Claims (5)

  1. PAT E NT K RAV
    1. Ballonablationskateter (1) omfattende: et skaft (5, 6), hvori en lumen trænger ind i længderetningen; en ballon (2) fastgjort til skaftet, hvor lumenen kommunikerer med det indre af ballonen; og en højfrekvensstrømpåførende elektrode (3) anbragt inde i ballonen (2), hvilken elektrode er dannet ved at vikle en højfrekvensstrømtiIførende strømførende ledning (8), der tilfører højfrekvensstrøm fra strømforsyningsorganer (7), omkring skaftet, en strømførende temperatursensorledning (9), der tilfører et målt signal til strømforsyningsorganerne, indkapslet mellem den viklede højfrekvensstrø mti Iførende strømførende ledning (8) og skaftet og er fastgjort langs skaftets længderetning; kendetegnet ved, at der er dannet en termisk sensor (4a) med termoelement ved det punkt, hvor den højfrekvensstrø mti Iførende strømførende ledning (8) og den strømførende temperatursensorledning (9), som udgør den højfrekvensstrø mpåfø rende elektrode (3), kommer i kontakt med hinanden for første gang set fra bagendesiden i længderetningen, og den strømførende temperatursensorledning (9) er i kontakt med den højfrekvensstrø mti Iførende strømførende ledning (8) ved en flerhed af punkter.
  2. 2. Ballonablationskateter ifølge krav 1, omfattende en oscillator, der giver oscillation til en opvarmningsvæske i ballonen ved gentaget indsugning og udledning af opvarmningsvæsken fra lumenen.
  3. 3. Ballonablationskateter ifølge krav 1 eller 2, hvor temperatursensoren (4a) med termoelement er dannet ved bagendepartiet af den højfrekvensstrø mpåfø r-ende elektrode (3).
  4. 4. Bal I o n abl ati o n skatete r ifølge et hvilket som helst af kravene 1 til 3, hvor den strømførende temperatursensorledning (9) når forendepartiet af den højfrekvensstrø mpåfø rende elektrode (3).
  5. 5. Ablationskateter ifølge et hvilket som helst af kravene 1 til 4, hvor den strømførende temperatursensorledning (9) og den højfrekvensstrømtiIførende strømførende ledning (8) er dannet af en forskellig type metal.
