Claims (14)

1. Fremgangsmåde til fremstilling af en medicinsk rørformet genstand, fx et kateter, til indføring i en kropskanal, omfattende følgende trin: ekstrudering af et rør ved skubning af rørmateriale gennem en ekstruderdyse (3); afskæring af det ekstruderede rør i en forudbestemt længde; og fremføring af en initial del af det ekstruderede rør over en spids dorn (4); hvor den spidse dorn (4) er placeret tæt ved ekstruderdysen (3), så der dannes en udfladet ende; og hvor den spidse dorn (4), efter at en forudbestemt længde af det ekstruderede rør er fremført på den spidse dorn (4), føres bort fra ekstruderdysen (3) til hindring af, at resten af det ekstruderede rør ekspanderes af den spidse dorn (4).
2. Fremgangsmåde ifølge krav 1, hvor den spidse dorn (4) forskydes i en retning af ekstruderingen.
3. Fremgangsmåde ifølge krav 1 eller 2, hvor den spidse dorn (4) forskydes med en hastighed, der hovedsagelig svarer til en hastighed, hvormed det ekstruderede rør fremstilles.
4. Fremgangsmåde ifølge ethvert af de foregående krav, omfattende det yderligere trin med fastgøring af den udfladede ende af det ekstruderede rør ved den spidse dorn (4).
5. Fremgangsmåde ifølge ethvert af de foregående krav, hvor det rørformede materiale omfatter mindst ét af monosaccharid, disaccharid, oligosaccharid og polysaccharid.
6. Fremgangsmåde ifølge ethvert af de foregående krav, omfattende det yderligere trin med formning af en ende af røret modsat den udfladede ende til en afrundet spidsdel, hvilken formning fortrinsvis indebærer smeltning.
7. Fremgangsmåde ifølge ethvert af de foregående krav, yderligere omfattende dannelse af en åbning i rørvæggen, hvilken dannelse fortrinsvis omfatter mindst én af udstansning og blanketskæring.
8. Apparat til fremstilling af en medicinsk rørformet genstand, fx et kateter, til indføring i en kropskanal, omfattende: en ekstruderdyse (3) beregnet til at ekstrudere et rør; en ekstruder indrettet til at skubbe rørmateriale gennem ekstruderdysen (3); et skæreorgan (12) til afskæring af det ekstruderede rør i en forudbestemt længde; og en spids dorn (4), hvor den spidse dorn er anbragt tæt ved ekstruderdysen (3), så der fremføres en initial del af det ekstruderede rør på den spidse dorn (4), hvorved der dannes en udfladet ende, og hvor den spidse dorn (4) er forskydelig, så den spidse dorn (4) kan forskydes bort fra ekstruderdysen (3), når en forudbestemt længde af det ekstruderede rør er fremført over dornen (4), for at hindre, at resten af det ekstruderede rør ekspanderes af den spidse dorn (4).
9. Apparat ifølge krav 8, hvor den spidse dorn (4) kan forskydes i en retning af ekstruderingen.
10. Apparat ifølge krav 8 eller 9, hvor den spidse dorn (4) kan forskydes med en hastighed, der hovedsagelig svarer til en hastighed, hvormed det ekstruderede rør fremstilles.
11. Apparat ifølge ét af kravene 8 til 10, hvor den spidse dorn har en konisk eller keglestubagtig form.
12. Apparat ifølge ethvert af kravene 8 til 11, yderligere omfattende et klemmearrangement til fastgøring af den initiale del af det ekstruderede rør til den spidse dorn (4), mens den spidse dorn (4) forskydes bort fra ekstruderdysen (3).
13. Apparat ifølge ethvert af kravene 8 til 12, yderligere omfattende mindst ét af et udstansningsorgan (11) og et afrundet spidsformende organ (13) placeret i nærheden af ekstruderdysen (3).
14. Apparat ifølge ethvert af kravene 8 til 13, hvor ekstruderdysen (3) yderligere omfatter en centralt udragende tap (10), hvor ekstruderdysen (3) er indrettet til at ekstrudere røret over den centralt udragende tap (10).
