Event Description

Information received from the healthcare professional (hcp) via manufacturer representative (rep) reported lead migration in the tunnel.There was a report of a migration of the lead to extension connector into the tunneling path leading from future implantable neurostimulator (ins) pocket site towards the extension exit site.The physician had to ask for a fluoroscopy support and had to make a new incision in order to open the connection.The patient had a second incision and it took extra or time for the physician.It concerned a brand new product and the root cause needs to be found.The event seemed to be a result of the new product construction/connection from lead to percutaneous extension and/or new tunneling technique.The new dilator tip was sued for tunneling.Other actions taken was support by fluoroscopy and a new incision.The issue was resolved and a surgical intervention occurred.Additional information received reported that the implant date of the lead was on (b)(6) 2020 and the implant of the ins was on 2020-02-07.In the meantime, it seems that the carrier tip widened the tunnel, which might have caused the migrations.The physician took out the percutaneous extension.In addition, the physician would fix the connection at the pocket in the future.Additional information received reported that the contributing factors was most likely the new tunneling technique in which the carrier tip widens the tunnel that caused migration.In the previous system, one would tunnel the twistlock connection, the tunneling route therefore was smaller than the size of the connection piece.There was no issues in the past with old tunneling techniques.The size of the pocket site was as small as possible, the lead and extension were coiled neatly, and the excess cable was coiled neatly plus fixed with bandages.
