Ventricular assist devices (VADs) require a percutaneous driveline. TETS reduces risk of infection however, tissue heating must be managed. Previous studies correlated power loss, (heat flux) to tissue heating with deep implants. An in vivo swine model was used to correlate heat flux with tissue heating for shallow implant (just under the skin). Power and drive frequencies were varied to determine the impact to tissue heating.

Feasibility of Neurapheresis™ Therapy for Multidrug Resistant Gram-negative Bacterial Meningitis

October 4, 2017 - Duke University Medical Center/Minnetronix Neuro

Pseudomonas, Acinetobacter and Klebsiella are three multidrug resistant (MDR) gram-negative pathogens that pose a threat to human health. Patients in hospitals or nursing homes, and with devices such as intravenous catheters or ventilators are at increased risk of Gram-negative bacterial meningitis (GBM) from these bacteria. GBM manifests when...

In Vitro Characterization of the Neurapheresis™ System for the Treatment of Cryptococcal Meningitis

October 4, 2017 - Duke University Medical Center/Minnetronix Neuro

Cryptococcal Meningitis is caused by Cryptococcus neoformans and is the most common cause of fungal meningitis in adults. Treatment for Cryptococcal Meningitis is based on an induction, consolidation, and maintenance approach with antifungals, but is associated with...

A Novel Therapeutic Approach for Cryptococcal Meningitis

October 26, 2016 - Duke University School of Medicine/Minnetronix Neuro

Cryptococcal meningitis (CM) is a devastating opportunistic infection that primarily presents in immunocompromised patients. CM is caused when Cryptococcus neoformans, a basidiomycete fungal pathogen, invades the central nervous system (CNS) and circulates within...

User Studies and The Design of a Completely Implantable VAD System

June 24, 2015 - Lucke L, Bluvshtein V, Stoll M, Weiss W. Presentation at ASAIO 61st Annual Conference, Chicago, Illinois, June 24-27, 2015

To eliminate the percutaneous cable currently required for operation of a ventricular assist device, a totally implanted system must be developed. Understanding the required layout and use of the...
