TCT 2017: BIOTRONIK's Orsiro Drug-Eluting Stent Shows Low Five-Year Event Rates in BIOFLOW-II RCT and BIOFLOW-III Registry 01.11.2017 Medizintechnik Orsiro features a hybrid coating of passive and active components: the PROBIO passive coating seals the metal surface of the stent and prevents interaction with the surrounding blood and tissue, while the BIOlute active coating contains a highly biocompatible polymer that delivers a -limus drug over 12–14 weeks and degrades gently over one to two years, thereby avoiding increased inflammation. To achieve this we use the highly deliverable PRO-Kinetic Energy bare metal stent as a platform for Orsiro. The FDA approved SES and PES for use in patients with newly diagnosed, previously untreated single lesions <28 mm to 30 mm in length and a vessel diameter between 2.5 mm and 3.75 mm. The advanced stent crimping technology provides a low crossing profile (0.99 mm) and the optimised delivery system allows for higher-pressure inflations (mean burst pressure 24–30 atm depending on diameter; rated burst pressure 16 atm). This ensures minimal wall injury, leading to better patient outcomes. Premium Drupal Theme by Adaptivethemes.com.

The Orsiro DES (Biotronik AG, Bülach, Switzerland) is the first hybrid DES, offering a unique hybrid coating consisting of passive and active components. 1 Definition. On Orsiro, a circumferential coating rather than an abluminal coating was chosen to ensure that the polymer adheres to the stent platform even in the areas that face high stress during stent expansion. Synsiro is a hybrid DES solution consisting of passive and active components: Vascular Intervention // CoronaryDrug-Eluting Stent SystemOrsiro, Clinically provenExtensive clinical program*. Comparative claim refers to major drug-eluting stent manufacturers in U.S. market, as well as BIOTRONIK. ability to protect the drug from degradation during processes such as sterilisation and during shelf life. Before expansion of the lesion, the midsection of the stent remains compressed while the outer Crossability is the mean resistance (mean force) registered by the stenosis during the complete passage of the stent delivery system. Aktuelle Daten der BIOSTEMI Studie zeigen dass Patienten, die mit Biotroniks ultradünnem Medikament-beschichteten Orsiro Stent behandelt wurden, nach zwölf Monaten deutlich weniger Fälle von Zielläsion-Versagen (Target Lesion Failure, TLF) dokumentiert wurden als bei Patienten, die mit einem Xience Stent versorgt wurden. After selection of the appropriate polymer, the next critical step in terms of elution kinetics was ensuring a uniform coating of the polymer and drug.5 The homogenous coating of the stent was realised using a unique coating technique. The elution curve is adapted to the therapeutic window of the drug and is in line with that of other -limusbased stents. This, together with the strong mechanical properties of the polymer matrix itself, means that the risk of tearing off the coating as a result of stress during implantation and balloon dilatation is avoided.

Radcliffe Cardiology is part of Radcliffe Medical Media, an independent publisher and the Radcliffe Group Ltd. Percutaneous coronary intervention (PCI) has continued to evolve, from its origins in balloon angioplasty and bare metal stent (BMS) implantation, to the development and application of contemporary drug-eluting stents (DESs). 10.1016/j.ahj.2015.05.009; 7. The PRO-Kinetic Energy, coronary, stent platform is laser cut from a single tube of L-605 cobalt chromium alloy (CoCr). Furthermore, an overlap safety study looking at four-week quantitative coronary angiography and histology showed that there was no difference in safety profile and drug effect in the overlapping region of Orsiro. *. Dual antiplatelet therapy (DAPT) consisting of aspirin and a P2Y 12 in hibitor is prescribed in the treatment of acute coronary syndrome (ACS) or following percutaneous coronary intervention (PCI) for drug-eluting stent (DES) implantation.An important misconception remains that DAPT should be prescribed to prevent stent thrombosis. These stents were developed to prevent the proliferation of smooth-muscle cells and other cell types seen with restenosis. 1.1 Drug-eluting stents are recommended for use in percutaneous coronary intervention for treating stable angina, within their instructions for use, only if: the target artery to be treated has less than a 3-mm calibre or the lesion is longer than 15 mm, and . Kalnins A, Erglis U, Dinne A, et al., Clinical outcomes of silicon carbide coated stents in patients with coronary artery disease, Med Sci Monit, 2002;8:16–20. The new benchmark for DESBIOFLOW-V 12-month clinical outcomes compared to Xience, In a post-hoc analysis of pooled patient-level data from three RCTs, Orsiro achieved a 96.9% probability of superiority* on TLF rate versus Xience.10. All of these features of the double-helix stent design translate into increased trackability, crossability and ability to conform to the vessel wall. 6: The Platinum Plus trial examined the The force at the proximal hub and the blockage is measured. IIB(P)31/2015 – IIB(P)85/2014-2; 16 The stent system is advanced through a stenosis model. In the development of BIOlute, from those polymers meeting the initial screening parameters, the selection was narrowed to focus on the criteria of biocompatibility as measured by local tissue responses in pig coronaries; this led to the selection of Poly- L-Lactidde (PLLA)4 as the polymer matrix of BIOlute. Drug-eluting stent GlobalData expects this to grow at a compound annual growth rate (CAGR) of 3% until 2028. Zilberman M, Eberhart RC, Drug-eluting bioresorbable stents for various applications, Annu Rev Biomed Eng, 2006;8:153–80. -Hybrid Drug Eluting Stent Indicated for discrete de-novo stenotic lesions and in-stent restenotic lesions. In the short term the passive PROBIO coating is covered by the active absorbable polymer coating, but nevertheless PROBIO serves a purpose since ion release can take place through the degrading polymer. 10.1016.S0140-6736(16)31920-1 and presentation at TCT 2016; 2 TLF as a composite of cardiac death, target vessel-related myocardial infarction, or clinically indicated target lesion revascularization; 3 Pilgrim et al. The results also served as input to the design of BIOFLOW-II (ClinicalTrials.gov Identifier: NCT01356888), a pan-European randomised controlled trial with 440 patients comparing the Orsiro with the Xience Prime stent that started enrolment in July 2011. The latest version of BioMatrix, the BioMatrix Flex™, launched in 2010, features a more flexible stent platform for improved deliverability. The XIENCE Sierra™ stent system is indicated for improving coronary artery luminal diameter in patients, including those with diabetes mellitus, with symptomatic heart disease due to de novo native coronary artery lesions (length ≤ 32 mm) with reference vessel diameters of ≥ 2.25 mm to ≤ 4.25 mm. Various concepts have been introduced into the marketplace in the attempt to identify the optimal combination of characteristics; however, until now very little attention has been paid to combining a temporary drug therapy with passivation of the metallic stent that is left in the coronary artery. This combination of effortless deliverability with a hybrid structure opens up a new generation of devices for improved patient outcomes. In sirolimus-eluting stents, ≈80% of the rapamycin has eluted by 30 days, whereas paclitaxel-eluting stents have a biphasic drug release profile in vitro with an initial burst during the first 48 hours after implantation followed by a sustained low-level release for at least 2 weeks. The Lancet 2014.10.1016/S0140-6736(14)61038-2; 4 TLF as a composite of cardiac death, target vessel myocardial infarction, and clinically indicated target lesion revascularization; 5 Jensen et al. While first generation DESs significantly decreased risk of in-stent restenosis observed with BMSs, their use was complicated by late and very late stent thrombosis. Parry TJ, Brosius R, Thyagarajan R, et al., Drug eluting stents: sirolimus and paclitaxel differentially affect cultured cells and injured arteries, Eur J Pharmacol, 2005;524:19–29. Orsiro is supported by a comprehensive clinical programme consisting of a series of trials sharing the family name BIOFLOW. The sirolimus drug load is 1.4 μg/mm2 and the elution is optimised for clinical benefit to 12–14 weeks. We only use information without personal reference (e.g. The current stent of choice is a DES due to the fact that it releases an anti-proliferative drug, which reduces the risk of in-stent restenosis, a common complication of using a bare metal stent. Some areas of the website may not work. The PROBIO coating achieves this passivation through its semi-conductive properties by reducing the interactions of protein/cell constituents with the stent surface. Another advantage of the prolonged gentle degradation seen with PLLA is that it minimises the inflammatory response (see Figure 2). The highly biocompatible polymer gently degrades over one to two years, avoiding increased inflammation and ultimately metabolises into CO2 and H2O via the Krebs cycle. The polymer thickness on the abluminal side of the Osiro device is 7.4 μm, one of the lowest among available DES (see Figure 3). 2006;67(2):181-187. Die Einführung bioresorbierbarer Polymere erscheint vielen hier als der nächste logische Schritt. Medikamentenfreisetzende Stents sind implantierbare Gefäßnetze (), die kleine Mengen bestimmter Arzneistoffe freisetzen. Allerdings gab es beim Endpunkt Stentthrombose einen kleinen, aber signifikanten Unterschied. Olivier Varenne. Adding the polymer to the thin struts of the PRO-Kinetic Energy stent platform, the total thickness of the stent struts of stents with a nominal diameter of up to 3.0 mm is 71 μm – significantly lower than the thickness of competitors, including Xience (Abbott Vascular, Abbott Park, IL, US) at 95 μm and Endeavor Resolute (Medtronic, Minneapolis, MN, US) at 99 μm.
