2012-182 – Lung cancer is the leading couse of cancer deaths in the United States. Lobectomy is the gold standard extent of resection for most lung cancers, but some patients are poor candidates for lobectomy due to poor pulmonary health/function and/or other comorbities. Sublobar resection, the removal of less than a lobe of the lung, is a compromise procedure for these patients in that it allows for... Read More
A Time Dependent Device for Segmental Whole Gut for Lumina & Mucosal Microbial Swab Sampling by Anatomic Location
2012-169 – Swabs from the middle portions of the gastrointestinal tract are currently very difficult to obtain due to the limitations of current techniques such as endoscopy. Understanding the biology of these regions can potentially have a large impact on the overall health of both people and animals through the effect of the GI tract on other parts of the body. Mayo Clinic investigators have... Read More
2012-156 – We have developed a novel technique for in-vivo genome editing using TALENs
2012-153 – The practice of radiology is a non-linear process where image processing and routing decisions for best practice are often done by humans on the fly. Commercial PACS and image processing workstations assume a fixed workflow that is enshrined in their database schemas, and may only account for 4-5 stages in the lifetime of a diagnostic imaging study. DEWEY uses DICOM (with proposed expansion... Read More

2012-070 – Extraction of chronically implanted leads from pacemakers and defibrillators is difficult because the leads become scarred into position. Several tools are being developed to separate leads from scar tissue. However, a major challenge is the inability to “grip” or “grab” the lead to apply traction for removal. Proximal traction results in the lead uncoiling, as leads do not accommodate... Read More
2012-057 – Shear wave is used to evaluate tissue visco-elasticity, which are sensitive biomarkers of pathology. In order to obtain a 2D ultrasound elastography, an ultrafast imager with a FRAME rate of several kHz is required to capture the fast moving shear waves. This is not feasible with traditional ultrasound imagers with a frame rate of less than 100 Hz where 2D images are formed LINE BY LINE. ... Read More
