The reported event was confirmed as manufacturing related.One sample was confirmed to exhibit the reported failure.Visual evaluation of the returned sample noted one opened (without original packaging), used temperature sensing silicone foley catheter.Visual inspection of the sample noted solution could not advance into the shaft when trying to inject the catheter with 10 ml methylene blue solution (3 drops 1% aq methylene blue per 100ml distilled water).It could be seen that the shaft drainage lumen and funnel lumen were not continuous, and there were silicone blocking it.This was out of specification per inspection procedure, which states, "check for defects: excessive material (over fill), bubbles/voids, splits and/or blemishes." a potential root cause for this failure could be ¿patient impact, reduced flow rate during use with potential injury to bladder or urinary system".The device history record was reviewed and found nothing that could have caused or contributed to the reported event.The instructions for use were found adequate and state the following: "[warnings] 1.Method for use (1) do not inflate the balloon in the urethra.[the urethra may be injured.] (2) do not pull the catheter hard.[the bladder/urethra may be injured.] 2.Applicable patients ·patients with delirium who might pull out catheter [when patient tugs at catheter unconsciously, the bladder and urethra may be damaged.] [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 patients with known allergy to silver coated catheter." the actual/suspected device was inspected.
