[3] TEC/NM, Instituto Tecnológico de Ciudad Madero, Ciudad Madero, Tamaulipas, México

In Mexico there is a decline in the production of oil deposits due to the lack of effective treatment of oil emulsions, which generate a problem in the reinjection of emulsified water, transport of oil with high water content and corrosion in the oil refineries. Through the simulation ... Mehr lesen

Design of Radio-Frequency Ablation Catheter

R. Kapuganti,
HCL Technologies, Chennai, India

Radiofrequency (RF) ablation is a treatment modality that kills unwanted tissue by heat. RF ablation is now the treatment of choice for certain types of cardiac arrhythmia. During RF ablation, an electrode is inserted into, or steered intravascularly to the target tissue region under ... Mehr lesen
