Method for tissue expansion and regeneration using bioresorbable inflatable devices
First Claim
1. A method for treating bone within a living body comprising:
- (a) creating a hole in a periosteal tissue of a bone for insertion of an expandable portion of a container, said bone having a bone surface, said bone surface being touched by a covering tissue of said bone, said covering tissue is selected from the group consisting of periosteal tissue and Schneiderian membrane;
(b) prior to inserting said expandable portion of said container, forming a subperiosteal tunnel between said bone and said periosteal tissue, for insertion of said expandable portion of said container,(c) inserting through said hole between said bone surface and said covering tissue said expandable portion of said container, 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 portion of said container includes an area which is less penetrable to tissue than said region;
(d) expanding said expandable portion of said container so that said opening is facing said bone surface and at least part of said area is facing said covering tissue, said expanding of said expandable portion of said container is displacing said area to displace said covering tissue from said bone surface so the distance between said covering tissue to said bone surface is increased to allow bone regeneration between said covering tissue and said bone surface.

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 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 etc.
