Abstract
Occlusion devices are disclosed herein. According to some embodiments, the present technology includes a mesh configured to be positioned within an aneurysm cavity, the mesh having a low-profile configuration for delivery through a catheter to the aneurysm cavity and an expanded configuration for implantation in the aneurysm cavity. The mesh can include a first portion configured to be positioned over the aneurysm neck and a second portion configured to be positioned between the first portion and a dome of the aneurysm. The mesh can include a copper material at the second portion of the mesh, wherein the copper material is configured to promote thrombosis within the aneurysm cavity.
Claims20
An occlusive device for treating an aneurysm, the device comprising:
- a mesh configured to be positioned within an aneurysm cavity, the mesh having a low-profile configuration for delivery through a catheter to the aneurysm cavity and an expanded configuration for implantation in the aneurysm cavity, wherein the mesh comprises:
- a first portion configured to be positioned over the aneurysm neck and a second portion configured to be positioned between the first portion and a dome of the aneurysm,
- a copper material at the second portion of the mesh and configured to promote thrombosis within the aneurysm cavity, and
- a plurality of braided filaments secured relative to one another at a coupler disposed at the second portion of the mesh, the coupler comprising the copper material, wherein at least a portion of the coupler is positioned at an outer region of the second portion to promote thrombosis within the aneurysm cavity between the second portion of the mesh and the dome of the aneurysm.
An occlusive device for treating an aneurysm, the device comprising:
- a mesh configured to be positioned within an aneurysm cavity, the mesh having a low-profile configuration for delivery through a catheter to the aneurysm cavity and an expanded configuration for implantation in the aneurysm cavity, wherein the mesh is defined by a sidewall that surrounds an interior cavity when the mesh is in the expanded configuration, and wherein the mesh comprises:
- a first portion configured to be positioned over the aneurysm neck and a second portion configured to be positioned between the first portion and a dome of the aneurysm,
- a copper material at the second portion of the mesh and configured to promote thrombosis within the aneurysm cavity, and
- a plurality of braided filaments secured relative to one another at a coupler disposed at the second portion of the mesh, the coupler comprising the copper material, and wherein at least a portion of the coupler is positioned within the interior cavity of the mesh to promote thrombosis within the interior cavity of the mesh.
