Abstract
A retraction device, e.g., a programmable stiffness state tissue displacement device, for providing increased visibility during an operation is provided. The device includes one or more strips of compliant jammable layer components connected in parallel, and encapsulated within a flexible envelope such that each of the one or more strips of compliant jammable layer components are pneumatically connected. The device further includes a negative pressure pump coupled to the flexible envelope, such that the application of negative pressure to the flexible envelope by the negative pressure pump causes the one or more strips of compliant jammable layer components to jam and thereby transition the retraction device from a malleable state to a rigid state.
