Abstract:
1. An apparatus for providing a seal around a void, wherein a void is cavity or defect in a bone or a missing piece of the bone material which starts on the outer surface of a bone and varies in depth, shape, and size and often contains uneven surfaces, the apparatus comprising: an elongated housing having a double chamber comprised of (1) a hollow outer chamber and (2) a hollow inner chamber positioned inside and surrounded by said hollow outer chamber, wherein both the inner chamber and the outer chamber have a proximal end and a distal end, wherein each of the inner and outer chambers has an opening on its proximal end, an opening on its distal end, and the opening on the proximal end is connected there-through to the opening on the distal end, wherein the outer chamber includes multiple ports that allow entry and exit of a first medium, wherein the first medium delivered into the outer chamber remains isolated from the inner chamber; and wherein the inner chamber allows entry of a second medium through its proximal end; and an inflatable balloon coupled to the distal end of the outer chamber of the elongated housing such that the only ingress and egress to the balloon is through the outer chamber, wherein the inflating of the inflatable balloon is performed through entry of the first medium from the outer chamber into the balloon, and wherein the first medium is contained within the boundaries of the inflatable balloon and the outer chamber thereby preventing leakage of the first medium outside the balloon and outer chamber to any of the surroundings of the apparatus, wherein the balloon in its inflated stage sits on the outside of the bone and surrounds the periphery of the void thereby creating a seal surrounding the void, wherein the seal allows deposition of the second medium through the inner chamber into the void without leakage of the second medium outside the sealed environment.
