Claims (14)
1. Medicinsk indretning omfattende: en kirurgisk nål (12); og en langstrakt sutur (14), der har en første ende (14a) fastgjort til den kirurgiske nål (12) og en anden ende (14b) placeret væk fra den kirurgiske nål (12), hvor den langstrakte sutur (14) inkluderer en rørformet maskevæg (16), en hul kerne (18) inden i den rørformede maskevæg (16), hvor den rørformede maskevæg definerer en flerhed af porer (20), der strækker sig igennem den rørformede maskevæg (16), kendetegnet ved at mindst nogle af porerne har en porestørrelse, der er større end eller lig med cirka 500 mikrometer, således at porerne (20) er indrettet til at muliggøre vævsintegrering igennem den rørformede maskevæg (16) af suturen (14), når indført i et legeme.
2. Den medicinske indretning ifølge krav 1, hvor den rørformede maskevæg (16) af suturen (14) strækker sig langs helheden af suturen (14) mellem den første og anden ende (14a, 14b).
3. Den medicinske indretning ifølge et hvilket som helst af de foregående krav, hvor porestørrelsen er en af: (a) i et område på cirka 500 mikrometer til cirka 4 millimeter, (b) i et område på cirka 500 mikrometer til cirka 2,5 millimeter, (c) i et område på cirka 1 millimeter til cirka 2,5 millimeter, (d) cirka 2 millimeter, eller (e) varierende i størrelse.
4. Den medicinske indretning ifølge et hvilket som helst af de foregående krav, hvor suturen (14) har en diameter i et område på cirka 1 mm til cirka 10 mm.
5. Den medicinske indretning ifølge et hvilket som helst af de foregående krav, hvor suturen (14) er ensartet i diameter langs dens helhed.
6. Den medicinske indretning ifølge et hvilket som helst af de foregående krav, hvor suturen (14) er konstrueret af et materiale valgt fra gruppen bestående af: polyethylen-terephthalat, nylon, polyolefin, polypropylen, silke, polymerer af p-dioxanon, co-polymer af p-dioxanon, ε-caprolacton, glycolid, L(-)-lactid, D(+)-lactid, meso-lactid, trimethylen-carbonat, polydioxanon-homopolymer, og kombinationer deraf.
7. Den medicinske indretning ifølge et hvilket som helst af de foregående krav, hvor suturen (14) er radialt deformerbar, således at suturen (14) antager en første tværsnitsprofil i fraværet på lateral spænding og en anden tværsnitsprofil i tilstedeværelsen af lateral spænding, hvor eventuelt den første tværsnitsprofil udviser radial symmetri, fortrinsvis med en cirkulær tværsnitsprofil, og hvor eventuelt den anden tværs nits prof i I udviser delvist eller fuldkommen kollapset konformering.
8. Den medicinske indretning ifølge et hvilket som helst af de foregående krav, yderligere omfattende et anker (22) fastgjort til den anden ende (14b) af suturen (14) til at forhindre suturgennemtrækning under anvendelse, hvor ankeret (22) har en dimension, der er større end en diameter af suturen (14), hvor ankeret (22) kan omfatte en sløjfe, en kugle, en skive, en cylinder, en modhage og/eller en krog.
9. Den medicinske indretning ifølge et hvilket som helst af de foregående krav, hvor den rørformede maskevæg (16) omfatter et vævet eller strikket maskemateriale.
10. Den medicinske indretning ifølge et hvilket som helst af de foregående krav, hvor den hule kerne (18) inkluderer en af et hult cylindrisk rum, en vaffelstruktur, en 3D-gitterstruktur, eller andre egnede matricer, der definerer et eller flere indre tomrum.
11. Fremgangsmåde til fremstilling af den medicinske indretning ifølge et hvilket som helst af de foregående krav, hvor fremgangsmåden omfatter: at danne en rørformet maskevæg (16), der har en flerhed af porer (20) og definere en hul kerne (18), hvor mindst nogle af porerne har en porestørrelse, der er større end eller lig med cirka 500 mikrometer; og at fastgøre en ende af den rørformede maskevæg (16) til en kirurgisk nål (12).
12. Fremgangsmåden ifølge krav 11, hvor at danne den rørformede maskevæg (16) omfatter at danne et rør fra et maskemateriale, væve eller strikke fibre til et rør, og/eller væve eller strikke fibre til et plant lag og efterfølgende at omdanne det plane lag til et rør.
13. Fremgangsmåden ifølge et hvilket som helst af kravene 11 til 12, yderligere omfattende at tilvejebringe et anker (22) på en ende af den rørformede maskevæg (16) modstående nålen (12).
14. Fremgangsmåden ifølge krav 13, hvor at tilvejebringe ankeret (22) omfatter at danne en sløjfe.
