As reported, during an interventional procedure of the left popliteal artery involving an (b)(6) male patient with a history of bilateral lower extremity stents and below-the-knee amputation of the right leg, a flexor raabe guiding sheath separated at the shaft.Access was obtained in the right common femoral artery for a left popliteal intervention.The patient's anatomy was reported to be tortuous, calcified, and scarred; however, resistance was not reported.The sheath was reportedly in place for two to two-and-one-half hours prior to removal.As the device was being removed, it began to "break into pieces".The dilator was not in place at the time of removal and separation; however an unknown manufacturer's guide wire was in the lumen at the time of separation.The device was able to be removed by hand.An unknown manufacturer's atherectomy device and balloon were used during the procedure.The patient's outcome has been reported as "good".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.

Investigation/evaluation: reviews of the complaint history, device history record, drawing, documentation, instructions for use (ifu), manufacturer¿s instructions, quality control, and a visual inspection of the returned device were conducted during the investigation.The visual inspection of the returned package confirmed that the device was returned in two segments.The first segment was comprised of the check-flo adapter and two pieces of sheath connected by inner coiling.The first piece of sheath was approximately 30cm.From there, a portion of coiling was connected to another 12cm piece of sheath tubing.The second section was also comprised of two sheath portions.The first sheath section was 11cm followed by inner coiling and an additional 31.8cm of sheath tubing.There was biomatter present on the device.There were multiple hemostat marks on either side of both segments.Specifically, there were five sets of hemostat marks on the second portion of the sheath.These marks were indicative of difficult removal.Additionally, a document based investigation evaluation was performed.There is no evidence to suggest the product was not made to specifications.A review of the device history record showed no nonconforming events which could contribute to this failure mode.It should also be noted there were no other reported complaints for this lot number.Furthermore, reviews of the manufacturer¿s instructions, drawings, and quality control procedures were conducted, and no gaps were discovered.Moreover, an ifu is provided with the device which recommends reinserting the dilator prior to removal to decrease the risk of the device separating.Based on the information provided and the examination of the returned product, investigation has concluded that a root cause for this event cannot be traced to the device but to the patient¿s condition and unintended use error.Reportedly, the target vessel was tortuous, calcified, and scarred.Additionally, the dilator was not reinserted prior to removal.We will continue our monitoring of similar complaints and have notified the appropriate personnel of this event.Measures are being conducted to address this failure mode.Per the quality engineering risk assessment no further action is required.This report is required by the fda under 21 cfr part 803.This report is based on unconfirmed information submitted by others.Neither the submission of this report nor any statement made in it is intended to be an admission that any cook device is defective or malfunctioned; that a death or serious injury occurred; or that any cook device caused or contributed to; or is likely to cause or contribute to a death or serious injury if a malfunction occurred.
