Description

PATENTKRAV 1. Stentaggregat (1) med et rørformet graftmateriale (2) og mindst et rørformet element (3), der har en længderetning og omfatter flere efter hinanden i længderetningen beliggende cylindriske delelementer (4), der er indbyrdes forbundne gennem forbindelses-elementer, kendetegnet ved, at det rørformede graftmateriale (2) på det rørformede element (3) er strækbart i det rørformede elements længderetning (b) . 2. Stentaggregat ifølge krav 1, kendetegne t ved, at forbindelseselementerne (5) holder de cylindriske delelementer (4) i en indbyrdes afstand (c) , når det rørformede element er i en ukomprimeret tilstand med stor diameter, og at graftmaterialet har rundtgående bælgfoldninger (16) i områderne (14) mellem fjederelementerne. 3. Stentaggregat ifølge krav 2, kendetegnet ved, at graftmaterialet (2) er hovedsageligt frit for bælgfoldninger ved fjederelementerne. 4. Stentaggregat ifølge krav 2 eller 3, kendetegnet ved, at afstanden c er beliggende i intervallet fra 2,5-100%, hensigtsmæssigt fra 5-30%, af det rørformede legemes diameter i fuldt ekspanderet tilstand. 5. Stentaggregat ifølge et af kravene 1-4, kendetegnet ved, at graftmaterialets tråde (11) forløbende i det rørformede elements længderetning (b) er af tekstureret garn, mens dets tråde (10) forløbende i det rørformede elements omkredsretning er af et lige garn og begrænser det rørformede elements største diameter i dettes ukomprimerede tilstand. 6. Stentaggregat ifølge et af kravene 1-5, kendetegnet ved, at forbindelseselementerne (5) er af mere fleksibelt fjedermateriale, fortrinsvis ud- giødet rustfrit stål, end de cylindriske fjederelementer (4) . 7. S tent aggregat ifølge et af kravene 1-6, k e n -detegnet ved, at graften er af et elastisk PTFE-materiale. 8. Stentaggregat ifølge et af kravene 1-7, kendetegnet ved, at det enkelte cylindriske delelement er en siksak-formet endeløs wire, og at det rørformede element fra en radialt komprimeret tilstand med forholdsvis lille diameter er selvekspanderende til en tilstand med større diameter. 9. Stentaggregat ifølge et af kravene 1-8, k e n -detegnet ved, at der mellem det enkelte cylindriske delelement og det i længderetningen efterfølgende cylindriske delelement er mindst tre fjedrende forbindelseselementer (5) . 10. Stentaggregat ifølge et af kravene 1-9, kendetegnet ved, at forbindelseselementerne (5) mellem naboliggende cylindriske delelementer (4) er jævnt fordelte i omkredsretningen.
