1. A tissue containment device for isolating tissue from surrounding tissue during an intra-body surgical procedure, the device comprising:
a bag comprising one or more walls, defining a containment compartment having an internal volume and an opening for accessing said internal volume, wherein said one or more walls are formed from at least two layers comprising an inner layer and an outer layer, and a plurality of connection regions between said inner layer and said outer layer; wherein said inner layer faces said internal volume of said containment compartment, and said outer layer faces outwards from said bag, wherein said plurality of connection regions between the at least two layers define adjacent elongated inflatable deployment cavities, each of the inflatable deployment cavities comprising an inflatable volume; wherein in a pair of adjacent inflatable volumes of said inflatable deployment cavities, a first inflatable volume of said pair of adjacent inflatable volumes is located at an opposite side of a connection region of the plurality of connection regions, from a second inflatable volume of said pair of adjacent inflatable volumes, and
at least one inflation port in fluid connection with said inflatable volumes for introducing and removing a fluid to and from said inflatable volumes,
wherein said device is configured to be introduced in a compact uninflated state into a body cavity through a laparoscopic incision, and wherein said inflatable volumes are configured to be inflated inside said body cavity;
wherein said elongated inflatable deployment cavities are configured such that, when the fluid is introduced to said inflatable volumes, said adjacent elongated inflatable deployment cavities are inflated and press against each other when said device is deployed inside the body cavity of a subject body to form an inflatable volume structurally supporting a larger pressure outside the bag relative to pressure inside the internal volume of said containment compartment defined by the one or more walls of said bag, and to isolate tissue in said internal volume from tissue in said body cavity facing said outer layer, when said opening is outside said subject body.
