Abstract

Et kateter omfattende et første flertall av utvidbare forbindelsesledninger (100) og et andre flertall av utvidbare forbindelsesledninger (102) som er adskilt og som ligger i avstand i den langsgående retning fra det første flertall for å levere energi til en hul anatomisk struktur, som en vene, en eggleder, en hemorroide, en spiserøråreknute, for å effektivt å ligere strukturen. Hver forbindelsesledning omfatter en elektrode som er plassert ved den distale ende av den respektive elektrodeforbindelsesledning. Polarisering av forbindelsesledningene kan velges for å oppnå den ønskede kraftfordeling. Hver elektrodeforbindelsesledning omfatter en utoverbøyning slik at når en bevegelig mantel (108) beveges ut av kontakt med forbindelsesledningene, vil disse utvides utover til apposisjon med en indre vegg i strukturen som skal ligeres. Høyfrekvensenergi kan tilføres fra forbindelsesledningene for å tilveiebringe en oppvarmingseffekt i det omkringliggende vev i den anatomiske strukturen. Diameteren til den hule anatomiske strukturen reduseres av oppvarmingseffekten, og elektrodene beveges fritt innover av den krympede strukturen mens de fortsatt opprettholder apposisjon ved den indre veggen av den krympende strukturen.
