Returned for evaluation was one (1) angiographic catheter.The returned catheters tip was detached.The tip shows stretching at the catheter shaft end.The nature of the break indicates possible difficulty in withdrawing the device or interference with the guidewire utilized.Additionally, significant longitudinal scraping along the catheter shaft was noted.Based on the description of the complaint, it may likely be concluded the stretching occurred during the procedure after guidewire insertion.The appearance and nature of the defect is consistent with excessive tensile force application to the tip beyond its elastic range.The cause of this interference cannot be conclusively determined in this case.The customer's reported complaint description of the tip detached from the catheter was confirmed.Tip material is soft and pliable and is not brittle.The root cause of the tip detachment cannot be definitively determined but likely root cause is excessive tensile force applied after guidewire insertion, i.E.Handling damage.This is evidenced by the stretched nature of the failure location.A review of the device history records was performed for the indicated lots for any deviations related to the reported failure mode of the complaint. the review confirms that the lots met all material, assembly and performance specifications; i.E.No ncr associated with reported failure mode.Labeling review: the instructions for use, which is supplied to the end user with this catalog number, contains a statement; "the maximum pressure limit of catheters intended for flush angiography is stated on the catheter package.When using a pressure injector, do not exceed the stated maximum pressure." the ifu also states; "do not attempt to hand straighten the tip of any curved tipped catheters which are furnished with a tip straightener.This may result in damage to the product.Tip straighteners are furnished on all catheters intended to be straightened with the aid of a tip straightener.Reshaping of the catheter tip is not recommended.Physical damage to the catheter material can result when exposed to heat." a review of the angiodynamics complaint system noted no adverse trends for this complaint type and product family.This type of complaint will continue to be monitored for trends.Reference (b)(4).
