Information Regarding Your Patient ID Card, Team Lead HR Projects, Processes & Reporting, BIOlute bioabsorbable Poly-L-Lactide (PLLA) eluting a limus drug, ø 2.25 - 3.0 mm: 60 μm (0.0024"); ø 3.50 - 4.0 mm: 80 μm (0.0031"). 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. Orsiro. The BIOlute active component is a bioabsorbable polymer matrix combined with a -limus drug that is released in a controlled manner, leaving only the PROBIO-coated stent in the long term. 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. Sirolimus is a macrocytic triene antibiotic that has immunosuppressive and antiproliferative properties and elutes slowly over 4 t… BIOFLOW-III is a global, open-label registry that will enrol 1,000+ patients and will also look at pre-specified subgroups including diabetes, small vessels, acute myocardial infarction and chronic total occlusion. They may also lower your chances of having a heart attack. The force at the proximal hub and the blockage is measured.

The Orsiro device is a hybrid drug-eluting stent that represents a new strategy in the treatment of coronary artery stenosis. Pushability is the force transmitted along the length of the catheter. The mechanical stability is crucial for carrier systems of DES and BIOLute, due to the high strength of PLLA, is providing very good properties. Enrolment is scheduled to start in 2011. The PRO-Kinetic Energy cobalt–chromium stent platform has a double-helix stent design that allows for increased flexibility without compromising scaffolding or fatigue resistance. The biocompatible and gentle degradation is believed to lead to better patient outcomes. Some areas of the website may not work. Lower diffusion of ions also leads to a lower rate of corrosion and a lower risk of tissue inflammation response as a result of allergic reactions.In vitro studies have shown up to a 96 % reduction of allergenic metal ion release when the stent surface is coated with silicon carbide.1,2 PROBIO is well known as it has been used for more than 15 years on all Biotronik-manufactured stents and has been implanted in more than one million patients. 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.

DES are combination products composed of a medicinal product(s) and medical devices and since the medicinal product(s) has an ancillary function to the device they are in accordance with the Council Directive 93/42/EEC 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. Prof Olivier Varenne, MD . 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. The stent will be offered in up to 40mm lengths, making it one of the longest drug-eluting stents on the market. The force required to compress the stent is radial strength. 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.

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). The elution curve is adapted to the therapeutic window of the drug and is in line with that of other -limusbased stents.

Since the introduction of drug-eluting stents (DES), physicians have tried to find a delicate balance between achieving a highly effective result without compromising the safety of the patient. Orsiro has demonstrated consistently low target lesion failure (TLF) in all-comers trials compared to major modern drug-eluding stents (DES). 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. generations of drug-eluting stents (DES) [1,2]. Vascular Intervention // CoronaryDrug-Eluting Stent SystemOrsiro, Clinically provenExtensive clinical program*. Highly deliverableDesigned for challenging cases, the Orsiro stent system provides better push and easier cross with a lower crossing profile. The cobalt– chromium stent material allows for thin struts while maintaining optimal radial strength and radiopacity. Objectives The aim of the present study was to assess the outcome of patients with acute myocardial infarction (AMI) complicated by cardiogenic shock (CS) receiving drug-eluting stents (DES) compared with bare-metal stents (BMS). Correspondence to: Prof Olivier Varenne, Hôpital Cochin, Assistance Publique—Hôpitaux de Paris, 75014 Paris, France. Sirolimus-beschichtete Stents werden in drei größeren randomisierten, doppelblinden Studien mit insgesamt mehr als 1.600 Patienten mit unbeschichteten Stents verglichen.2-4 Indikation für die koronaren Stents bei den im Mittel 60- bis 62-jährigen Patienten sind mittel- bis langstreckige nicht vorbehandelte ("de-novo"-) Stenosen in Koronarien mit kleinem Durchmesser. SES and PES revolutionized rates of restenosis after cardiac procedures. In clinical trials, these reduced re-narrowing cases to less than 10%.

Biodegradable polymer Sirolimus-eluting stents vs. Wessely R, Blaich B, Belaiba RS, et al., Comparative characterization of cellular and molecular anti-restenotic profiles of paclitaxel and sirolimus. To achieve this we use the highly deliverable PRO-Kinetic Energy bare metal stent as a platform for Orsiro. -Hybrid Drug Eluting Stent Indicated for discrete de-novo stenotic lesions and in-stent restenotic lesions. ability to protect the drug from degradation during processes such as sterilisation and during shelf life. The PROBIO passive coating provides a seal on the metal surface of the stent and the BIOlute active coating provides controlled drug release, with both components preventing an increased inflammatory response. Jensen et al. The wedge-shaped transitions at the stent ends allow for scaffolding and flexibility throughout the entire length of the stent. Indicated for discrete de novo stenotic lesions and in-stent restenotic lesions. Longitudinal data refers to … Crossability is the mean resistance (mean force) registered by the stenosis during the complete passage of the stent delivery system. Outcomes associated with drug-eluting and bare-metal stents: a collaborative network meta-analysis. A long-term polymer degradation study evaluating histology and histomorphometry up to three years was performed, demonstrating excellent biocompatibility and a lack of late increase in inflammation (data on file, BIOTRONIK AG, under publication).
