Chandrasekaran, Vinay ; Genin, Guy ; Hafez, Daniel ; Hartquist, Chase ; Leuthardt, Eric ; Lowe, Halle ; Osbun, Joshua ; Zayed, Mohamed
T-019184

— An interdisciplinary team at Washington University has developed an easy-to-use neurovascular catheter system designed to reduce surgery time and prevent herniation during transradial interventions for stroke, aneurysms and other conditions. This device, called “String Theory”, can be sw…

ACALADE: surgical device designed for faster, safer lumbar discectomy
Johnson, Tim ; Leuthardt, Eric ; Moran, Daniel ; Reynolds, Benton ; Stoev, Ivan ; Wright, Neill
T-016236

— Technology Description A team of researchers at Washington University have developed ACALADE (Advanced Capability Lumbar Discectomy), a device designed to help surgeons safely access and quickly remove the back portions of herniated discs for faster, lower risk lumbar discectomy. Currently, about…

SPARTA – A Stent for Fusiform Aneurysms that Prevents Endoleaks
Bayly, Philip ; Derdeyn, Colin ; Elbert, Donald ; Genin, Guy ; Leuthardt, Eric ; McCoy, Kathleen ; Suh, JunWoo ; Teh, Yuni ; Vemuri, Chandu ; Zhao, Alan ; Zipfel, Gregory
T-015969

— Background: Popliteal artery aneurysms are the most prevalent type of peripheral aneurysms and are treated surgically to prevent rupture. Currently, surgical options include open surgery or endovascular aneurysm repair (EVAR). EVAR is less invasive than open surgery, resulting in shorter hospital st…

Cloonan, Paige ; Kamath, Ashwin ; Leuthardt, Eric ; MacEwan, Matthew ; Moore, Amy ; Moran, Daniel ; Qin, Yidan (Ida) ; Ray, Wilson ; Zhang, Christopher
T-017895

— Technology Description A team of researchers at Washington University have developed “SIMPEL”, a small, implanted electrode device designed to manage a variety of conditions (such as asthma, hypertension or neuropathy) by delivering current from a defined, fixed position near specific …

Steerable Thermoablation Probe for Improved Access to Brain Lesions
Leuthardt, Eric
T-015768

— Technology Description An interdisciplinary team led by Professor Eric Leuthardt has developed a steerable device that can be integrated into existing thermoablation systems to treat abnormal brain lesions. Thermoablation is a more targeted and less disruptive method for treating lesions than chem…

Rotoscope – A Self-Cleaning Endoscope
Genin, Guy ; Leuthardt, Eric ; Margolis, Daniel ; Somers, Thane ; Yarbrough, Chester
T-016245

— Technology Description: Drs. Eric Leuthardt and Guy Genin have devised a medical device designed for faster and safer endoscopic surgeries. During these surgeries, the camera lens of the endoscope can become obscured with blood, fog and debris. This slows down the procedure, as the surgeon has to r…

Non-invasive Technology Enables Brain Tumor Biopsy Without Surgery
Chen, Hong ; Dunn, Gavin ; Leuthardt, Eric ; Petti, Allegra
T-017113

— Background: The American Brain Tumor Association reports that about 80,000 of the estimated 700,000 Americans that live with a brain tumor have been diagnosed in 2017. The surgery required for a traditional brain tumor biopsy entails making a hole in the skin and skull, placing a needle probe, and r…

Software to predict low back pain from brain imaging
