The device has dimensions in the second, collapsed condition suitable for insertion through vasculature of the patient and through a neck of the aneurysm. The device further includes a control ring having a substantially annular body disposed on the proximal end region of the structure and at least substantially circumscribing the proximal end region to prevent radial expansion of the proximal end region and to provide an engagement feature during manipulation of the occlusion device. ## Claims ### Claim 1 A system suitable for endovascular treatment of an aneurysm in a blood vessel in a patient, comprising: an occlusion device having a substantially tubular braided mesh structure having a proximal end region and a distal end region and a control ring having a substantially annular body disposed on the proximal end region of the tubular structure, the control ring at least partially circumscribing the proximal end region to prevent radial expansion of the proximal end region and to provide an engagement feature during manipulation of the occlusion device; a delivery member having a distal end region carrying a grabber having at least two finger elements, each finger element including a notch configured to engage the control ring such that the occlusion device and delivery member are in mechanical communication, the notch having an inner top surface and an inner bottom surface defining an inner cavity having a height approximately equal to a thickness of the control ring; and an embolic implant delivery catheter capable of delivering an embolic implant to the aneurysm, wherein the tubular structure is expandable from a collapsed condition to an expanded condition, wherein in the collapsed condition, the tubular structure is suitable for insertion through vasculature of a patent and through a neck of the aneurysm, and wherein in the expanded condition, the tubular structure has a substantially hemispherical shape and has an exterior surface capable of contacting the aneurysm and capable of providing a force to appose the embolic implant delivery catheter to the aneurysm. ### Claim 2 (depends on 1) The system of claim 1 wherein the tubular structure of the occlusion device in the expanded condition is capable of supporting the embolic implant in the aneurysm. ### Claim 3 (depends on 1) The system of claim 1 wherein the control ring is crimped onto the proximal end region of the tubular structure. ### Claim 4 (depends on 1) The system of claim 1 wherein the control ring includes radiopaque material. ### Claim 5 (depends on 1) The system of claim 1 wherein the tubular structure includes a plurality of filaments. ### Claim 6 (depends on 1) The system of claim 1 wherein the tubular structure defines a substantially enclosed volume. ### Claim 7 (depends on 1) The system of claim 1 wherein at least a portion of the proximal end region of the tubular structure defines a plurality of openings having a sufficiently small size to enhance occlusion of the aneurysm. ### Claim 8 (depends on 1) The system of claim 1 wherein the delivery member is a tube formed of at least one metallic material. ### Claim 9 (depends on 1) The system of claim 1 wherein the grabber is formed of a metallic material. ### Claim 10 (depends on 1) The system of claim 1 further including an occlusion device delivery catheter having an inner lumen through which the delivery member is insertable and translatable relative to the occlusion device delivery catheter. ### Claim 11 A system suitable for endovascular treatment of an aneurysm in a blood vessel in a patient, comprising: an occlusion device having a substantially tubular structure having a proximal end region and a distal end region and a control ring having a substantially annular body disposed on the proximal end region of the tubular structure, the control ring at least partially circumscribing the proximal end region to prevent radial expansion of the proximal end region and to provide an engagement feature during manipulation of the occlusion device; and a delivery member having a distal end region carrying a grabber having at least two finger elements, each finger element including a notch configured to engage the control ring such that the occlusion device and delivery member are in mechanical communication, the notch having an inner top surface and an inner bottom surface defining an inner cavity having a height approximately equal to a thickness of the control ring; and an embolic implant delivery catheter capable of delivering an embolic implant to the aneurysm, wherein the tubular structure is expandable from a collapsed condition to an expanded condition. ### Claim 12 (depends on 11) The system of claim 11 wherein in the collapsed condition, the tubular structure is suitable for insertion through vasculature of a patent and through a neck of the aneurysm. ### Claim 13 (depends on 11) The system of claim 11 wherein the expanded condition, the tubular structure has a substantially hemispherical shape and has an exterior surface capable of contacting the aneurysm and capable of providing a force to appose the embolic implant delivery catheter to the aneurysm. ### Claim 14 (depends on 11) The system of claim 11 wherein the tubular structure of the occlusion device in the expanded condition is capable of supporting the embolic implant in the aneurysm. ### Claim 15 (depends on 11) The system of claim 11 wherein the control ring is crimped onto the proximal end region of the tubular structure. ### Claim 16 (depends on 11) The system of claim 11 wherein the control ring includes radiopaque material. ### Claim 17 (depends on 11) The system of claim 11 wherein at least a portion of the proximal end region of the tubular structure defines a plurality of openings having a sufficiently small size to enhance occlusion of the aneurysm. ### Claim 18 (depends on 11) The system of claim 11 wherein the delivery member is a tube formed of at least one metallic material. ### Claim 19 (depends on 11) The system of claim 11 wherein the tubular structure is a braided mesh structure including a plurality of filaments. ### Claim 20 (depends on 11) The system of claim 11 further including an occlusion device delivery catheter having an inner lumen through which the delivery member is insertable and translatable relative to the occlusion device delivery catheter.
