Wearable Metabolic Rate Sensor

Vanderbilt researchers have developed a portable, non-invasive sensor system that can take measurements through the skin to provide insights into metabolic rate and energy expenditure outside of a clinical setting. Existing methods for estimating metabolic rate rely on comparisons between user-reported body parameters and population averages, which can result in inaccurate estimates. Additionally, existing portable devices that provide estimates of metabolic rate are limited by factors such as cost per use and frequency of measurement. The present technology overcomes these limitations and can be directly integrated with commercial wearable devices for an accurate assessment of metabolic rate.

An Imaging Approach to Detect Parathyroid Gland Health During Endocrine Surgery

Vanderbilt researchers have designed a laser speckle imaging device to detect parathyroid gland viability during endocrine surgery, during which otherwise healthy parathyroid glands are prone to devascularization leading to long-term hypocalcemia. Currently, the surgeon must use his or her best judgement regarding the health of the parathyroid gland. This technology removes the guess work from the decision and provides a real-time assessment of the parathyroid viability.

Peripheral Nerve Catheter Advancer

A Vanderbilt clinician has developed a device capable of allowing a single practitioner to control both the needle and the catheter while using an ultrasound probe to place a nerve block. A nerve block involves the placement of anesthetic and other agents onto or near a nerve in order to temporarily disrupt the signal traveling along the nerve. To place a nerve block, a needle is inserted into the patient and a catheter is thread through the needle to inject the block. An ultrasound probe is used to identify placement of the catheter and nerve block. Current catheter advancement techniques require one clinician to hold the needle and control the catheter while a second person maneuvers the ultrasound probe to accurately deliver the nerve block. The proper placement of the nerve block is highly dependent on the coordination between the two individuals. Relying on a second individual can result in misplaced nerve blocks or prolong the placement process. The novel catheter advancer eliminates the need for a second clinician and makes the placement faster and more accurate.

Automated Inflatable Binder to Counter the Effects of Orthostatic Hypotension

Vanderbilt scientists have developed an automated inflatable abdominal binder that can detect when a patient moves from a prone or sitting positon to a standing position and automatically apply a sustained servo-controlled compression pressure in order to counter the effects of OH. The binder is as effective as conventional drug therapy in controlling OH, without subjecting patients to potentially harmful side effects and interactions with other medications.

Image-Guided Radio Frequency Ablation

The Biomedical Modeling Laboratory at Vanderbilt University has produced a method and apparatus for use during the collection and processing of physical space data during image-guided surgery. This technology provides a complete system for performing tissue ablations that includes a spatial probe, an ablation tool, and a computer processor. Using this technology, the surgeon is able to view the location of the ablation tool in the patient's medical images as well as the ablation zone of the instrument and the particular portion of the tissue to be ablated.

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.

Method for Non-Invasive Complete Vascular Occlusion Using MR Guided Focused Ultrasound Surgery

Researchers have developed a non-invasive method for creating vascular occlusions at specific locations within a vessel using magnetic resonance guided focused ultrasound (MRgFUS). The speed and efficacy of this approach is better than traditional vascular occlusion methods, and the method can be further enhanced through the use of phase shift nano-droplets. The approach is even applicable to large vessels that can be extremely challenging to ablate due to the heat sink effect. Ultimately, the ability to occlude selected vasculature could aid in the treatment of vascular malformations, hemorrhage control, and tumor devascularization.

Non-Invasive Bacterial Identification for Acute Otitis Media using Raman Spectroscopy

Vanderbilt researchers have developed an optical-based method for real-time characterization of middle ear fluid in order to diagnose acute otitis media, also knows as a middle ear infection. The present technique allows for quick detection and identification of bacteria and can also be applied to other biological fluids in vivo.
