Abstract

Σε συμφωνία με τη παρούσα εφεύρεση, παρέχεται ένας νάρθηκας (στεντ) για εισαγωγή μέσα σε ένα αγγείο ενός ασθενούς. Το στεντ είναι ένα σωληνοειδές στοιχείο που έχει ένα πάχος και που έχει πρόσθιο και οπίσθιο ανοικτό άκρο και ένα διαμήκη άξονα που εκτείνεται μεταξύ τους. Το στοιχείο έχει μία πρώτη μικρότερη διάμετρο για εισαγωγή μέσα στο αγγείο, και μία δεύτερη μεγαλύτερη διάμετρο για έκπτυξη μέσα στο αγγείο. Το σωληνοειδές στοιχείο περιλαμβάνει μία πληθώρα από ελικοειδώς προσανατολισμένες συνεχείς παρακείμενες στεφάνες που εκτείνονται μεταξύ του πρόσθιου και του οπίσθιου άκρου. Οι στεφάνες έχουν μία πληθώρα από διαμήκη υποστηρίγματα όπου έκαστο έχει αντίθετα άκρα και ένα κέντρο μεταξύ τους, όπου τα άκρα των υποστηριγμάτων είναι διαμορφωμένα ώστε να σχηματίζουν μία πληθώρα βρόχων που συνδέουν παρακείμενα υποστηρίγματα στα άκρα των υποστηριγμάτων. Το σωληνοειδές στοιχείο έχει ακραίους βρόχους και στο πρόσθιο και το οπίσθιο άκρο του, όπου οι ακραίοι βρόχοι σε κάθε άκρο είναι ουσιαστικά ευθυγραμμισμένοι μεταξύ τους κατά μήκος ενός επιπέδου το οποίο είναι ουσιαστικά κάθετο στον διαμήκη άξονα.
