Modeling of mechanical phenomena in the platinum-chromium coronary stents

Clinical utility of platinum chromium bare-metal stents in coronary heart disease

Coronary stents represent a key development for the treatment of obstructive coronary artery disease since the introduction of percutaneous coronary intervention. While drug-eluting stents gained wide acceptance in contemporary percutaneous coronary intervention practice, further developments in bare-metal stents remain crucial for patients who are not candidates for drug-eluting stents, or to ...

Comparison of Novel Zotarolimus-Eluting Cobalt-Chromium Stents and Everolimus-Eluting Platinum-Chromium Stents in Patients of the Randomized DUTCH PEERS Trial Presenting with Acute Myocardial Infarction

Background: Historically bare metal stents were considered standard of care for STsegment elevation acute myocardial infarction (STEMI). There is limited data on STEMI patients treated for primary angioplasty with ResoluteTM zotarolimus-eluting stent (R-ZES) and the everolimus-eluting stent (EES). Methods: The global RESOLUTE program enrolled STEMI patients in 4 trials: RESOLUTE-All Comers (RAC...

synthesis of platinum nanostructures in two phase system

چکیده پلاتین، فلزی نجیب، پایدار و گران قیمت با خاصیت کاتالیزوری زیاد است که کاربرد های صنعتی فراوانی دارد. کمپلکس های پلاتین(ii) به عنوان دارو های ضد سرطان شناخته شدند و در شیمی درمانی بیماران سرطانی کاربرد دارند. خاصیت کاتالیزوری و عملکرد گزینشی پلاتین مستقیماً به اندازه و- شکل ماده ی پلاتینی بستگی دارد. بعضی از نانو ذرات فلزی در سطح مشترک مایع- مایع سنتز شده اند، اما نانو ساختار های پلاتین ب...

Mechanical behavior of fully expanded commercially available endovascular coronary stents.

The mechanical behavior of endovascular coronary stents influences their therapeutic efficacy. Through computational studies, researchers can analyze device performance and improve designs. We developed a 1-dimensional finite element method, net-based algorithm and used it to analyze the effects of radial loading and bending in commercially available stents. Our computational study included des...
