Abstract: Biomedical images of both anatomical structure and real-time changes in neuronal, metabolic, positional, and vascular function in humans and animals is described. Ultra-wideband (UWB) pulse or square wave generators and electrical samplers, implemented using integrated circuits are used to make arrays of miniaturized microwave modules that are placed around the portion of interest in the body or head, allowing images to be made through either time-domain transmission of these pulsed waves through the body, or time domain reflectivity of the waves from internal structures, or their combination. Signal processing separate and extract the time-varying functional information from the static structural image data. The time-varying functional information from certain brain regions can be interpreted in order to control prosthetics, Brain-Machine-Interfaces and the like.

Abstract: An ablation catheter is equipped with an irrigated tip electrode that can stimulate tissue in, e.g., a renal artery to help identify the location of a renal nerve. High-frequency stimulation of the renal nerve causes a decrease in the blood pressure of the patient thereby indicating that a renal nerve is nearby. The ablation catheter is used to ablate the renal nerve using radiofrequency, ultrasound, microwave energy or cryogenic cooling. Irrigation from the irrigated tip electrode may be used to decrease damage to cells in the wall of the lumen of the renal artery other than the renal nerve, such as the endothelial cells. In order to treat atrial fibrillation an ablation catheter would be used to isolate one or more pulmonary veins.
