Abstract

Przedmiotem wynalazku jest sprężynowy cewnik do badań elektrofizjologicznych i nieodwracalnej elektroporacji serca, który charakteryzuje się tym, że wystający z tulejowego przewodu głównego (1) rdzeń (2) tego cewnika wykonany jest ze stopu metali zachowujących pamięć kształtu, i wygięty jest w kształt stożkowej spirali (7) o zróżnicowanej liczbie zwojów, z których co najmniej jeden wyposażony jest w nałożone na ten rdzeń tulejkowe elektrody (5) zasilane poprzez izolowane przewody elektryczne i oddzielone od siebie tworzywowymi pierścieniowymi elementami (6), przy czym średnica ø1 pierwszego zwoju spirali wynosi od 5 mm do 30 mm, a średnica ø2 ostatniego zwoju spirali wynosi od 10 mm do 31 mm, natomiast długość każdej z tych elektrod (5) wynosi od 2 mm do 4 mm, a średnica ø wynosi od 1 mm do 3 mm, przy czym elektrody te przesyłają impuls o amplitudzie rzędu 100 – 3000 V w czasie i od 5 mikrosekund do 6 milisekund, zaś ilość elektrod (5) rozmieszczona na spirali cewnika wynosi od 10 — 65 sztuk.
