Vanderbilt researchers have developed a novel variable stiffness spring mechanism that affords low energy cost stiffness adaptation. Essentially, the energy cost of changing the stiffness of the spring is rendered independent of the energy stored in the spring.

Vanderbilt researchers have developed a novel system for allowing surgical instruments to navigate around tighter corners and access difficult-to-reach areas in the body. This system uses pre-curved elastic elements added on to the existing instrument. Current surgical instruments are manufactured in a straight-line configuration, which means they must bend in order to reach around obstructions in surgery. By adding pre-curved sections, some of the bending is already accomplished, allowing the instrument to bend around tighter corners.

An assistive device for individuals with upper extremity neuromuscular deficit has been developed by researchers at Vanderbilt. This device is specifically designed for patients having hemiplegia following stroke, incomplete spinal cord injury, multiple sclerosis, and other disabilities and conditions, who may have severe muscle weakness or inability to fully control an upper limb. In order to facilitate use of the upper limb, the patient can wear the device as a substitute for or a supplement to the patient's volitional movement.

Gastric cancer is the second leading cause of cancer death worldwide. While screening programs have had a tremendous impact on reducing mortality, the majority of cases occur in low and middle-income countries (LMIC). Typically, screening for gastric and esophageal cancer is performed using a flexible endoscope; however, endoscopy resources for these settings are traditionally limited. With the development of an inexpensive, disposable system by Vanderbilt researchers, gastroscopy and colonoscopy can be facilitated in areas hampered by a lack of access to the appropriate means.
