Dialog+ Hemodialysis System

Device Use

The Dialog+ Hemodialysis System is a machine used in the treatment of chronic kidney disease for patients whose own kidneys are no longer healthy enough to filter their blood of wastes and excess fluid. These systems are used in hospitals, health centers, and in outpatient dialysis center settings.

Reason for Recall

B. Braun Medical Inc. is recalling the Dialog+ Hemodialysis System due to cracks in conductivity sensors that may allow air to enter into the solution (dialysis fluid or dialysate) used to help filter waste and other excess fluids in the blood. The presence of air in dialysis fluid may lead to improper blood filtration, causing serious adverse health consequences, including death.

Who May be Affected

  • Patients who are undergoing hemodialysis therapy using this device
  • Health care professionals using this device for conduct hemodialysis therapy
