What is happening in DXY right now?

DXY (Implantable Pacemaker Pulse-Generator): nothing changed in the six FDA sources we watch.

Checked predicate ancestry, recalls, adverse events, new entrants, review time, crowding. Nothing changed, so there is nothing here — which is the point. We only write when something did.

How long does FDA review take for DXY?

The median FDA review time for DXY is 56 days, measured across the 461 most recent decisions with both a received date and a decision date.

Review time here is decision date minus date received, as published by FDA. It is elapsed calendar time, not FDA review days — the two differ whenever the agency stops the clock for an additional information request.

Are there recalls in DXY?

openFDA lists 75 recall records against product code DXY. A recall record covers one firm's corrective action and may span many device lots.

Showing the 5 most recently initiated of 75. Recall class comes from openFDA's enforcement endpoint, which does not carry every recall — where it is missing, none is shown rather than guessed. Status is FDA's own wording; a terminated recall is a closed one, and the total spans the code's whole history, not just what is open today.

How many adverse events are reported for DXY?

MAUDE holds 2,506 adverse-event reports naming product code DXY, 561 of them received in the last 12 months.

MAUDE reports are submitted by manufacturers, importers, user facilities and the public. They are unverified, and a report is not proof that the device caused the event.

Is adverse-event reporting in DXY unusual?

One month sits above DXY's own expected range: 1 April 2025.

21 months do not have a full, unbroken year of history before them, so no expected range is shown for those. Insufficient history is reported as insufficient rather than as zero: an empty baseline would turn a gap in our data into a spike. Method: ewma_alpha_0.3_sd_2 corpus_adjusted. Counts are divided by the corpus-wide volume for that month before comparison, so a rise across all of MAUDE is not reported as a rise in DXY.

What are the predicate devices in DXY?

FDA publishes no machine-readable predicate field, so no predicate chain is recorded for this code yet.

A predicate chain matters because a device inherits the safety history of what it was compared to. FDA publishes the chain only inside each 510(k) summary PDF, never as data — so where we have edges, they are read from those documents, and where we do not, we say so instead of showing an empty list.
