Hydrogel intrasaccular occlusion device

Abstract

The present disclosure relates to the field of endovascular treatment. More particularly, the present invention discloses a tool designed to implement an endovascular treatment capable of delivering medicine, such as amorphous hydrogel to wounds proximate to injury caused by endovascular treatment. Said hydrogel is affixed to an endovascular device.

9. The device of claim 2, wherein the thickness of at least one layer of said hydrogel decreases from the distal end to the proximal end of said device.

10. The device of claim 3, wherein the thickness of at least one layer of said hydrogel increases between the distal end to the proximal end of said device.

11. The device of claim 2, wherein the thickness of at least one layer of said hydrogel decreases between the distal end to the proximal end of said device.

12. The device of claim 2, wherein the thickness of at least one layer of said hydrogel is uniform from the distal end to the proximal end of said device.

13. The device of claim 2, wherein said hydrogel further includes at least on vasodilator.

14. The device of claim 1, adapted to treat intracranial saccular aneurysms.

15. The device of claim 1, adapted to treat extracranial saccular aneurysms.

16. The device of claim 1, adapted to treat arterial or venous aneurysms.

17. The device of claim 1, adapted for use in left atrial appendage closure.

18. The device of claim 1, adapted for use in an outpouching in the body.

19. The device of claim 1, adapted for use in diverticulae of other organs.

20. The device of claim 1, wherein said at least one material includes a biocompatible metal.

21. The device of claim 1, wherein said at least one material includes a biocompatible polyester.

22. The device of claim 17, wherein said polyester comprises polyethylene terephthalate (PETE or Dacron).

23. The device of claim 1, wherein said at least one material comprises a combination of a biocompatible metal and a biocompatible polyester.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The invention will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detail description thereof. Such description makes reference to the annexed drawings wherein:

[0041] FIG. 1 showing at distal end of wire (12) deployed device (10) designed to implement an endovascular treatment mesh (20) at treatment site with gel coat (22); optional lumens in wire (12) are not shown.

[0042] FIG. 2 showing at distal end of wire (12) showing undeployed device designed to implement an endovascular treatment mesh (20) with gel coat (22).

DETAILED DESCRIPTION OF THE INVENTION

[0043] The present disclosure teaches the placement of amorphous hydrogel within or coating surfaces of a device designed to implement an endovascular treatment. Said amorphous hydrogel is adhered to select surfaces of said device designed to implement an endovascular treatment and/or is contained by said device designed to implement an endovascular treatment, or both. When said coated designed to implement an endovascular treatment is proximately positioned at the treatment point, and the metal mesh device such as the Sequent Web or Luna Aneurysm Embolization system or similar system is deployed in the body, the exposure of the adhered added hydrogel with the device to the blood and temperature in the body causes it to expand further, decreasing the permeability of the device to blood and promoting more immediate thrombosis of the aneurysm, which results in more immediate decrease in the risk of the aneurysm rupturing.

[0044] Wire (12) may be solid or channeled with lumens. Said lumens are capable of delivering medication and packing materials. Said lumens are also capable of evacuating said packing materials and other material inside the device's hollow volume.

[0045] It will be understood that the above particular embodiment is shown and described by way of illustration only. The principles and the features of the present disclosure may be employed in various and numerous embodiments thereof without departing from the scope and spirit of the disclosure as claimed. The above-described embodiment illustrated the scope of the disclosure but does not restrict the scope of the disclosure.
