US Patent 10251801 Deployable compact surgical and biological apparatus and methods of use

A collapsible containment apparatus (36) with a first hub (21), a second hub (22), a plurality of articulated arms (23, 25) coupled to the first hub (21), a plurality of support arms (24) coupled to both the second hub (22) and the articulated arms (23), and a flexible canopy (73) carried by the articulated arms (23). The apparatus (36) is collapsed by relative movement of the two hubs (21, 22) away from one another, and deployed by relative movement of the hubs (21, 22) toward one another. When the apparatus (36) is deployed the canopy (73) creates a closed interior environment, which may be sterile.
