Beschreibung
Zusammenfassung:	A downhole completion assembly for sealing and supporting an open hole section of a wellbore includes a sealing structure movable between contracted and expanded configurations, a truss structure also movable between contracted and expanded configurations, wherein, when in their respective contracted configurations, the sealing and truss structures are each able to axially traverse production tubing extended within a wellbore, a conveyance device operably coupled to the sealing and truss structures and configured to transport the sealing and truss structures in their respective contracted configurations through the production tubing and to an open hole section of the wellbore, and a deployment device operably connected to the sealing and truss structures and configured to radially expand the sealing and truss structures from their respective contracted configurations to their respective expanded configurations.
