Reports come from manufacturers, hospitals and patients and are not verified by the FDA. A report does not prove the device caused the event. Widely used products collect more reports, so totals can't be used to compare products or estimate failure rates. Only reports that name a model's exact device identifier are counted.

• InjuryJul 30, 2026Human-Device Interface Problem

  It was reported that the patient implanted with an Inflatable Penile Prosthesis (IPP) experienced scrotal pain when operating the Momentary Squeeze (MS) pump. A surgical procedure was performed, during which no device issue was identified. Although the pump continued to inflate the IPP as intended, its use caused significant pain to the patient. The physician noted difficulty when manipulating the MS pump and elected to replace it with a Tenacio pump. The new pump was implanted in a different scrotal pocket. In addition, a capsule believed to be contributing to the patient's pain was excised. No additional patient complications were reported.
