The reported event was unconfirmed.Visual inspection noted one temperature sensing catheter was received.Visual evaluation noted the temperature sensing wire was kinked inside the thermistor lumen of the catheter.The drainage lumen was flushed, and no leaks were observed.The catheter balloon was inflated with 5.5 ml methylene blue solution (3 drops 1% aq methylene blue per 100ml distilled water) and balloon concentricity was observed to be 60:40.This meets specification as concentricity should not exceed 70:30.The balloon rested for 30 minutes without leaks and passively deflated without issue or cuffing, returning 5.5 ml of solution.A potential root cause for the reported failure could be inadequate pressure on the machine to punch.A device history record review was not required per the investigation.The instructions for use were found adequate and state the following: " visually inspect the product for any imperfections or surface deterioration prior to use.Recommended inflation capacities 8 fr.And 10 fr.(3cc balloon): use 3.5cc sterile water 12 fr.(5cc balloon): use 5.5cc sterile water 14 fr.And larger (5cc balloon): use 10cc sterile water do not exceed recommended capacities.Warning: after use, this product may be a potential biohazard.Handle and dispose of in accordance with applicable local, state, and federal laws and regulations.Caution: aggressive traction, particularly in the presence of suturing, is not recommended for 100% silicone balloon foley catheters.To deflate catheter balloon: gently insert a syringe in the catheter valve.Never use more force than is required to make the syringe ¿stick¿ in the valve.If you notice slow or no deflation, re-seat the syringe gently.Allow the balloon to deflate slowly on its own.Do not aspirate or manually accelerate the deflation of the balloon.If permitted by hospital protocol, the valve arm may be severed.If this fails, contact adequately trained professional for assistance, as directed by hospital protocol.Should balloon rupture occur, care should be taken to assure that all balloon fragments have been removed from the patient." h11:section a through f - the information provided by bd represents all of the known information at this time.Despite good faith efforts to obtain additional information, the complainant / reporter was unable or unwilling to provide any further patient, product, or procedural details to bd.
