Claims (10)

1. Indretning til endoluminal behandling af et blodkar, omfattende: en fleksibel bølgeleder, der definerer en aflang akse med en proksimal ende, der kan forbindes optisk med en strålingskilde; en distal ende af bølgelederen, der kan modtages i blodkarret og indbefatter mindst to strålingsemitterende overflader, der er udformet til at emittere stråling fra strålingskilden lateralt i forhold til den aflange akse af bølgelederen i et ringformet mønster, der strækker sig aksialt, på en omgivende karvæg; og en afdækning, der er fast fastgjort til bølgelederen og forseglet i forhold dertil, der indeslutter de emitterende overflader deri, og som definerer en gas-bølgeleder-grænseflade, for hver emitterende overflade, hvor stråling kan emitteres lateralt i forhold til den aflange akse af bølgelederen gennem afdækningen på den omgivende karvæg, hvor afdækningen er en hætte (110), der er i det væsentlige transparent i forhold til den emitterede stråling, hvor bølgelederen omfatter en fiber (100) med mindst en keglestub (108), der foran fiberen er sat sammen med et fibersegment med en konisk spids (104) i den distale ende, hvor hver fiber/hvert segment har mindst en kerne og et beklædningslag; og hvor mindst en af de strålingsemitterede overflader med en keglestub omfatter en keglestub (108), hvis vinkel og afkortede overfladediameter er udformet således, at en forudbestemt del af energien fortsætter med at bevæge sig fremad i fibersegmentet i kontakt med keglestubben, og en del udstråles lateralt i forhold til den aflange akse af bølgelederen ved keglestubben (108).
2. Indretning ifølge krav 1, hvor den mindst ene strålingsemitterende overflade med en keglestub (108) omfatter et mellemrum mellem keglestubben og fibersegmentet.
3. Indretning ifølge krav 1 eller 2, hvor mindst en af de strålingsemitterende overflader med keglestub (108) omfatter et yderligere konisk afsnit, der er afkortet og orienteret i bagudrettet retning.
4. Indretning ifølge et af kravene 1 til 3, hvor fiberen med en keglestub (108) og fibersegmentet med en konisk spids (104) er sammenføjet ved kobling af keglen og fibersegmentet inden i afdækningen.
5. Indretning ifølge et af kravene 1 til 4, hvor fiberen med en keglestub (108) og fibersegmentet med en konisk spids (104) er sammenføjet ved sammenklæbning af keglen og fibersegmentet.
6. Indretning ifølge et af kravene 1 til 4, hvor fiberen med en keglestub (108) og fibersegmentet med en konisk spids (104) lateralt er smeltet sammen med afdækningen.
7. Indretning ifølge et af kravene 1 til 6, hvor fiberkernen er fremstillet af silika og er omgivet af et fluoreret beklædningslag, hvor det fluorerede beklædningslag er omgivet af et overbeklædningsafsnit, der består af ren silika, i det væsentlige det samme som fiberkernen.
8. Indretning ifølge et af kravene 1 til 7, hvor fiberen er formet til at forbedre overgangszonens jævnhed mellem udvendig fiber, der er forsynet med kappe, og afdækningen.
9. Indretning ifølge et af kravene 1 til 5, hvor bølgelederen er fremstillet af et enkelt stykke fiber, og afdækningen er fremstillet af silika, der i det væsentlige svarer til det silika, der udgør fiberkernen.
10. Indretning ifølge et af kravene 1 til 9, endvidere omfattende mindst en laserkilde, der tilvejebringer laserstråling af mindst en af ca. 980 nm, ca. 1470 nm og ca. 1950 nm, hver ± ca. 30 nm, ved en effekt på højst ca. 10W, hvor den proksimale ende af bølgelederen er optisk forbundet med den mindst ene laserkilde.
