Event or Problem Description
The patient reported some healing scabs at the incision site on (b)(6) 2026.The patient attended an incision check appointment on (b)(6) 2026.It was noted that the wound looked like it had been picked at and the surrounding site was dirty.An explant procedure was performed on (b)(6) 2026 due to fear of infection and antibiotics were prescribed.The implanting clinician does not believe the reported issue was caused by the curonix device or surgical implementation.
Additional Manufacturer Narrative
The surgical issue questionnaire was reviewed for potential causes of the reported issue.Based on this review, implanting the device after the expiration date, not prepping the surface of the skin with an antiseptic solution, not irrigating the incision site with an antibiotic solution before closure, improperly closing the surgical site, multiple tunneling attempts, using incorrect tools, and not prescribing antibiotics pre-operatively have been ruled out.However, the implanting clinician believes the reported issue is due to the patient's hygiene, cleanliness, or the wound being picked by the patient.\ \ a curonix representative conducted a review of sterilization and packaging records for the respective product lot; curonix has confirmed that the product was delivered sterile, validated sterilization parameters were used, and sterile barriers were verified to be intact following packaging.\ \ the stimulator is used to treat pain.The cause of the reported issue is due to patient non-compliance due to the patient's hygiene and cleanliness (user error-patient).\ \ rates reviewed at the most recent complaint trending meeting do not indicate a significant increase in surgical issues.Surgical issue rates remain acceptably low; thus, a capa is not required at this time.Surgical issue rates will continue to be tracked and trended.
