Abstract

Bioresorbable inflatable devices and tunnel incision tool and methods for treating and enlarging a tissue or an organ or a tube or a vessel or a cavity. The device is composed of a hollow expanding pouch made of a resorbable material or a perforated material that can be attached to a filling element. The pouch can be filled with a biocompatible materials, one or more times in few days interval, after the insertion of the device. While filling the pouch every few days the tissue expands and the filling material if it is bioactive start to function. The tunnel incision tool composed of a little blade that emerges from the surface of the tool in order to make shallow incisions in the surrounding tissue therefore enabling easy expansion of the tissue. This device and method can be used for example for: horizontal and vertical bone augmentation in the jaws and the tunnel incision tool is used to make shallow incisions in the periosteum when using the tunnel technique, sinus augmentation when the device is placed beneath the Schneiderian tissue, vessels widening if the pouch become a stent, fixating bone fractures etc.

Claims

1. A method for treating a bone within a living body comprising:

(a) creating a tunnel inside a bone through the periosteal tissue of said bone, said tunnel, where it is passing through said periosteal tissue, being surrounded all around by said periosteal tissue, said bone being touched from one side by a first covering tissue of said bone and from another side being touched by a second covering tissue of said bone;

(b) inserting a tube through said tunnel inside said bone;

(c) advancing at least part of a folded expandable portion of a container through said tube inside said bone, the external surface of said expandable portion of said container having at least one region which includes at least one opening which is open sufficiently to allow penetration of bone tissue and blood vessels;

(d) expanding said expandable portion of said container so that the majority of the external surface of said expandable portion of said container is touching a tissue selected from the group consisting of bone, periosteal tissue and Schneiderian membrane and said opening is facing a bone surface of said bone, said expanding of said expandable portion of said container is unfolding said expandable container and displacing said first covering tissue from said second covering tissue so the distance between said first covering tissue to said second covering tissue is increased;

(e) taking out said tube and leaving said expandable container inside said bone, so bone tissue can regenerate inside said expandable container to enlarge the height of said bone.

2. The method of claim 1, wherein said expanding is done by introducing a bone augmenting material inside said expandable container.

3. The method of claim 2, wherein said expandable container includes an area which is less penetrable to tissue than said region.

4. The method of claim 3, wherein said expandable container is perforated.

5. The method of claim 4, wherein said tunnel is surrounded all around by bone.

6. A method for augmenting the maxillary sinus and the nose comprising:

(a) creating a hole in the maxillary bone towards the Schneiderian membrane;

(b) Inserting through said hole a hollow tube, the external surface of said tube includes at least one protrusion to prevent slipping of said tube inside the maxillary sinus;

(c) Inserting through said tube a bone augmenting material to be between said Schneiderian membrane and said maxillary bone.

7. The method of claim 6, wherein said protrusion is a thread.

8. The method of claim 6, wherein said hole is done while preserving the integrity of said Schneiderian membrane.

9. The method of claim 8, wherein the location of said tube is adjustable.

10. The method of claim 8, wherein said tube includes a sealing means.

11. A device for treating a bone within a living body comprising:

a hollow tube for insertion inside bone and a folded expandable container inside said tube, the external surface of said expandable portion of said container having at least one region which includes at least one opening which is open sufficiently to allow penetration of bone tissue and blood vessels, said expandable container is designed to be pushed outside said container inside said bone so said region will be in contact with a bone surface.

12. The device of claim 11, wherein said container includes a filling conduit.

13. The device of claim 11, wherein said container is made at least partially from a bio-dissipative material.

14. The device of claim 11, wherein said container is made from a biocompatible implanted material.

15. The device of claim 11, wherein said container is designed to be closed after filling of said container.

16. A method for augmenting the maxillary sinus and the nose comprising:

(a) creating a hole in the maxillary bone towards the Schneiderian membrane;

(b) inserting through said hole a hollow tube, the external surface of said tube includes at least one protrusion to prevent slipping of said tube inside said bone;

(c) inserting through said tube an expandable container so said tube prevents damaging slipping of the base of said expandable container inside said maxillary sinus;

(d) expanding said expandable container between said Schneiderian membrane and said maxillary bone so as to displace said Schneiderian membrane from said maxillary bone.

17. The method of claim 16, wherein said expandable container is expanded by inflation.

18. The method of claim 17, wherein said hole is created while preserving the integrity of the Schneiderian membrane.

19. The method of claim 18, wherein after said expanding the majority of the external surface of said expandable container is touching said Schneiderian membrane.

20. The method of claim 19, wherein said expandable container is completely below said displaced Schneiderian membrane.
