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.

Methods for dynamically evaluating blood flow are provided. The method may include injecting Indocyanine Green (ICG) into the bloodstream of a patient, such that the ICG perfuses into a tissue of the patient. ICG images of the tissue may be recorded and stored, such that a user may select a range of stored ICG images. Data indicative of the selected range of stored ICG images is automatically normalized and background-filtering, and a dynamic representation of the ICG perfusion may be generated as a function of time based on the normalized and filtered data. As such, a clinical decision may be made based on the dynamic representation of the ICG perfusion.
