(b)(4).The customer returned one opened cvc kit with a guide wire assembly , dilator, and catheter, for evaluation.Visual examination revealed the guide wire was unraveled from the proximal weld and was kinked in multiple locations.The distal j-bend was intact.Microscopic examination of the guide wire confirmed the core wire was broken adjacent to the proximal weld.Both welds were present and appeared full and spherical.The major kinks in the guide wire body was measured at 275mm and 375mm from the distal tip.The core wire measured 598mm in length, which is within the specification of 596-604mm per guide wire product drawing; therefore no pieces of the core wire appear to be missing.The outer diameter of the guide wire measured 0.855mm which is within the outer diameter specification of 0.838-0.877mm per guide wire product drawing.Functional inspection could not be performed due to the damage to the guide wire.A manual tug test confirmed that the distal weld was intact.A device history record review was performed, and no relevant findings were identified.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." the report that the guide wire unraveled was confirmed through examination of the returned sample.The core wire was broken adjacent to the proximal weld.The guide wire met all dimensional requirements during investigation testing.No manufacturing defects were found during this investigation.Arrow guide wires of this size are designed and manufactured to withstand a tensile force of 2.75 pounds force.The selected insertion site and patient anatomy may present a tortuous path that could contribute to the possibility of guide wire kinking.Guide wire breakage may occur if a force greater than the design specification is applied during removal.Based on these circumstances, unintentional use error caused or contributed to this event.Teleflex will continue to monitor and trend for reports of this nature.
