Waya wa zachipatala wa Nitinol ndi alloy-memory alloy yomwe yagwiritsidwa ntchito kwambiri m'makampani azachipatala chifukwa cha mawonekedwe ake apadera. Waya wa Nitinol amapangidwa kuchokera ku kuphatikiza kwa nickel ndi titaniyamu, zomwe zimapanga zinthu zapamwamba kwambiri zomwe zimatha kupindika ndi kupindika popanda kutaya mawonekedwe ake.
Chimodzi mwazabwino zazikulu za waya wachipatala wa Nitinol ndikutha kukumbukira mawonekedwe ake oyamba. Akatenthedwa pamwamba pa kutentha kwina, waya wa Nitinol umabwerera ku mawonekedwe ake oyambirira, ngakhale atapindika kapena kuponderezedwa. Izi zimapangitsa kuti zikhale zofunikira kuti zigwiritsidwe ntchito pazida zamankhwala monga ma stents, pomwe zimatha kupanikizidwa pakuyika ndikukulitsa mawonekedwe ake apachiyambi kamodzi.
Kuphatikiza pa luso lake lokumbukira mawonekedwe, waya wachipatala wa Nitinol ndiwogwirizananso kwambiri. Izi zikutanthauza kuti sizimayambitsa zovuta m'thupi la munthu ndipo zitha kugwiritsidwa ntchito mosamala muzachipatala popanda chiopsezo chokanidwa kapena zotsatirapo zoyipa.
Waya wa Nitinol ndi wamphamvu kwambiri komanso wokhazikika, ndikupangitsa kuti ikhale chinthu choyenera kugwiritsidwa ntchito pazida zamankhwala zomwe zimafunika kupirira kupsinjika kwambiri komanso kupsinjika. Imalimbana ndi dzimbiri ndipo imatha kupirira kutentha kwambiri, ndikupangitsa kuti ikhale yoyenera kugwiritsidwa ntchito pazamankhwala osiyanasiyana.
Ponseponse, waya wachipatala wa Nitinol ndi chinthu chamtengo wapatali chomwe chimapereka zinthu zapadera zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito pazida zamankhwala. Maluso ake a kukumbukira mawonekedwe, biocompatibility, mphamvu, ndi kulimba kwake kumapangitsa kukhala chinthu chosunthika chomwe chingagwiritsidwe ntchito pazinthu zosiyanasiyana zachipatala, kuchokera ku stents ndi catheter kupita ku zida zopangira opaleshoni ndi zingwe zamano.
