Physician Resources

Bioresorbable scaffolds (BRS) are transforming treatment options for patients with coronary artery disease. REVA is committed to supporting the field of bioresorbable scaffolds through product design, technology development, clinical evidence, and physician education.

Why BRS?

Coronary stents are implanted during PCI procedures to restore blood flow and support the vessel while it heals. Once the vessel is healed, the stent is no longer necessary.

Bioresorbable scaffolds are designed to restore blood flow, support the artery through the healing process, and then disappear (or “resorb”) from the body over a period of time. This resorption is intended to allow the return of natural movement and function to the artery.

Comparison of Metallic DES versus BRS

Metallic DES Bioresorbable Scaffolds (BRS)
Implant Procedure Restore blood flow Restore blood flow
Vessel Healing & Recovery Support the vessel during healing Support the vessel during healing
Long-term Heart Health Permanent metallic implant:

  • Annual increase in adverse events of ~2% per year1
  • ~3% stent fracture rate2
  • Interfere with repeat PCI or coronary artery bypass surgery
  • Interfere with non-invasive imaging such as CT Angiography and MRI
Resorption and restoration:

  • Uncage vessel
  • Return of vasomotion
  • Natural movement of artery
  • Retain treatment options
