The coronary stent implantation systems, ARTHOS and ARTHOSInert, enable easier positioning of the stent during interventions. The stainless steel MACplus slotted tube stent with its improved design promises to keep restenosis rates low. The new coronary implantation system ARTHOSInert offers a stent system with an ‘inert’ surface, which specifically addresses the problems of nickel, chromium and molybdenum elution. The special refinement process used produces a stent surface, which blocks ion diffusion from the stainless steel. The combination of the ART balloon catheter with the MACplusInert stent in ARTHOSInert produces a coronary stent implantation system with optimal features for fast and problemfree direct stenting.
Whether sirolimuseluting Bx VELOCITY™ stents represent a turning point in the treatment of coronary artery disease will be determined only after the results of the upcoming large randomized clinical trials, but results from the pilot studies are already very encouraging. The next step will be the application of this new technology for the treatment of more complex situations such as: instent restenosis, ostial and bifurcated lesions, long lesions, total occlusions, saphenous vein grafts, small vessels, main stem stenosis, multivessel disease, in the setting of acute myocardial infarction, peripheral disease, diabetic patients, etc. A pilot investigation testing the feasibility and efficacy of the sirolimuseluting Bx VELOCITY™ stent for the treatment of instent restenosis is already underway at the Institute Dante Pazzanese of Cardiology in Brazil and at the Thoraxcenter in The Netherlands. Results will be available by the end of 2001.
