It was reported that: when the physician was inserting the peel away sheath into the upper arm of the patient, resistance was encountered.When the sheath was removed it was noted that the tip of the sheath was deformed, and the body had crumpled.Another sheath was used to complete the procedure successfully.The patient was reported as fine post the incident.

(b)(4).The report of a damaged peel-away body was confirmed through complaint investigation of the returned sample.The customer returned one peel-away sheath with dilator assembly for analysis.Signs-of-use in the form of biological material were observed on the sheath body.Visual analysis revealed that the sheath body and the sheath tip were crimped/folded.White stress marks were also observed.No other defects were observed on the sheath nor the dilator.The crimping on the body measured 41mm-57mm via calibrated ruler from the tabs.The sheath body length measured 2 13/16" via calibrated ruler, which was within the specification limits of 2 5/8"-2 7/8" per the sheath with dilator product drawing.The sheath outer diameter measured 0.099" via calibrated caliper, which was within the specification limits of 0.093"-0.099" per the sheath extrusion product drawing.The sheath inner diameter at the proximal end measured 0.076" via calibrated pin gauge, which equals the nominal value of 0.076" per the sheath extrusion product drawing.The dilator outer diameter measured 0.073" via calibrated caliper, which was within the specification limits of 0.073"-0.075" per the dilator extrusion product drawing.Functional inspection was performed per ifu statement, "check peel-away sheath placement by holding sheath in place, twist dilator hub counterclockwise to release dilator hub from sheath hub, withdraw guidewire and dilator sufficiently to allow blood flow".The returned dilator was able to be removed and re-inserted through the sheath with little to no issue.Manufacturing unit confirmed that the damage likely occurred due to force applied by the customer during insertion.The ifu provided with th e kit informs the user, "do not withdraw dilator until sheath is well within vessel to reduce risk of damage to sheath tip".The ifu also states, "do not use excessive force when introducing guidewire, peel-away sheath over tissue dilator, or tissue dilator as this can lead to vessel perforation and bleeding".A device history record review was performed, and no relevant findings were identified.Based on the customer report, the sample received, and the comments from manufacturing, unintentional use error likely caused or contributed to this event.Teleflex will continue to monitor and trend for reports of this nature.
