Abstract

An intrasaccular device particularly adapted for treating body lumens. The intrasaccular device includes structure that provides a strong framework as well as improved covering across an opening to an aneurysm sac. The intrasaccular device is intended to retain foreign bodies within the aneurysm sac and includes members for accomplishing this objective. The intrasaccular device is also provided with structure that facilitates the alignment of a plurality of devices deployed within the sac.

Claims

1. A device for insertion in a saccular cavity of a patient, comprising:

a body formed from a tubular member, the body including a first end, a second end and a midsection, the body further including a cage having an interior, each of the first and second ends configured within the interior of the cage; and

wherein the body is expandable from a reduced profile to an expanded profile, the reduced profile suited for insertion into the saccular cavity and the expandable profile defined at least in part by the saccular cavity.

2. The device of claim 1, wherein the body assumes a generally spherical profile when expanded.

3. The device of claim 1, wherein the midsection assumes a generally spherical profile when the body assumes the expanded profile.

4. The device of claim 1, wherein the body is self-expandable.

5. The device of claim 1, further comprising connecting structure formed at the first end.

6. The device of claim 1, further comprising connecting structure formed at the second end.

7. The device of claim 1, the first end further comprising a cylindrical nub and the midsection further comprising a plurality of longitudinally extending members, the longitudinally extending members each having a terminal end.

8. The device of claim 7, wherein the second end of the body is defined by the terminal ends of the plurality of longitudinally extending members.

9. The device of claim 8, wherein the terminal ends of the plurality of longitudinally extending members are affixed to each other.

10. The device of claim 1, the first end further comprising connecting structure, the connecting structure being recessed in the body.

11. The device of claim 1, the first end further comprising connecting structure, the connecting structure having a first portion and a second portion, the midsection further comprising a plurality of deformable members arranged to form a cage, each deformable member having a first terminal end and a second terminal end, the first portion of the connecting structure being attached to each of the first terminal ends of the deformable members.

12. The device of claim 11, wherein the connecting structure is configured within the interior of the cage.

13. The device of claim 1, wherein a plurality of members extend generally longitudinally.

14. The device of claim 1, the body further comprising connecting structure that is adapted to be positioned at an opening to the saccular cavity, the connecting structure facilitating an even distribution within the saccular cavity.

15. The device of claim 1, the first end further comprising a plurality of members, the members providing a strong framework across an opening to the saccular cavity.
