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 displacing the Schneiderian membrane from the maxillary bone comprising:

a. Forming a path of insertion through a segment of the maxillary bone towards the Schneiderian membrane covering said segment of the maxillary bone, while preserving the integrity of said Schneiderian membrane;

b. Inserting an expandable inflatable element through said path of insertion;

c. Expanding said expandable element so as to displace said Schneiderian membrane from said maxillary bone and creating a space between the upper part of said segment of the maxillary bone and said displaced Schneiderian membrane, said upper part of said segment of the maxillary bone is selected from the group consisting of the floor of the maxillary sinus and the floor of the nasal cavity.

2. The method of claim 1, wherein said expandable element includes a filling conduit, said expanding of said expandable element is done by introducing a filling material though said filling conduit.

3. The method of claim 2, wherein at least part of said expandable element is located in said space.

4. The method of claim 3, wherein the integrity of said displaced Schneiderian membrane is preserved during the displacement of said Schneiderian membrane.

5. The method of claim 4, wherein said expandable element is completely below said displaced Schneiderian membrane.

6. The method of claim 4, wherein said expandable element is made from an elastic material.

7. The method of claim 3, wherein said expandable element includes a bio-dissipative material so said bio-dissipative material is touching said displaced Schneiderian membrane.

8. The method of claim 3, wherein said expandable element includes a guided bone regeneration membrane so said guided bone regeneration membrane is touching said displaced Schneiderian membrane.

9. The method of claim 4, wherein said filling conduit is connected to a syringe, said syringe has inside said filling material and said filling material is syringed through said filling conduit inside said expandable element.

10. The method of claim 4, wherein said introducing is performed in a plurality of stages, each stage incrementally displacing said displaced Schneiderian membrane.

11. The method of claim 4, wherein at least part of said expandable element is made from a biocompatible material and said part of said expandable element is inside the body for at least several days.

12. The method of claim 4, wherein said expandable element includes a perforated region, said perforated region is facing said upper part of said segment of the maxillary sinus.

13. The method of claim 12, wherein said filling material is a bone augmenting material.

14. The method of claim 12, wherein said filling material promotes the growth of bone tissue.

15. The method of claim 14, wherein the region of said expandable element that is touching said displaced Schneiderian membrane is less perforated than said perforating region facing said upper part of said segment of the maxillary sinus.

16. The method of claim 9, wherein said filling conduit is made from a rigid material, said rigid filling conduit can be fixated to said segment of the maxillary bone.

17. The method of claim 16, wherein said path of insertion is formed inside the alveolar ridge and the length of said rigid filling conduit is fitted to the height of the said alveolar ridge.

18. The method of claim 17, wherein said rigid filling conduit has external thread to allow its fixation to said alveolar ridge.

19. The method of claim 4, wherein the shape of said expandable element after expanding can be dictated.

20. The method of claim 19, wherein said expandable element is allowed first to expand horizontally and afterwards vertically.
