Finite Element Analysis of Induced Electroosmotic Flow in Brain Tissue and Application to ex vivo Determination of Enzyme Activity
Ectopeptidases are commonly accepted to be a means of clearing active peptides. However, studies have shown that they can also regulate peptide activity. We have developed a technique of electrokinetic push-pull perfusion (Ek-PPP, Figure 1) to examine this largely unexplored mechanism of ... Read More
Transient RF Heating of a Conductive Implant: Coupled Electromagnetic/Thermal Simulation and Experimental Validation
The purpose of this work was to establish a reliable radio frequency (RF) heating simulation which directly provides transient temperatures for medical devices with high geometric fidelity. These temporal results of localized temperatures can be used to determine conditions for safety of ... Read More
