Abstract: A workspace device comprising: (a) a workspace body having a workspace inner wall defining an internal volume, including one or more expandable segments, said workspace body is: collapsible to a collapsed state where said body fits through a laparoscopic passageway in an abdominal wall, which passageway extends to an abdominal cavity; and expandable, to increase said internal volume, to an expanded state within said cavity, where, in said expanded state said workspace body: has an opening to said internal volume; and extends axially from a proximal to a distal direction defining a workspace axis; (b) one or more channels sized and shaped to supply inflation fluid to said workspace body; (c) said workspace body including: a plurality of circumferentially extending inflatable segments; a fluid pathway connecting at least one of said one or more channels to at least one of said segments.

Abstract: A workspace device having a body which is collapsible to a collapsed state to fit through a laparoscopic passageway in a body cavity wall, and expandable to an expanded state within a body cavity into which the passageway extends, including: a workspace body having a workspace wall including a plurality of expandable segments defining an internal lumen, and a plurality of radial rigidizers positioned within the wall; wherein in the expanded state: the workspace device extends defining a workspace axis, and has an opening to the internal volume; and the plurality of expandable segments rigidize the workspace body to resist collapse by intra-abdominal forces, and the plurality of radially extending rigidizers positioned within the wall resist radial forces.

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.
