Steerable Needles: A Better Turning Radius with Less Tissue Damage

A team of Vanderbilt engineers and surgeons have developed a new steerable needle that can make needle based biopsy and therapy delivery more accurate. A novel flexure-based tip design provides enhanced steerability while simultaneously minimizing tissue damage. The present device is useful for almost any needle-based procedure including biopsy, thermal ablation, brachytherapy, and drug delivery.

Non-Invasive Skin Cancer Detection using Raman Spectroscopy-OCT System (Portfolio)

Vanderbilt University researchers have designed a system for non-invasive discrimination between normal and cancerous skin lesions. The system combines the depth-resolving capabilities of OCT technique with Raman Spectroscopy's specificity of molecular chemistry. By linking both imagining techniques into a single detector arm, the complexity, cost, and size of previously reported RS-OCT instruments have been significantly improved. The combined instrument is capable of acquiring data sets that allow for more thorough assessment of a sample than existing optical techniques.

Systems and Methods for Optical Stimulation of Neural Tissues (Portfolio)

Vanderbilt researchers have developed a novel technique for contactless simulation of the central nervous system.  This involves the use of infrared neural stimulation (INS) to evoke the observable action potentials from neurons of the central nervous system.  While infrared neural stimulation of the peripheral nervous system was accomplished almost a decade ago, this is the first technique for infrared stimulation of the central nervous system. This technology has been protected by a portfolio of issued patents.

MAESTRO: Non-Robotic Dexterous Laproscopic Instrument with a Wrist providing seven degrees of freedom

Inventors at Vanderbilt University have developed a non-robotic dexterous laparoscopic manipulator with a wrist providing seven-degrees-of-freedom. It provides an interface which intuitively maps motion of the surgeon's hands to the tool's ""hands"". The novel user interface approach provides a natural mapping of motion from the surgeon's hands to the instrument tips.

Two Degrees-of-Freedom, Fluid Power Stepper Actuator Model

Vanderbilt researchers have developed a novel technology for use of a flexible fluidic actuator in MRI-guided surgical systems. This method eliminates the need for moving the patient out of the MRI machine, onto an operating table, and back in order to perform procedures. It is a safe, sterilized, and successful method to simplify MRI-guided surgical procedures.

Guide Wire Torque Device for Interventional Medical Procedures

Vanderbilt University researchers have created a torque device that allows surgeons to apply better torque and grip to guide wires used in interventional medical procedures.

Catheter Having Temperature Controlled Anchor and Related Methods

Heart valve disease is the 3rd most prevalent source of cardiovascular disease, leading to approximately 20,000 deaths per year in the U.S. alone. Moreover, there are an estimated 41,000 mitral valve procedures performed in the U.S. each year. The only effective, long-term treatment for mitral valve disease is open-chest valve replacement surgery, which is highly undesirable for elderly patients. Thus, there is a pressing need to develop novel percutaneous strategies for treatment that will reduce the number of open-chest surgeries. David Merryman and colleagues have developed a new, combined catheter that uses cryo temperatures to adhere to moving mitral valve leaflets and radiofrequency ablation to alter the compliance of the leaflet tissue to prevent prolapse and regurgitation.

Flexure Wrist for Surgical Devices

Vanderbilt researchers have designed a flexible wrist for use with manual or robotic surgical systems.

Transoral Lung Access Device

Transoral lung access is preferable to traditional needlebasedaccess due to the lower risk of lung collapse. However present bronchoscope-based devices enable access to only a small portion of the lung. The present device is a robotic image-guided bronchoscope to navigate the airway under closed-loop control to the target. IT is designed to provide transoral access to any location in the lung, particularly the hard-to-reach peripheral regions.

Inexpensive Disposable Hydro-Jet Capsule Robot for Gastric Cancer Screening in Low-Income Countries

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.
