Abstract

Erfindungsgemäß ist eine Vorrichtung zum Extrudieren eines strukturierten Extrudats, das in einen menschlichen oder tierischen Körper einbringbar ist, vorgesehen. Diese Vorrichtung umfasst eine Extrusionseinrichtung mit einem Gehäuse, wobei das Gehäuse eine umlaufende Seitenwandung aufweist, die an einem in Produktionsrichtung vorne liegenden Ende mit einer eine Austrittsdüse aufweisenden Düsenwandung und in Produktionsrichtung davor liegend mit einer Pinole versehen ist, wobei der Raum im Gehäuse zwischen der Pinole, der Seitenwandung und der Austrittsdüse einen Extrusionsraum begrenzt und das Gehäuse im Bereich des Extrusionsraumes mit einer Polymerzuführeinrichtung versehen ist. In der Pinole ist zumindest ein sich in Produktionsrichtung erstreckender Führungskanal ausgebildet, um zumindest einen stabförmigen Körper von der Einrichtung zum Zuführen stabförmiger Körper bis in den Extrusionsraum einbringen zu können, wobei der zumindest eine Führungskanal in etwa in geradliniger Flucht zur Austrittsdüse angeordnet ist.
