PhysioCurve design

for implantable cardiac defibrillators (ICDs)

Transvenous ICDs

Benefits of the contoured PhysioCurve™ design for transvenous ICDs include:

  • Reduction in overall skin pressure by 30% versus noncontoured, transvenous devices1
  • Enhanced patient comfort2
  • Improved cosmetic appearance of the implant site3
  • Minimal pocket preparation for replacement procedures4–6

Aurora EV-ICD™ device

Alert Indications, Safety, and Warnings

The Aurora EV-ICD system is an extravascular implantable cardioverter defibrillator that features PhysioCurve design for patient comfort. With its PhysioCurve design, the Aurora EV-ICD system showed a 27% average reduction in tissue pressure relative to the subcutaneous ICD across the three implant locations modeled.7

  • Tapered at the head and bottom of device to reduce tissue pressure and promote patient comfort.
  • Smaller footprint for a smaller incision.
