What is it? The PROMUS Element Plus and Promus PREMIER stent systems each consists of two components: the stent and the catheter delivery system. The PROMUS Element Plus and Promus PREMIER stents are metal tubes with the drug everolimus contained in a thin coating on the stent’s surface.

The PROMUS Element Plus and Promus PREMIER stents are mounted on a folded balloon attached to a catheter delivery system and placed into a blood vessel (coronary artery)supplying blood to the heart. The stent helps to keep the coronary artery open and it is made of a platinum-chromium metal alloy

The PROMUS Element Plus stent uses the identical drug coating formulation and drug dose density as the approved PROMUS/XIENCE V stent. The PROMUS Element Plus uses the identical stent materials, stent design, and balloon materials as the approved ION stent. The Promus PREMIER System is very similar to the PROMUS Element Plus stent, but has additional metal connector wires in its structure. Due to the extra connectors on the stent there is a very slight increase in the amount of drug on the Promus PREMIER stent.

How does it work?

A catheter with a small balloon mounted on the end is inserted into a blood vessel in the groin or arm and advanced into a coronary artery.
The catheter is then positioned at the narrowed portion of the artery and the balloon is inflated. As the balloon inflates, it stretches the coronary artery wall (a procedure known as balloon angioplasty).
The balloon is then deflated, and the catheter is removed from the artery.
The PROMUS Element Plus or Promus PREMIER stent delivery catheter is then positioned at the narrowing of the coronary artery. The balloon on the stent delivery catheter is inflated, which expands the stent and presses it against the coronary artery wall. This may be followed by repeat balloon inflations within the stent to achieve the desired stent expansion.
The stent remains permanently implanted within the coronary artery to help keep the artery open.
The drug (everolimus) is released over time into the artery wall around the stent to help prevent the vessel from re-narrowing.

When is it used? The PROMUS Element Plus and Promus PREMIER stents are used in patients who have a narrowing in their coronary arteries caused by coronary artery disease – a condition that occurs when the arteries that supply oxygen-rich blood and nutrients to the heart muscle become narrowed or blocked by a gradual build-up of “plaque.” Plaque is made up of fatty deposits (cholesterol), white blood cells, calcium, and scar tissue that collect over time in the coronary artery wall. If these arteries become blocked or narrowed, treatment may be required to improve blood flow and increase the supply of oxygen to the heart.

The PROMUS Element and Promus PREMIER stents are to be used in patients, including those with diabetes, who have narrowing in coronary arteries with length less than or equal to 34 mm with reference vessel diameters greater than or equal to 2.25 mm and less than or equal to 4.00 mm.

What will it accomplish? A significantly narrowed coronary artery limits blood flow to the heart muscle and can cause chest pain (angina). Placement of the PROMUS Element Plus or Promus PREMIER stent within the narrowed coronary artery improves blood flow. After a coronary artery stent is implanted, re-narrowing of the artery may occur. The drug (everolimus) is released over time from the PROMUS Element Plus or Promus PREMIER stent surface into the adjacent artery wall to help prevent re-narrowing of the vessel.

When should it not be used? (Contraindication)
The PROMUS Element Plus or Promus PREMIER Everolimus Eluting Coronary Stent System should not be used in patients who:

Cannot receive antiplatelet and/or anticoagulant therapy
Have a coronary blockage that prevents complete angioplasty balloon inflation or proper placement of the stent or stent delivery system, or
Have known hypersensitivity or contraindication to everolimus or structurally-related compounds, cobalt, chromium, nickel, tungsten, acrylic, and fluoropolymers.
