The information provided by bard 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 bard.The following were reviewed as part of this investigation: patient severity, trend analysis, applicable previous investigation(s), sample (if available), and applicable fmea documents.Based on a review of this information, the following was concluded: the complaint of the silicone plug coming out of the t-lock assembly is confirmed, but the cause is unknown.The samples returned included one photo sample of t-lock assembly and part of a stylet with yellow tab.A t-lock assembly and associated stylet was also returned.Visual observation found that the photograph showed the t-lock assembly and stylet in a plastic bag, but little else could be observed.The cap with the septum was separate from the rest of the t-lock assembly, and both were found between two sharp kinks in the stylet (nearly right angle kinks), with another found more distal in the main body of the stylet.Another sharp kink was found in the polyimide tubing.Residue was found in the t-lock assembly, including inside the luer screw and on the male luer component, indicating it had been used.The slider clamp was not engaged, and no clamp mark was visible.It appeared that a clear plastic oversleeve/cover was present at the proximal end of the t-lock, where the septum would normally reside.The sleeve¿s proximal end was not even.It could be seen that this cover took on the shape of the ring on the t-lock body just under the hole for the cap.The cap¿s outer wall had been rolled up such that the septum was residing in a depression.Microscopic observation found no damage to the cap.In addition, the shape of the clear plastic cover on a lab sample comparison powerpicc stylet t-lock was found to be similar in shape.The stylet tip was found to be intact; no segment appears to be missing.Functional testing found that the cap could not be introduced into the t-lock assembly, at least partially because the presence of the clear plastic cover blocked the free movement of the cap.Flushing the t-lock through the extension leg found that the device was patent both through the septum placement orifice and the male luer.The bends in the wire do not appear to be related to this complaint, and while they may have occurred during the procedure, they may have also occurred due to shipping.While the complaint of the silicone plug coming out of the t-lock is confirmed, the cause cannot be determined with the information available.Potential contributing factors include excessive or rapid pulling on the wire through the septum, especially without flushing the catheter, rough handling/manipulation, inadequate tightness of the plastic cover over the cap, and flushing against obstruction, such as kinking, creating a large positive pressure within the t-lock.
