Orsiro Mission Sirolimus Eluting Coronary Stent System
FDA Clearance Information
The Orsiro Mission Sirolimus Eluting Coronary Stent System received FDA PMA clearance on December 21, 2023. Manufactured by Biotronik, it is classified as a Class 3 device.
What It Is
FDA-Cleared Indications
- FDA PMA P170030 includes an update to the maximum post-dilatation diameter specification for the T6S stent design, increasing it from 3.5 mm to 4.0 mm.
- The device is indicated for coronary artery stenting according to its approved labeling.
Clinical Applications
- Percutaneous coronary intervention involving placement of a drug-eluting stent in a coronary artery
- Treatment of coronary artery lesions requiring mechanical vessel support after balloon angioplasty
- Release of sirolimus at the treated coronary lesion to help reduce neointimal growth and restenosis
- Post-dilatation of the T6S stent design up to the FDA-approved maximum diameter of 4.0 mm

Evidence Limitations
Practical Considerations
- The stent is delivered through a catheter, commonly using femoral or radial arterial access, with fluoroscopic imaging guidance.
- The T6S stent design has an FDA-approved maximum post-dilatation diameter of 4.0 mm under the updated specification.
- Patients generally require antiplatelet therapy after placement; the treating cardiologist determines the medication regimen and duration.
- MRI conditions should be confirmed in the current device labeling before scanning. Patients should tell MRI staff that they have a coronary stent.
- Coronary stenting may not be appropriate in patients who cannot receive required antiplatelet therapy or who have a relevant allergy or contraindication to device materials or medications.
