Vanderbilt researchers have discovered a method ofmonitoring the placement of electrodes in cochlearimplants (CIs) through the use of electrical impedancemeasurements. This technology offers real-timefeedback on electrode positioning, which can beused to more accurately place electrodes duringinitial implantation, or better program the implantsafter they have been placed. These enhancementscombine to give increased hearing quality to bothnew and existing CI patients.

Vanderbilt engineers have developed a robotic system for performing sinus and neurosurgery through the nose. This provides a less invasive way to access surgical sites in the sinuses and near the middle of the patient's head, leading to faster recovery times. The robot is modular and sterilizable with detachable cartridge-based instruments. Each instrument is a concentric tube robot, which is a needle-sized tool that can bend and elongate. The system delivers four of these instruments through a single nostril.

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.
