(b)(4).Investigation - evaluation: a review of the complaint history, device history record, documentation, instructions for use (ifu), specifications and quality was conducted during the investigation.The device is shipped with an instruction for use (ifu) that describes the intended use, specific items are addressed such as: "due to thin wall construction, extreme care must be exercised during manipulation and withdrawal.Catheter insertion through a synthetic vascular graft should be avoided whenever possible." additionally, "if resistance is encountered during manipulation, stop and determine the cause before proceeding any further." images were provided and the review of the images indicated that the pigtail of the catheter fractured.From the provided images, there was no evidence to suggest inefficient shaft to tip bonding.The complaint device was not returned, therefore; no physical examinations could be performed.However, a document based investigation evaluation was performed.Review of device history record shows no nonconforming events which could contribute to this failure mode.Based on document review, there is no evidence to suggest the product was not manufactured to specifications.The description of the event notes that, "the physician was pulling with more force than he thought was needed and figured that it was caught on solid plaque and nicked the catheter which caused it to keep separating." returned images also show the tip fragment is within close proximity to a previously implanted stent.It is possible that excess force, patient condition, and/or the stent contributed to this failure mode.However, without the benefit of this returned product, the root cause of this event is unable to be determined with certainty.We will continue to monitor for similar complaints.Per the risk assessment no further action is required.

It was reported during an angioplasty procedure, the physician was pulling the pigtail catheter with force up and over the bifurcation area and thought the catheter was caught on solid plaque and nicked the catheter.The force reportedly caused the catheter to keep separating in the middle section of the catheter.The physician was able to put a snare over the wire and snare the piece of catheter out of the patients anatomy.The physician reportedly believed the separation was due to "excessive calcium." a section of the device did not remain inside the patient¿s body.The patient did not require any additional procedures due to this occurrence.According to the initial reporter, the patient did not experience any adverse effects due to this occurrence.
