(b)(4).The customer returned one sheath assembly and a bard balloon catheter for evaluation.Visual examination of the returned sheath revealed a small portion of the catheter was extruding through the distal tip.The returned catheter was torn and separated.The catheter contained multiple kinks.Much of the catheter appeared a lighter green, indicating excessive force.A portion of the catheter was pulled out of the sheath and fragments of the balloon were found.The length, outer diameter, and inner diameter of the returned sheath were measured and all were found to be within specification.The outer diameter of the returned bard catheter measured to be 1.665 mm.A device history record review was performed with no relevant findings.The ifu provided with this kit instructs the user, "upon removal of sheath, inspect it to ensure entire length has been withdrawn." the reported complaint of sheath/catheter resistance was confirmed by complaint investigation.The returned bard catheter was broken and separated inside the returned sheath.Removal of the catheter from the sheath revealed fragments of balloon, indicating the catheter was pulled from the sheath while it was still inflated.The returned sheath passed all relevant dimensional testing.A device history record review was performed with no relevant findings to suggest a manufacturing related issue.Based on the sample received, it was determined that operational context caused or contributed to this event.Teleflex will continue to monitor and trend for complaints of this nature.
