Koven Technology is recalling the BiDop 3 Pocket Doppler packaged with a fetal probe because the product labeling includes a fetal indication for use that is not cleared under its 510(k).

The agency’s classification

FDA (Devices): Class II

Class II is a situation in which use of or exposure to a violative product may cause temporary or medically reversible adverse health consequences, or where the probability of serious adverse health consequences is remote.

This is the agency’s own classification, taken from its notice. The severity score below is our assessment, not the agency’s. How recall classes work

What this means for you

Our assessment, not the agency’s: severity 2/5 (Moderate).

Minor labeling or packaging issue, or a voluntary precautionary recall. Risk of harm is low but real — follow the manufacturer's instructions.

Our severity reasoning: Rubric level 2 covers voluntary precautionary recalls: the recall concerns an indication on the labeling that falls outside the device's clearance, and the source describes no defect or malfunction.
