초록 ▼

A device for at least partially occluding an aneurysm is disclosed. The device includes a first elongate member having a distal end. A bridge is positioned proximate the distal end and transformable between a delivery configuration and a deployed configuration. A second elongate member is movable relative to the first elongate member, the first and second elongate members being configured such that one can be moved relative to the other in order to transform the bridge between the delivery and deployed configurations.

1. A device to at least partially seal a neck of aneurysm, comprising: a first elongate member having a proximal end and a distal end and an elongated length therebetween;an aneurysm neck bridge releasably connected to the distal end of the first elongate member at a connection point, the aneurysm neck bridge having a proximal end and a distal end, the aneurysm neck bridge comprising:a first array having a deployed configuration and a delivery configuration, the first array formed proximate the distal end of the aneurysm neck bridge, wherein the first array forms a plurality of petal-like features when in the deployed configuration;a second array having a deployed configuration and a delivery configuration, the second array formed proximate the proximal end of the aneurysm neck bridge, wherein the second array forms a plurality of petal-like features when in the deployed configuration;a second elongate member having a proximal end and a distal end and an elongated length therebetween, the first elongate member and the first and second array being slidably received within the second elongate member, wherein the first and second array are configured to transform such that they are in the delivery configuration when contained within the second elongate member and are in the deployed configuration when outside the second elongate member. 2. The device of claim 1 wherein the aneurysm neck bridge is comprised of a single length of tubing. 3. The device of claim 2 wherein the single length of tubing comprises shape memory material. 4. The device of claim 3 wherein the shape memory material is heatset material. 5. The device of claim 2 wherein the first array and the second array include a plurality of slots formed therein. 6. The device of claim 1 wherein the second elongate member is a microcatheter. 7. The device of claim 1 wherein the second array is at least partially covered in a non-porous elastomeric material. 8. The device of claim 1 wherein the connection point is a GDC detachment zone. 9. The device of claim 8 wherein the bridge is released by an electrical charge at the GDC detachment zone. 10. A device to at least partially seal a neck of aneurysm, comprising: a first elongate member having a proximal end and a distal end and an elongated length therebetween;an aneurysm neck bridge releasably connected to the distal end of the first elongate member at a connection point, the aneurysm neck bridge having a proximal end and a distal end, the aneurysm neck bridge comprising:a first array having a deployed configuration and a delivery configuration, the first array formed proximate the distal end of the aneurysm neck bridge, in the deployed configuration said first array forms a plurality of protruding petal-like members that extend from, and are radially disposed around, the first elongate member;a second array having a deployed configuration and a delivery configuration, the second array formed proximate the proximal end of the aneurysm neck bridge, in the deployed configuration said second array forms a plurality of protruding petal-like members that extend from, and are radially disposed around, the first elongate member;a second elongate member having a proximal end and a distal end and an elongated length therebetween, the first elongate member and the first and second array being slidably received within the second elongate member, wherein the first and second array are configured to transform such that they are in the delivery configuration when contained within the second elongate member and are in the deployed configuration when outside the second elongate member. 11. The device of claim 10 wherein the aneurysm neck bridge is comprised of a single length of tubing. 12. The device of claim 11 wherein the single length of tubing comprises shape memory material. 13. The device of claim 12 wherein the shape memory material is heatset material. 14. The device of claim 12 wherein the first array and the second array include a plurality of slots formed therein. 15. The device of claim 10 wherein the second elongate member is a microcatheter. 16. The device of claim 10 wherein the second array is at least partially covered in a non-porous elastomeric material. 17. The device of claim 10 wherein the connection point is a GDC detachment zone. 18. The device of claim 10 wherein the bridge is released by an electrical charge at the GDC detachment zone.
