Systems and methods for inserting biocompatible filler materials in interior body regions are described. In one described method, an expansible body comprising a body material substantially resistant to at least one of a biocompatible filler material and a chemical component of the biocompatible filler material may be inserted into a treatment area along a path established by a hollow member. The expansible body may then be expanded within the treatment area. The biocompatible filler material may be inserted into the treatment area while the expansible body is expanded therein. |
