Abstract: A medical device comprising a memory, a processor communicably coupled to the memory, and the processor configured to execute instructions to evaluate one or more patient data inputs relating to a first specific disease, compare the one or more data inputs to a set of values from at least one database using at least one computational algorithm, train the at least one computational algorithm for estimating a diagnosis of the patient based on the first specific disease, determine a first diagnostic score for the patient for the specific disease using the at least one computational algorithm, diagnose the patient as having the specific disease when the first diagnostic score for the first specific disease is above a first value, and provide the diagnosis for the patient as an output.

Abstract: The present invention provides a contact surface between the blade of a surgical retractor and an underlying tissue that directly reduces the injury of the tissue caused by the application of pressure during the retraction process. The embodiments of the present invention all use at least one inflatable chamber to form the contact surface, and the contact surface is then placed on the upper face of an otherwise plain surgical retractor blade. If a single inflatable chamber or interconnected group of inflatable chambers forms the retractor assembly's contact surface, it/they will be inflated and deflated in a cyclic manner to intermittently relieve the pressure applied to the underlying tissue.
