Bioresorbable Inflatable Devices, Incision Tool And Methods For Tissue Expansion And Tissue Regeneration
First Claim
1. A method for treating a paranasal sinus comprising:
- (a) inserting inside a sinus at least part of an expandable inflatable element while keeping the integrity of the mucosal tissue covering the walls of said sinus;
(b) expanding said expandable inflatable element so that the majority of the external surface of said expandable inflatable element is touching and displacing said mucosal tissue.

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.

6. 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 through said tube inside said bone a movable element; (d) inserting through said tube rigid elements so said rigid elements are displacing said movable element 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 movable element and said rigid elements inside said bone, so the height of said bone is enlarged. - View Dependent Claims (7, 8, 9, 10)

11. A device for displacing of the Schneiderian membrane comprising:
a hollow tube for insertion through the maxillary bone towards the Schneiderian membrane and an expandable inflatable container, said tube having on the external surface at least one protrusion to prevent slipping of said tube inside said maxillary sinus, the proximal end of said tube is attached to said expandable inflatable container, the distal end of said tube is configured to be attached to an injecting device so a filling material can be inserted through said tube inside said expandable inflatable container. - View Dependent Claims (12, 13, 14, 15)

16. A device for insertion of bone augmenting material inside the maxillary sinus comprising:
a hollow tube for insertion through the maxillary bone towards the Schneiderian membrane, said tube having on the external surface at least one protrusion to prevent slipping of said tube inside said maxillary sinus, the distal end is configured to be attached to an injecting device so bone augmenting material can be inserted through said tube inside said maxillary sinus. - View Dependent Claims (17, 18, 19, 20)
