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.


Robust Learning Algorithms in Adversarial Environments

Vanderbilt engineers have developed an algorithmic framework for machine learning under the threat of adversarial evasion. The framework leverages a game theoretic model of interaction between the learner and an evading attacker, and makes use of modern optimization tools to increase robustness of learning algorithms as they are used in operational settings.


Data-driven Agent-based Modeling Architecture

A team of engineers at Vanderbilt University has developed a data-driven agent-based modeling framework that can be used in forecasting consumer behavior for product adoption purposes. The architecture turns agent-based modeling into a reliable forecasting tool at both individual and population level resolutions.


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.
