Description
(57) Anotace:
Při způsobu výroby se samoexpanzníbiodegradabilní stent mající strukturu atraumatického pravidelného pletiva z jednoho kusu polydioxanonového monofilního vlákna a po upletení se vystavuje konstantní teplotě v rozmezí od 80 °C do bodu měknutí polydioxanonu.
Způsob výroby samoexpanzního biodegradabilního stentu
Oblast techniky
Vynález se týká způsobu výroby samoexpanzního biodegradabilního stentu, používaného zejména pro implantaci do trubicových orgánů gastrointestinálního traktu, přičemž tento stent má strukturu atraumatického pravidelného pletiva, tvořeného jedním kusem polydioxanonového monofilního vlákna.
Dosavadní stav techniky
V dnešní době jsou pro výrobu samoexpanzních stentu k dispozici plně degradabilní materiály, např. kyselina polymléČná, kyselina polyglykolová, polyglaktin, polydioxanon, polyglykonát apod., avšak stenty z nich vyrobené mají tu nevýhodu, že musejí být expandovány dalším prostředkem, například pomocí balónku, jako je tomu u řešení podle EP 0615769 nebo EP 0761251. Pokud by tyto stenty měly být samoexpanzní, musely by být vyrobeny z degradabilního vlákna velkého průměru nebo z degradabilní trubičky se silnou stěnou. Toto provedení by však vyžadovalo použití zavaděčového systému velkého průměru, což je v přímém rozporu s klinickými potřebami z hlediska bezpečnosti.
Cílem vynálezu je proto nalezení způsobu výroby samoexpanzního stentu, u kterého bude dosaženo větší pružnosti a pevnosti.
Podstata vynálezu
Vytyčeného cíle je dosaženo způsobem výroby samoexpanzního biodegradabilního stentu majícího strukturu atraumatického pravidelného pletiva, tvořeného jedním kusem polydioxanonového monofilního vlákna podle vynálezu, jehož podstata spočívá v tom, že tento stent je pleten z jednoho kusu polydioxanonového monofilního vlákna a po upletení je vystaven konstantní teplotě v rozmezí od 80 °C do bodu měknutí polydioxanonu. Doba tohoto vystavení je odvislá zejména na síle a konkrétních předem zjištěných vlastnostech použitého vlákna. Takto tepelně zpracovaný stent získá vlastnosti, které umožní jeho stlačení a umístění do zavaděčového systému a také jeho následné roztažení po opuštění tohoto systému.
Příklad provedení vynálezu
Byl vyroben samoexpanzní biodegradabilní stent upletením z polydioxanonového monofilního vlákna, který byl po upletení vystaven v peci působení konstantní teploty 100 °C po dobu 20 minut.
