Abstract
Disclosed herein is a method of fractional treatment of tissue, the method comprising: creating at least one micro hole in a target tissue; and either a) applying pressure on said target tissue to decrease the patency of said at least one micro hole; administering material and/or fluid and/or drug onto said target tissue; releasing said applied pressure on said target tissue to increase the patency of said at least one micro hole; and propelling said material and/or fluid and/or drug into said at least one micro hole; or b) administering material and/or fluid and/or drug onto said target tissue under sub-atmospheric pressure conditions, the patency of said at least one micro hole being decreased; increasing the atmospheric pressure to atmospheric or above atmospheric conditions to thereby increase the patency of said at least one micro hole; and propelling said material and/or fluid/and/or drug into said at least one micro hole.
