(b)(4).Complaint verification testing could not be performed as no sample was returned for analysis and no damage could be confirmed from the customer provided photo.The instructions-for-use (ifu) provided with this kit warns the user, "do not apply excessive force in placing or removing catheter or guidewire.Excessive force can cause component damage or breakage.If damage is suspected or withdrawal cannot be easily accomplished, radiographic visualization should be obtained, and further consultation requested." a device history record review was performed, and no relevant findings were identified.Without the device to evaluate, the complaint could not be confirmed, and the probable cause could not be determined from the available information.Teleflex will continue to monitor and trend for reports of this nature.

Qn#(b)(4).The customer returned multiple components of a hemodialysis kit, including one guide wire assembly, arrow raulerson syringe (ars), introducer needle and catheter for analysis.Signs of use in the form of biological material were observed on the guide wire.Visual analysis revealed that the guide wire contained multiple kinks towards the distal end of the body.The distal j-bend was misshapen but intact.Microscopic examination confirmed the damage.The distal and proximal welds were full and spherical.No defects or anomalies were observed with the ars.The major kinks on the guide wire measured 511mm, 542mm, and 568mm from the proximal weld.The guide wire total length measured 601mm, which is within the specification limits of 596mm-604mm per the guide wire product drawing.The guide wire outer diameter measured 0.843mm, which is within the specification limits of 0.838- 0.877mm per the guide wire product drawing.The returned ars was attached to the returned 18ga introducer needle.The guide wire was then passed through the subassembly.The undamaged portion of the guide wire was able to pass with no resistance.Minor resistance was encountered at the kinks; however, the guide wire was able to completely pass through the subassembly.Performed per ifu statement, "advance guidewire into arrow raulerson syringe approximately 10 cm until it passes through syringe valves or into introducer needle.".A manual tug test confirmed that the distal and proximal welds were secure and intact.A device history record review was performed, and no relevant findings were identified.The ifu provided with the kit, "do not apply excessive force in placing or removing catheter or guidewire.Excessive force can cause component damage or breakage.If damage is suspected or withdrawal cannot be easily accomplished, radiographic visualization should be obtained and further consultation requested." the report of a kinked guide wire was confirmed through complaint investigation.Visual analysis revealed that the guide wire was kinked towards the distal end.Resistance was experienced during functional testing due to the kinking.Despite the damage, the guide wire met all relevant dimensional requirements, and a device history record review did not reveal any relevant findings.Based on the customer report and the sample received, unintentional use error likely caused or contributed to this event.Teleflex will continue to monitor and trend on reports of this nature.
