NxStage PureFlow-B Solution Bags Perimeter Seal Failure Risk

NxStage Medical Inc is recalling NxStage PureFlow-B Solution bags nationwide due to potential perimeter seal failure on the small chamber, which could cause electrolyte fluid to splash into the user's face when opening the peel seam to mix chambers before treatment.

What this means for you

Real risk of harm even if no illness or injury has been reported yet. Stop using the product and follow the agency's guidance.

Our severity reasoning: This is an FDA Class II recall for a medical device with a risk-of-harm defect (potential facial splash injury from fluid); no reported illnesses or injuries are stated in the source, making the hazard theoretical but not low-risk enough for Moderate.
