elettrocatetere transesophageal with surface elettrodica tin and implementation according to international safety standards

摘要

there is a elettrocatetere for cardiac stimulation transesofagea that satisfies two main characteristics: 1) catheter with good flexibility.but with the possibility of tightening and driveability during introduction into the esophagus, with correspondence to the safety standards for the ce mark.2) minimizing the phenomenon of polarization electrolytic electrodes to obtain low thresholds for stimulation and recording of cardiac signals.we propose the following solution: - possibility of insertion of a mandrel through a plastic tube inserted into the catheter and independent.in order to be able to collect the conductors into a single piece of wire connected to a multipolar connector with contact female.- the possibility of use of the tube insertion mandrel for the infusion of liquid chemical pharmacology in esophagus.cover the surface of electrode with titanium nitride (tin) to obtain a significant reduction in the polarization electrodes.
