Spring-loaded catheter for an electrophysiology (ep) study and irreversible electroporation within the heart

A spring-loaded catheter for electrophysiology studies and irreversible electroporation within the heart has a plastic main conduit connected at one end to an electrical connector, from which electrodes located at the other end of the conduit are supplied via electric wires, characterized by the fact that the core protruding from the main sleeve conduit is made of a metal alloy that retains shape memory and is bent in the shape of a conical spiral with a different number of coils, at least one of which is equipped with overlapping on this core, sleeve electrodes fed through insulated electric wires and separated from each other by plastic ring elements, where the diameter Ø1 of the first coil of the spiral ranges from 5 mm to 30 mm, and the diameter Ø2 of the last coil of the spiral amounts to 10 mm to 31 mm, while the length of each of these electrodes is from 2 mm to 4 mm, and the diameter Ø is from 1 mm to 3 mm, where the electrodes which send a pulse with an amplitude of 100-3000V in time and from 5 microseconds to 6 milliseconds, and the number of electrodes located on the catheter spiral is from 10-65 pieces.
