Promus Premier™

Everolimus-Eluting Platinum Chromium Coronary Stent System

Indications, Safety, and Warnings


Caution

Federal Law (USA) restricts this device to sale by or on the order of a physician.

Indications for Use

The Promus PREMIER Everolimus-Eluting Platinum Chromium Coronary Stent System is indicated for improving luminal diameter in patients with symptomatic heart disease or documented silent ischemia due to de novo lesions in native coronary arteries ≥2.25 mm to ≤4.00 mm in diameter in lesions ≤34 mm in length.

Contraindications

Use of the Promus PREMIER Everolimus-Eluting Platinum Chromium Coronary Stent System is contraindicated in patients with known hypersensitivity to:

  • 316L stainless steel or platinum everolimus or structurally-related compounds the polymers or their individual components (see Section 2..2.2, Primer Polymer and Drug Matrix Copolymer Carrier)

Coronary Artery Stenting is contraindicated for use in:

Patients judged to have a lesion that prevents complete inflation of an angioplasty balloon or proper placement of the stent or delivery device.

Patients with uncorrected bleeding disorders or patients who cannot receive anticoagulation or antiplatelet aggregation therapy (see Section 6.2, Pre- and Post-Procedure Antiplatelet Regimen for more information).

Warnings

To maintain sterility, the inner package should not be opened or damaged prior to use.

The use of this product carries the risks associated with coronary artery stenting, including stent thrombosis, vascular complications, and/or bleeding events.

This product should not be used in patients who are not likely to comply with recommended antiplatelet therapy.

Precautions

General Precautions

Only physicians who have received adequate training should perform implantation of the stent.

Stent placement should only be performed at hospitals where emergency coronary artery bypass graft surgery can be readily performed.

Subsequent stent blockage may require repeat dilatation of the arterial segment containing the stent. The long-term outcome following repeat dilatation of endothelialized stents is not well characterized.

Consideration should be given to the risks and benefits of use in patients with history of severe reaction to contrast agents.

Do not expose the delivery system to organic solvents such as alcohol or detergents.

Care should be taken to control the position of the guide catheter tip during stent delivery, deployment and balloon withdrawal. Before withdrawing the stent delivery system, visually confirm complete balloon deflation by fluoroscopy to avoid guiding catheter movement into the vessel and subsequent arterial damage.

Stent thrombosis is a low-frequency event that current drug-eluting stent (DES) clinical trials are not adequately powered to fully characterize. Stent thrombosis is frequently associated with myocardial infarction (MI) or death. In the clinical trials analyzed to date, differences in the incidence of stent thrombosis have not been associated with an increased risk of cardiac death, MI, or all-cause mortality. Additional data from longer-term follow-up of the PLATINUM clinical trials and analyses of stent thrombosis related to DES are expected and should be considered in making treatment decisions as data become available.

When DES are used outside the specified Indications for Use, patient outcomes may differ from the results observed in the NG PROMUS and PLATINUM pivotal clinical trials.

Compared to use within the specified Indications for Use, the use of DES in patients and lesions outside of the labeled indications may have an increased risk of adverse events, including stent thrombosis, stent embolization, MI or death.

Orally-administered everolimus combined with cyclosporine is associated with increased serum cholesterol and triglyceride levels.

The safety and effectiveness of the Promus PREMIER Stent have not been established in the cerebral, carotid, or peripheral vasculature or in the following patient populations:

  • patients requiring multiple stents
  • patients with prior brachytherapy of the target lesion
  • patients in whom mechanical atherectomy are used in conjunction with the PROMUS Premier stent
  • pediatric patients
  • Patients with vessel thrombus at the lesion site.
  • Patients with coronary artery reference vessel diameters <2.25 or >4.00 mm.
  • Patients with coronary artery lesions longer than 34 mm or requiring more than one Promus PREMIER Stent.
  • Patients with lesions located in the saphenous vein grafts, in the left main coronary artery, ostial lesions, or lesions located at a bifurcation.
  • Patients with diffuse disease or poor flow distal to the identified lesions.
  • Patients with tortuous vessels (>60 degrees) in the region of the obstruction or proximal to the lesion.
  • Patients with a recent acute myocardial infarction where there is evidence of thrombus or poor flow.
  • Patients with in-stent restenosis.
  • Patients with moderate or severe calcification in the lesion or a chronic total occlusion.
  • Patients with 3 vessel disease.
