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.

Abstract
A void containment apparatus and its method of use during an invasive procedure on the body are disclosed. The void containment apparatus includes an elongated housing and a balloon. The balloon is capable of being inflated and deflated. When inflated, the balloon provides a seal around a void and allows delivery or extraction of material into or out of the void with minimal leakage outside the void.

14. An apparatus for use in a surgical environment for filling bone defect, wherein the bone defect is a void, the apparatus comprising:
-
an elongated tubular housing having a plurality of chambers, which includes an inner chamber having an inside wall and an outside wall, and an outer chamber surrounding said inner chamber, wherein each chamber is isolated from the other chamber, the inner chamber has an opening providing an entrance at the proximal end and an outlet at the distal end, wherein the inner chamber is used for housing material, a piston disposed in said inner chamber and movable relative to the chamber between the proximal end and the distal end of said inner chamber, wherein one end of the piston that is disposed in the said chamber includes a sealing engagement member that abuts the inner wall of the inner chamber thereby creating a seal between the inner wall of the inner chamber and the piston, and a plurality of inflatable balloons coupled to the elongated tubular housing, wherein one of the inflatable balloons is located at the distal end of the elongated tubular housing and is used for creating a seal between the void, its surrounding environment, and the apparatus thereby allowing deposition of material located in the inner chamber. - View Dependent Claims (15, 16)
