Abstract:
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.
