A Variable Stiffness Catheter Controlled with an External Magnetic Field

Dario Floreano, Alice Tonazzini

Remote magnetic navigation of catheters is a technique used to perform radiofrequency ablation of heart tissue in order to treat cardiac arrhythmias. The flexible magnetic catheters used in this context are in some cases not sufficiently dexterous to navig ...

Nonlinear analysis of right atrial electrograms predicts termination of persistent atrial fibrillation within the left atrium by catheter ablation

Jean-Marc Vesin, Adrian Luca, Andréa Buttu, Etienne Pruvot

The termination of long-standing persistent atrial fibrillation (LS-pAF) can be achieved by stepwise catheter ablation (step-CA) within the left atrium (LA). Our study aims to applying complexity measures derived from nonlinear time series analysis in orde ...

Experimental Testing of AF Septal Modeling Results

Adrian Luca

Introduction: Moving to clinical validation is an essential phase with every model-based result. However, this translation is often not straightforward because animal models differ from human computer models in many anatomic and electrophysiologic ways, wh ...

Our study aims at determining whether the efficiency of step-wise catheter ablation (step-CA) of persistent atrial fibrillation (pAF) can be tracked using organization indices based on the harmonic components of atrial ECG signals until pAF termination. EC ...

Introduction: We hypothesized that organization indices based on the analysis of atrial ECG harmonic components may help identify patients (pts) with persistent AF (pAF) unresponsive to pulmonary vein isolation (PVI) and left atrial (LA) ablation. Using ad ...

Ablation device and method for subsurface biological tissue ablation

Demetri Psaltis, Jae-Woo Choi, Alexandre Goy, Thomas Jean Victor Marie Lanvin

The present invention relates to a subsurface laser-induced optical breakdown (LIOB) ablation system including an optical source for providing optical pulses and an optical waveguide for guiding the optical pulses to a subsurface target biological tissue s ...
