Abstract
Abstract A stabilizer member includes a layer of malleable, shape-retaining material to be disposed on an external surface of tissue forming the wall of an anatomical cavity to allow one or more medical instruments to be inserted through the layer and into the anatomical cavity with the layer stabilizing the instruments longitudinally and angularly relative to the cavity wall. The malleable, shape-retaining properties of the layer allow it to be shaped by a surgeon to a desired configuration to, in turn, provide the cavity wall with a desired configuration creating or increasing the size of a space within the anatomical cavity.
