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), applicable fmea documents, labeling, and applicable manufacture records.Based on a review of this information, the following was concluded: the complaint of a wire being difficult to insert through a needle is confirmed, but the cause is unknown.The returned device was one guidewire within its hoop (no j-tip), determined to be 0.0175" od x 50cm at preliminary evaluation.One end was floppy, and one was stiff.The most distal few centimeters manifested a variety of bends.A small amount of residue, possibly blood, was found on the guidewire hoop.Microscopic evaluation showed that while the distal tip was intact, the final, most distal coil was displaced such that it was forced outward from the circumference of the wire, though not broken.At a point around 4.5 cm proximal to the distal tip of the guidewire, it was found that some of the coils were stretched such that they were no longer packed tightly but spaced out.Tactual evaluation showed that the displaced coil on the distal tip was noticeable tactually, and showed that the outer coils at the distal end would not move distally when pulled.Functional testing involved attempting to pass the wire through a 21 ga needle.The passage could be accomplished, with a small amount of resistance, in some cases, but not in others.The complaint is confirmed, but the needle's condition and procedural factors may be pertinent to determining the root cause of this event.In addition, the damage to the wire may have either been a consequence of the reported difficulty of insertion or an original cause or contributing factor thereto.It is possible that the guidewire was retracted against the needle, causing tensile damage to the coils of the guidewire, and then the guidewire was difficult to insert due to catching on the needle or damage related thereto.Difficulty of insertion due to placement technique, etc.May have occurred, either alone or in conjunction with the aforementioned potential contributing factors.The current ifu for the powerpicc solo device states that if the guidewire must be withdrawn while the needle is inserted, the needle and wire should be removed as a unit in order to prevent the needle from damaging or shearing the guidewire.As part of the venipuncture procedure and after insertion of the guidewire, the user is instructed to gently withdraw the safety introducer needle or catheter while holding the guidewire in position.A lot history review (lhr) of 16ab3368 showed no other similar product complaint(s) from these lot numbers.
