What to Do

Do not use affected products. No additional actions are required for patients with a successfully implanted Harmony TPV.

On May 28, 2026, Medtronic sent all affected customers a letter recommending the following actions:

• Immediately quarantine and return the affected products to Medtronic.
• Share the Medtronic notification with implanters of the affected products within your organization and their teams. If any of the affected products have been forwarded from your facility to another facility, please notify the other facility about the Medtronic notification.
• Because the potential tip detachment is limited to the Harmony DCS during delivery of the Harmony TPV, there are no additional actions required for patients with a successfully implanted Harmony TPV. These patients should continue to be monitored according to each practice’s standard clinical follow-up procedures.

Reason for Recall

Medtronic stated that certain lots of the Harmony DCS used for insertion of the Medtronic Harmony TPV have an increased risk of distal tip detachment. Detachment of the distal tip during the implant procedure will require a secondary intervention to remove the tip, either by endovascular retrieval or surgical intervention. Additional potential patient risks associated with this issue may include prolonged procedure time, extended fluoroscopy time, occlusion, tissue damage, pulmonary regurgitation, embolism, and hemorrhage. This issue does not involve the Harmony TPV.

As of May 14, 2026, Medtronic has not reported any serious injuries or deaths associated with this issue.

Device Use

The Harmony DCS is a single use, intravascular, over-the-wire delivery catheter incorporating a loading system. It is used in a catheterization lab to facilitate placement of the Harmony TPV within a patient's anatomy. The Harmony TPV System is indicated for use in the management of pediatric and adult patients with severe pulmonary regurgitation who have a native or surgically repaired right ventricular outflow tract and are clinically indicated for surgical pulmonary valve replacement.
