A multi-wall expandable device (40) that optionally can have at least one material (46) between, Outside, or inside m the walls (43, 44) of the device. The sheet of material can be solid, perforated, or strands. Alternatively, individual strand or strands (47) of material may be woven through structural segments of the multi-wall expandable device. The sheet or sheets of material, strand, or strands can be used as a reservoir for any substance to be delivered, such as a drug, a supplement, a mineral or biological materials such as stem cells or a combination thereof. Additionally, the device is designed with the length of the device capable of being opened and closed to facilitate placement surrounding the treated structure to form a splint to offer support, protection, facilitate healing and deliver drugs or biological materials to the treated structure. This capability of being openable and closable can be accomplished with the use of latches, hinges, or memory metals such as nitinol.
