Resolute Onyx™ drug-eluting stent is optimised for complex PCI
Overview
Left Main PCI
Optimised for left main and other extra-large vessels
- Complex, left main (LM) PCI can be associated with periprocedural complications and restenosis.
- Successful LM revascularisation requires a stent that can expand under stress without compromise.
Resolute Onyx DES at 6.0 mm maximum expansion†
Resolute Onyx DES' 4.5 and 5.0 mm diameters:
- Expand to 6.0 mm† for optimal deployment with even scaffolding1
- Provide the sustained radial strength needed to handle the left main artery’s elasticity1
SYNERGY MEGATRON™* DES
at 6.0 mm
SYNERGY MEGATRON DES' post-dilatation to 6.0 mm causes the struts to straighten as they approach their expansion limit.

EBC Main study2
Resolute Onyx is the only DES with randomised data supporting provisional and dual-stent strategies in LM bifurcation PCI.
- First randomised trial based on European Bifurcation Club (EBC) Consensus, comparing a provisional to a planned dual-stent strategy in LM bifurcation PCI
- 467 patients with true LM bifurcation disease enrolled in Europe
- Resolute Onyx DES was chosen because of its 4.5 and 5.0 mm diameters, which now expand to 6.0 mm†
Results
- Primary endpoint (death, MI, TLR) showed numerically fewer serious adverse events in the provisional arm (14.7%) versus the dual-stent arm (17.7%)
- Provisional arm showed significantly shorter procedure duration and fluoroscopy time
For reference only in markets where the Resolute Onyx coronary stent and the 0.25 mm expansion have been approved.
Bifurcation PCI
Optimised for bifurcation PCI
- Bifurcation stenting is complex and associated with a high risk of stent thrombosis and restenosis.3
- Main branch optimisation without compromising the side branch requires a flexible stent that can facilitate the passage of a secondary device across a broad range of techniques and anatomies.
Resolute Onyx DES' single-wire design increases flexibility and conformability for optimal strut apposition, which reduces arterial injury and thrombus formation.1

Smooth side branch access
- Other drug-eluting stents feature irregular cell shapes which may obstruct wire or catheter advancement through the cell’s opening.
- Resolute Onyx DES has round struts to create a smooth passage when accessing the side branch while lowering the propensity to catch,1 as seen in the corresponding video from our Bifurcation Exploration website.
- The Bifurcation Exploration website features five techniques performed with Resolute Onyx DES inside an isolated and reanimated beating porcine heart.
- Medtronic created this resource with the EBC and The Visible Heart™ Lab.

Small Vessel PCI
Optimised for extra-small vessels
- Diseased, extra-small coronary arteries with diameters between 2.0–2.25 mm are encountered frequently and, despite size, may require treatment.
- Resolute Onyx is available in a 2.0 mm size with the lowest crossing profile of any DES, making it ideal for treating extra-small vessels.1
- Single-wire design gives it a fluid range of motion and provides the flexibility needed for best-in-class deliverability, helping to reach distal, highly occluded, extra-small vessels.1
- 2.0 mm expands to 3.50 mm† with minimal foreshortening for tapered and extra-small vessels.1
- Resolute Onyx DES demonstrated 2% target lesion revascularization and 0% stent thrombosis in a complex, small-vessel population.4

1-month DAPT in HBR Patients
Optimised for HBR patients who may require 1-month dual antiplatelet therapy (DAPT)
- Up to 40% of patients are at high bleeding risk while 20% may need to interrupt or discontinue DAPT earlier than prescribed.5,6
- To be confident with this decision, a fast-healing stent that’s proven in this patient population is important.
- Resolute Onyx DES is conformable for superior strut apposition.1
- BioLinx™ biocompatible polymer provides superior thromboresistance.7
- Optical coherence tomography (OCT) data showed 90% strut coverage at 30 days, proving fast healing which may enable a shorter DAPT duration8 and providing the foundation for the Onyx ONE Global Trial.
- Onyx ONE Global Trial studied real-world, high bleeding risk (HBR) patients on 1-month DAPT treated with a Resolute Onyx DES or a BioFreedom™* DCS.
- Results showed that Resolute Onyx DES was safe and effective in HBR patients on 1-month DAPT.9
