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 workspace device including (a) a body having a wall defining an internal volume, collapsible to fit through a laparoscopic passageway in an abdominal wall to an abdominal cavity and expand therein; (b) a first opening defined in said body; (c) a tool channel contiguous with said first opening and extending from said body and configured to remain, at least in part, outside of abdominal wall and sized to receive a laparoscopic tool therein therein; and (d) the body defining an orifice configured to lie in said abdominal cavity when said body is inserted therein, said orifice sized to receive tissue with a minimal cross-sectional area that is twice a minimal cross-sectional area of said first opening, thereby defining a workspace volume to process said tissue in said cavity while said body is not collapsed, using a tool inserted through said first opening.

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 surgical device for treating shoulder dystocia having a first arm having a proximal portion, a distal portion and a first curved surface, a second arm having a proximal portion, a distal portion and a second curved surface and a shoulder engagement section positioned at least between the distal portion of the first and second arms and connecting the first and second arms. The engagement section has an atraumatic surface and is configured to contact and press down on the baby to reposition the baby upon manipulation of the first and second arms.
