Computer simulation of a novel technique for Radio-Frequency Ablation of ventricular arrhythmias
… in the heart. A common treatment for VT is Radio-Frequency Ablation (RFA), which is minimally invasive, but requires maintenance of VT until the target site for ablation is determined. Most patients with VT cannot tolerate this maintenance phase due to hemodynamic instability and for those …

A device user interface for the guided ablative therapy of cardiac arrhythmias
Radio Frequency Ablation (RFA) of cardiac arrhythmias involves the guidance of an ablation catheter to the site of the arrhythmia and the administration of a high-intensity radio-frequency current to the tissue. The current technique used to locate the arrhythmic site suffers from a number of …

Advances in real-time thoracic guidance systems
… applications include radiation therapy, radio frequency ablation, lung/liver biopsies, and brachytherapy seed placement. Recent efforts have made highly accurate sub-mm 3D localization of discrete points available via electromagnetic: EM) position monitoring. Technology from Calypso …

Improving the safety and efficacy of bimodal electric tissue ablation.
Introduction: Bimodal electric tissue ablation (BETA) is a new method of ablation, which combines the process of electrolysis with radiofrequency ablation (RFA) to increase the size of tissue ablations. The cathode of the electrolytic circuit is connected to the radiofrequency (RF) electrode to …

Augmentations vs. Restoration: A computational study of the effects of bacterial sodium channels on cardiac conduction.
… While ectopic triggers can be dealt with via radio frequency ablation, structural causes of arrhythmia, such as microscale source-load mismatches, do not have available treatments. Augmentation of cardiomyocytes with exogenous sodium channels such as Nav1.4 or prokaryotic voltage-gated sodium …
