Abstract

Απορροφήσιμες πολυεστερικές ίνες, ταινιοπλέγματα, και χειρουργικά πλέγματα με βελτιωμένες ιδιότητες χειρισμού έχουν αναπτυχθεί. Αυτές οι συσκευές προέρχονται κατά προτίμηση από βιοσυμβατά συμπολυμερή ή ομοπολυμερή 4-υδροξυβουτυρικού εστέρα. Αυτές οι συσκευές παρέχουν ένα πλατύτερο εύρος ιδιοτήτων in vivo αντοχής συγκράτησης από εκείνες οι οποίες είναι επί του παρόντος διαθέσιμες και έχουν μια μειωμένη τάση να συστρέφονται, στην προτιμητέα υλοποίηση, εξαιτίας της συμπερίληψης σταδίων χαλάρωσης και ανόπτησης μετά από εξώθηση και προσανατολισμό της ίνας. Νήματα παρασκευασμένα σύμφωνα με αυτές τις μεθόδους χαρακτηρίζονται από τις ακόλουθες φυσικές ιδιότητες: επιμήκυνση θραύσης από περίπου 17% έως περίπου 85% (ii) μέτρο ελαστικότητας του Young μικρότερο από 350,000 psi, (iii) αναλογία κόμπου προς ευθύγραμμο (αντοχή κόμπου/αντοχή σε εφελκυσμό) 55-80% ή (iv) φορτίο θραύσης από 1100 έως 4200 γραμμάρια.
