Abstract
Przedstawiony na rysunku stent samorozprężalny charakteryzuje się tym, że ma budowę zamknięto-komórkową na końcach i otwarto-komórkową w środku; w których to częściach w sekcji zamknięto-komórkowej wszystkie oczka stentu łączą się z sąsiadującymi, natomiast w sekcji otwarto-komórkowej jedynie część oczek łączy się z sąsiednimi. Sekcja otwarto-komórkowa powstaje poprzez połączenie elementów w kształcie litery V w okrąg na kształt korony, a następnie poszczególne okręgi tworząc długość, połączone są co czwartym narożnikiem z narożnikiem okręgu poprzedzającego odmiennie do części zamknięto-komórkowej, gdzie okręgi tworzące długość połączone są z poprzednimi wszystkimi narożnikami; dodatkowo przyrząd na obu końcach w części zamknięto-komórkowej rozszerza się zwiększając swoją średnicę w odniesieniu do części środkowej otwarto-komórkowej.
