The reported event was confirmed.Received only the catheter for evaluation.The catheter was visually evaluated and it was observed that the inflation lumen was pinched and there was an external dent mark at the location of the pinch.The lumen appeared to have been clamped off.The following functional test was performed: tested using lab syringe, unable to inflate the balloon with 10ml.Instead, the inflation funnel filled with water and ballooned out.Deflated and repeated using quick fill technique and achieved the same result.Manipulate the pinched lumen on the shaft using finger and after few second, no pinch observed.Re-inflated and deflated the balloon with 10ml water and the balloon inflated and deflated without difficulty.Per the dimensional evaluation, the following results were found: pinched inflation lumen 13cm from tip eye snip length 3/32" eye snip width 2/32" eye snip distance from distal cuff 6/32" eye snip distance from proximal cuff 4/32" rubberize thickness 9 thou reinforcement 155 thou inflation funnel thickness 50 thou balloon thickness (average) 25 thou inflation lumen coverage 10thou the evaluation verified that the pinched lumen was the cause of the balloon being difficult to inflate.The pinch was not permanent and can be released.This condition was a result of post manufacturing damage and was not manufacturing related.The device history record was reviewed and found nothing that could have caused or contributed to the reported event.The instructions for use state the following: " [contraindications] 1.Method for use: (1) do not reuse.(2) do not resterilize.(3) this device contains 10% povidone-iodine.For patients with past history of allergic hypersensitivity to povidone-iodine or iodine, consider using alternative disinfectants.(4) be careful that the catheter is not exposed to ointments, contrast medium or oil-based lubricants (including vegetable oils such as olive oil, mineral oils such as white petrolatum and animal oils).[they may damage the device and may burst balloon.] (5) do not hold the device with forceps, etc.Avoid contact with any blades or sharp-edged instruments.[catheter damage may cause balloon rupture and accidental balloon removal or failure to deflate or remove the balloon.] 2.Applicable patients (1) do not use in patients who are or have been allergic to natural rubber latex (2) patients with known allergy to silver coated catheter." (b)(4).
