ABSTRACT:
A medical device such as a retractor or isolation bag including an inflatable member which expands from a collapsed configuration to an expanded configuration when pressurized gas or liquid is supplied thereto. The member can include a plurality of fluid channels, ribs and pre-shaped wire members. The device is inserted into a body cavity through a tube. The device can also be actuated by a honeycomb reinforcing structure with or without the use of pressurized fluid. The device can be manufactured by forming one or more air conduits in a member of expandable material or by enclosing a honeycomb reinforcing structure in a polymer material.
