Abstract

The present invention teaches the use of a disc shaped mesh intrasaccular occlusion structure with at least one hole in said disc, with optional supplemental hydrogel, which is designed to implement an endovascular treatment to facilitate saccular aneurysm treatment while ameliorating or eliminating aneurysm recurrence.

Claims

1. An embolic device configured for ameliorating bodily outpouchings, comprising a control element, a catheter element, a delivery microcatheter hypotube, a detachment element, a flattened mesh disc, a distal opening and at least one hole in said mesh disc;

wherein said catheter element further comprises at least one side hole;

further comprising at least two centering balloon deployed via said at least one side hole; and

wherein said mesh disc further comprises a proximal face and a distal face, said proximal face being opposite of said distal face; and

said proximal face and said distal face are substantially flat; and

wherein said mesh disc upon deployment is disposed distally and is configured to be in communication with an aneurysmal neck; and

wherein said mesh disc further comprises peripheral lips are configured to be oriented parallel to said aneurysmal neck;

wherein said peripheral lips are configured to overhang and rest on a base of said aneurysmal neck.

2. The device of claim 1, wherein said mesh disc is flexible.

3. The device of claim 1, wherein said delivery hypotube further comprises a channel capable of delivering at least one coil therethrough.

4. The device of claim 1, wherein said mesh disc is capable of deploying hydrogel in a sufficient amount to fill said outpouchings.

5. The device of claim 4, wherein said hydrogel is delivered through said delivery hypotube for deployment by said mesh disc.

6. The device of claim 1, wherein said mesh disc is impregnated with said hydrogel in a sufficient amount to substantially fill said outpouchings.

7. An embolic device for ameliorating bodily outpouchings, comprising a control element, a catheter element, a wire, a detachment element, a mesh disc and a distal opening;

wherein said catheter element further comprises at least one side hole;

further comprising at least two centering balloon deployed via said at least one side hole; and

wherein said mesh disc further comprises a proximal face and a distal face, said proximal face being opposite of said distal face; and

said proximal face and said distal face are substantially flat;

wherein said mesh disc upon deployment is disposed distally and is configured to be in communication with an aneurysmal neck; and

wherein said mesh disc further comprises peripheral lips are configured to be oriented parallel to said aneurysmal neck;

wherein said peripheral lips are configured to overhang and rest on a base of said aneurysmal neck.

8. The device of claim 7, wherein said mesh disc is flexible.

9. The device of claim 7, wherein said mesh disc is capable of deploying hydrogel in a sufficient amount to fill said outpouchings.

10. The device of claim 7, wherein said mesh disc is impregnated with said hydrogel in a sufficient amount to substantially fill said outpouchings.

11. The device of claim 7, wherein the periphery of said mesh disc is upturned.

12. The device of claim 7, wherein said mesh disc is configured to be positioned at the neck of bodily outpouchings.

13. The device of claim 12, wherein said mesh disc is configured not to substantially fill said bodily outpouchings.
