Abstract: Some systems, devices and methods detailed herein provide adjustable tissue retraction, for example, to maintain an access opening during a surgical procedure.

Abstract: A surgical retractor for positioning within an incision within a body of a patient is described. The surgical retractor comprises a flexible air-impermeable bag surrounding an interior region and extending from a first end through a central region to a second end. The surgical retractor includes a first port in the central region, the flexible air-impermeable bag surrounding a first channel that extends from the first port towards the first end, a second port in the central region, the flexible air-impermeable bag surrounding a second channel that extends from the second port toward the second end, and a plurality of beads substantially filling the interior region of the flexible air-impermeable bag. The flexible air-impermeable bag is configured to rigidify in response to air being evacuated from the interior region to position and hold intra-incision contents within a surgical working space in a patient.
