Drug Elutable Microspheres


Because experience matters

Terumo Interventional Oncology Division presents LifePearl, a precise answer to a challenge in interventional oncology. LifePearl are PEG (polyethylene glycol) embolization microspheres that can be loaded with chemotherapeutic agents (such as Doxorubicin, Irinotecan, Idarubicin and Epirubicin).

LifePearl offers:

  • Wide range of drug loading options1
  • Enhanced suspension characteristics2, 4, 5
  • Tight calibration3, 4, 5
  • Syringe presentation


LifePearl® microspheres are designed to actively absorb drugs into their matrix2

  • 37.5 mg of Doxorubicin per 1 ml of LifePearl® microspheres
  • 5mg of Idarubicin per 1ml of LifePearl® microspheres
  • 25mg of Epirubicin per 1ml of LifePearl® microspheres
  • 50.0 mg of Irinotecan per 1 ml of LifePearl® microspheres

LifePearl® has a tight calibration which may lead to a more targeted embolisation

LifePearl® offers longer time in suspension than:

  • DC Bead and HepaSphere when loaded with Doxorubicin4
  • DC Bead and Tandem when loaded with Irinotecan5

Longer time in suspension allows smoother embolization procedure without the need for interruption to resuspend the microspheres
