The reported event was inconclusive since no sample was return for evaluation.A potential root cause for this failure mode could be ¿incorrect hub / luer design".The lot number is unknown; therefore, the device history record could not be reviewed.The instructions for use were found adequate and state the following: "bard® reusable woven ureteral catheters manual cleaning and disinfection instructions these devices are supplied sterile and must be cleaned, disinfected, and visually examined prior to each subsequent use.Steam sterilization is not recommended for these devices.Caution: federal (u.S.A.) law restricts this device to sale by or on the order of a physician.Prior to cleaning: use personal protective equipment (e.G.Gloves, gowns, eyewear, face masks or shields, respiratory protection devices) appropriately to protect users from exposure to both chemicals and microorganisms.After use, devices may be a potential biohazard.Handle in accordance with accepted medical practice and applicable local, state, and federal laws and regulations.Between uses, devices should be cleaned manually (includes presoak, rinsing, brushing, and drying), visually examined, and disinfected per the instructions below.Special instructions for 3 fr and 4 fr ureteral catheters: due to the fragile lumen wall, using a syringe with a needle on the 3 fr and 4 fr ureteral catheters is not recommended.Two compatible tuohy borst adapters and luer lock syringes will be required: one for cleaning and one for disinfecting the 3 fr and 4 fr ureteral catheters.Discard the tuohy borst adapters after the cleaning and disinfecting procedures.For more information regarding this type of adapter, call c.R.Bard, inc.Medical services and support at 1-800-227-3357 or email medical.Services@crbard.Com.Manual cleaning: ¿ timing ¿ clean medical devices as soon as practical after use (e.G.At the point of use), because soiled materials become dried or baked on devices making the removal process more difficult.¿ point of use pre-cleaning ¿ remove metal stylet from catheter, if applicable.For flushing the 3 fr and 4 fr ureteral catheters: use a compatible tuohy borst adapter and luer lock syringe to remove excess soil with a liquid flush from the proximal end using cool tap water (maximum 25°c, 77°f).E yelets near the tip shall also be flushed with the tuohy borst adapter and luer lock syringe.The eyelets should be advanced far enough into the adapter to ensure all eyelets are flushed.For all other french sizes: use appropriately sized syringe to remove excess soil with a liquid flush from the proximal end using cool tap water (maximum 25°c, 77°f).Eyelets near the tip shall also be flushed with this syringe.After flushing, brush device for a minimum of one (1) minute with a clean, soft bristle brush of an appropriate size.¿ cleaning ¿ detergent solution preparation - prepare and use an enzymatic detergent solution according to manufacturer¿s instructions.Enzol¿ enzymatic detergent also known as cidezyme¿ enzymatic detergent was validated with these devices using 1 oz per gallon of warm tap water 27°c to 44°c (81°f to 111°f).If using an equivalent enzymatic detergent solution, refer to manufacturer¿s instructions for dilution and water temperatures.Water temperature should not exceed 45°c (113°f for any step of this cleaning process.Presoak and flush - completely immerse devices in the enzymatic detergent solution for a minimum of one (1) minute.While immersed, manipulate devices and use a syringe of an appropriate size to flush detergent solution through the entire length of the lumen.Actuate devices while immersed in the detergent solution to ensure all hard to reach areas are contacted by the detergent solution.For flushing the 3 fr and 4 fr ureteral catheters, use a compatible tuohy borst adapter and luer lock syringe as previously mentioned.Brush ¿ after soaking, use a clean, soft bristle brush of an appropriate size to clean all external surfaces.Flush ¿ for 3 fr and 4 fr ureteral catheters, use a compatible tuohy borst adapter and luer lock syringe to flush the inner lumen with a minimum of 15 ml of detergent solution.Actuate devices while flushing.For all other french sizes, flush devices with a minimum of 50 ml of detergent solution.Actuate devices while flushing.Use a syringe of an appropriate size and diameter.Repeat the flush process two (2) times for a total of three (3) flushes, ensuring all visible soil and debris is removed and all fluid exiting the lumen is clear.If visible soil is detected during the final lumen flush, repeat brushing and flushing steps.Rinsing - step 1: rinse devices thoroughly under running water (sterile or distilled) with a temperature range of 27°c to 44°c (81°f to 111°f) for a minimum of two (2) minutes to remove any residual detergent solution or debris.Step 2: flush ¿ for 3 fr and 4 fr ureteral catheters, flush the inner lumen with a minimum of 15 ml of sterile or distilled water utilizing a temperature range of 27°c to 44°c (81°f to 111°f) using a compatible tuohy borst adapter and luer lock syringe.For all other french sizes, flush the inner lumen with 50 ml of sterile or distilled water utilizing a temperature range of 27°c to 44°c (81°f to 111°f).Use a syringe of an appropriate size and diameter.Step 3: brush - use a clean, soft bristle brush of an appropriate size to brush devices for a minimum of one (1) minute.Step 4: repeat step 2 - flush two (2) times for a total of three (3) flushes.Step 5: immerse devices in fresh water (sterile or distilled) for a minimum of two (2) minutes.While immersed, actuate devices and repeat steps 2 - 4 using fresh water (sterile or distilled).Step 6: air flush (step only required for 3 fr and 4 fr ureteral catheters) - use a compatible tuohy borst adapter and luer lock syringe to flush air" h11: section a through f -
