Abstract

The present invention teaches the uses of a disc shaped mesh intrasaccular occlusion structure, 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 for ameliorating bodily outpouchings, comprising

a control element,

a catheter element,

a delivery microcatheter hypotube,

a detachment element,

a mesh disc,

a distal opening,

at least one side hole,

and at least two centering balloons deployed via said at least one side hole to position said catheter element in relation to the center of a target aneurysmal neck,

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

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

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

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

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

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

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

4. The device of claim 3, wherein said hydrogel is delivered through said delivery hypotube for deployment by said mesh disc.

5. The mesh disc according to claim 1, wherein said mesh disc is at least 4 mm in width.

6. The device of claim 5, further comprising adhered hydrogel.

7. The device of claim 1, further comprising adhered hydrogel.

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

8. An embolic device for ameliorating bodily outpouchings, comprising a control element, a catheter element, a wire, a detachment element, a mesh disc, a distal opening, at least one side hole, and at least two centering balloons deployed via said at least one side hole to position said catheter element in relation to the center of a target aneurysmal opening:

wherein said mesh disc further comprises 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 said aneurysmal opening;

wherein said mesh disc further comprises peripheral lips configured to be oriented parallel to said aneurysmal opening,

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