Computational modeling of internally cooled wet (ICW) electrodes for radiofrequency ablation: Impact of rehydration, thermal convection and electrical conductivity

Trujillo Guillen, Macarena; Bon Corbín, José; Berjano, Enrique (Taylor & Francis, 2017)

[EN] Purpose: (1) To analyse rehydration, thermal convection and increased electrical conductivity as the three phenomena which distinguish the performance of internally cooled electrodes (IC) and internally cooled wet ...
Electrical-thermal performance of a cooled RF applicator for hepatic ablation with additional distant infusion of hypertonic saline: In vivo study and preliminary computer modeling

Romero-Méndez, Ricardo; Tobajas, Pilar; Burdío Pinilla, Fernando; González, Ana; Navarro Gonzalo, Ana; Grande, Luis; Berjano, Enrique (Taylor & Francis, 2012)

Purpose: The Cool-tip electrode is one of the most widely employed applicators in radiofrequency (RF) hepatic ablation. Previous research demonstrated that it is possible to enlarge coagulation volume when the single ...
Electrophysiological and Structural Remodeling in Heart Failure Modulate Arrhythmogenesis. 1D Simulation Study

Gómez García, Juan Francisco; Cardona, Karen; Romero Pérez, Lucia; Ferrero De Loma-Osorio, José María; Trénor Gomis, Beatriz Ana (Public Library of Science, 2014-09-05)

Background: Heart failure is a final common pathway or descriptor for various cardiac pathologies. It is associated with sudden cardiac death, which is frequently caused by ventricular arrhythmias. Electrophysiological ...
Electrophysiological and Structural Remodeling in Heart Failure Modulate Arrhythmogenesis. 2D Simulation Study

Gómez García, Juan Francisco; Cardona, Karen; Martínez, Laura; Saiz Rodríguez, Francisco Javier; Trénor Gomis, Beatriz Ana (Public Library of Science, 2014-07-23)

Background: Heart failure is operationally defined as the inability of the heart to maintain blood flow to meet the needs of the body and it is the final common pathway of various cardiac pathologies. Electrophysiological ...
In Silico Modelling to Assess the Electrical and Thermal Disturbance Provoked by a Metal Intracoronary Stent during Epicardial Pulsed Electric Field Ablation

González-Suárez, Ana; Pérez, Juan J; O Brien, Barry; Elahi, Adnan (MDPI AG, 2022-12)

[EN] Background: Pulsed Electric Field (PEF) ablation has been recently proposed to ablate cardiac ganglionic plexi (GP) aimed to treat atrial fibrillation. The effect of metal intracoronary stents in the vicinity of the ...
Transección hepática sin suturas mediante un nuevo instrumento asistido por radiofrecuencia. Modelado teórico, estudio experimental y ensayo clínico

Martinez-Serrano, MA; Grande, Luis; Burdío, Fernando; Berjano, Enrique; Poves, Ignasi; Quesada, Rita (Elsevier Doyma, 2011-03)

[ES] El instrumento ideal para realizar la transección hepática debería aunar en una sola herramienta hemostasia segura y rápida. Presentamos nuestra investigación multidisciplinar encaminada al desarrollo de un dispositivo ...
