Abstract
A tissue containment device (10) for isolating tissue from surrounding tissue during a surgical procedure to remove the tissue includes a bag (12) formed by one or more walls (14) defining a containment compartment (16) and an opening (18) for accessing the containment compartment. Each wall (14) is formed from at least two layers including an inner layer (20) facing the containment compartment and an outer layer (22) facing outwards from bag (12). The layers define between them one or more inflatable volumes (24). Layers (20) and (22) are interconnected at spaced-apart connection regions (28) that are arranged such that, when a fluid is introduced into the inflatable volumes (24), regions of the at least two layers between the connection regions form wall cavity regions surrounding an internal volume of the containment compartment.
