“…Several designs of the former stents have been tested and include Palmaz-Schatz [85,160], Roubin [155], Strecker [148,184], Wiktor [13], Freedom [199], Cordis [90], ACS multi-link [178] and others; PalmazSchatz stents are the most commonly used stents in clinical practice, to date. Among the self-expandable stents, Wallstent [156,188] and the Nitinol InStent [9] have been tested. The Wallstent, because of its thrombogenicity and intimal proliferative response, is no longer favored [156,188].…”
