Bioresorbable Inflatable Devices, Incision Tool And Methods For Tissue Expansion And Tissue Regeneration

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.

         3 . The device of  claim 1 , wherein a proximal portion of said container being inside said cannula, said filling material inside said cannula is passing through and touching said proximal portion of said container proximally to said distal end of said cannula. 
     
     
         4 . The device of  claim 1 , wherein at least part of said container being advanced from inside said cannula distally to said distal end of said cannula only by the advancement of said filling material. 
     
     
         5 . The device of  claim 1 , wherein said container being made at least partially from a bin-dissipative material and said filling material promotes the growth of bone. 
     
     
         6 . The device of  claim 1 , wherein the length of said cannula is larger than the height of said human alveolar ridge and said cannula includes an external thread for engaging said bony walls. 
     
     
         7 . The device of  claim 1 , wherein a proximal portion of said cannula includes inner screw threads, said distal portion of said connector includes outer screw threads, at least part of said distal portion of said connector threadably receivable in said proximal portion of said cannula, at least part of said container being located inside the distal portion of said cannula. 
     
     
         8 . The device of  claim 1 , wherein said container before being expanded being completely inside said cannula. 
     
     
         9 . The device of  claim 1 , wherein said proximal portion of said connector being wider than said distal portion of said connector. 
     
     
         10 . The device of  claim 1 , wherein at least part of said proximal portion of said connector being outside said cannula. 
     
     
         11 . The device of  claim 9 , wherein at least part of said proximal portion of said connector being outside said cannula. 
     
     
         12 . The device of  claim 1 , wherein said connector being fixated to said cannula. 
     
     
         13 . The device of  claim 1 , wherein said connector is a rigid tube. 
     
     
         14 . The device of  claim 1 , wherein said connector is a straight tube and said extension tube being bended. 
     
     
         15 . The device of  claim 1 , wherein a distal end of said extension tube being fixated inside said proximal portion of said connector. 
     
     
         16 . The device of  claim 1 , wherein said distal end of said connector being located proximally to the proximal end of said container. 
     
     
         17 . The device of  claim 1 , wherein at least part of said container being advanced from inside said cannula distally to the distal end of said cannula. 
     
     
         18 . The device of  claim 9 , wherein at least part of said distal tube of said connector being narrower than inner diameter of said cannula so as to leave a space between said at least part of said distal the of said connector and said cannula.
