FDA Class I recall: potential distal tip detachment in the Harmony delivery catheter, distributed worldwide including Japan (Medtronic)
The U.S. FDA classified the Medtronic Harmony Delivery Catheter System as a Class I recall, its most serious category, because devices built with inner shaft assemblies from specific manufacturing lots may have an increased potential for distal tip detachment. The recall covers 1,881 units distributed worldwide, including Japan.

Key points
- The FDA classified it Class I, its most serious category (Z-2624-2026, reported July 8, 2026, status ongoing).
- The recall covers 1,881 units of the Medtronic Harmony Delivery Catheter System (GTIN 00763000341367; affected lots listed in the record).
- The defect is an increased potential for distal tip detachment in devices with inner shaft assemblies from specific manufacturing lots.
- FDA records limit the description to certain procedural or anatomical conditions rather than universal occurrence.
- Distribution spans U.S. nationwide plus many countries including Japan, Germany, France, Canada and India.
1What Harmony and its delivery catheter are
Harmony is known as a transcatheter pulmonary valve (TPV) system — a way of placing a pulmonary valve using a catheter rather than open surgery. The delivery catheter system is not the valve itself but the instrument used to carry the valve through the vessels to the target position and deploy it.
In heart valve therapy, how safely the valve is delivered matters as much as the valve's own performance, which makes the delivery instrument a component tied directly to the outcome.
2The conditions under which the tip can detach
The defect here is that devices containing inner shaft assemblies from specific manufacturing lots may have an increased potential for the distal tip to detach from the delivery system. FDA records describe this as occurring under certain procedural or anatomical conditions — that is, not in every case, but where factors such as the curvature of the route or an individual patient's vascular and cardiac anatomy combine.
3Why this is the most serious class
If part of an instrument separates inside the body, an additional procedure may be needed to retrieve it, which is why the FDA assigned its most serious category, Class I. At 1,881 units the quantity is not large for a device recall; given the field in which Harmony is used, the affected patient population is correspondingly narrow, so the weight per case is high.
4Why it matters
The explicit inclusion of Japan in the distribution list carries direct meaning for readers outside the United States. FDA enforcement records are published by a U.S. regulator, but when an affected product circulates internationally, the distribution list in the record becomes the starting point for responses in each country.
Because identification rests on lot numbers (GTIN 00763000341367), reconciling stock against the lot list enumerated in the original record is the practical next step.
Why it matters
In heart valve therapy the reliability of the delivery instrument shapes outcomes alongside the valve itself. This case is one where lot-level manufacturing variation surfaced as the possibility of part of an instrument separating inside the body. The 1,881-unit quantity is limited, but distribution reaching many countries including Japan makes lot-level inventory reconciliation and the speed of cross-border information flow the practical priorities for hospitals and distribution networks.
