implant designs offer low profile compressibility for delivery to neurovasculature, while maintaining other necessary features such as density for occlusion purposes and desirable radial strength characteristics.
Claims23
An embolic device that is adapted to occlude an aneurysm, comprising:
- a braid body having a distal end region and a proximal end region, the braid body having a fold in the distal end region that forms an inner layer and an outer layer, the fold having a zero or near-zero radius bend between the inner and outer layers,
- wherein the outer layer is biased to transition from a compressed shape that is adapted for delivery through a catheter, to an expanded shape, the expanded shape of the outer layer converging towards the distal end region such that it is dome-shaped and converging towards the proximal end region of the braid body such that it is flared,
- wherein the inner layer is biased to transition from a compressed shape that is adapted for delivery through a catheter, to an expanded shape that defines an open, rounded volume, and
- wherein the inner and outer layers are coupled together at a hub in the proximal end region of the braid body, the hub having an open access port.

An embolic device adapted to occlude an aneurysm, comprising:
- a braid body having a distal end region and a proximal end region, the braid body having a fold in the distal end region that forms an inner layer and an outer layer,
- wherein the outer layer is biased to transition from a compressed shape that is adapted for delivery through a catheter, to an expanded shape, the expanded shape of the outer layer converging towards the distal end region and the proximal end region of the braid body, and
- wherein the inner layer is biased to transition from a compressed shape that is adapted for delivery through the catheter, to an expanded shape that is located within the outer layer.
An embolic device adapted to occlude an aneurysm, comprising:
- a braid body having a first end region and a second end region opposite the first end region, the braid body having a fold in the first end region that forms an inner layer and an outer layer,
- wherein the outer layer is biased to transition from a compressed shape that is adapted for delivery through a catheter, to an expanded shape, the expanded shape of the outer layer converging towards the first end region and the second end region of the braid body, and
- wherein the inner layer is biased to transition from a compressed shape that is adapted for delivery through the catheter, to an expanded shape that is located within the outer layer.
