Manufacturing review: the device history record review was performed for the reported lot number and this lot meets all release criteria.The manufacturing review did not indicate any possible manufacturing issue that could be related to the reported event.Investigation summary: the device was returned for evaluation.The image is that of the life stream device returned.It shows the distal section of the device where the stent is present on the balloon and the shaft section connected to the balloon.In the background a coiled section of the shaft is visible.A pinch (highlighted as a red outline in the image) is noted on the shaft close to the proximal bond.The pinch damage matches that of the returned device.The investigation is confirmed for the reported material deformation issue.There were two pinches noted on the outer, one at the exit of the strain relief and the other at the proximal bond.It is likely that handling or user related issues during the removal of the sleeve during device preparation contributed to the event.The investigation was unconfirmed for the reported device incompatibility issue.Although slight resistance was felt when passing through the pinch in the proximal area, a 0.035" guidewire was successfully passed through the device during the evaluation.The definitive root cause for the reported issues could not be determined based upon information received from the field communications, image review and device evaluation.Labeling review: the instructions for use for the life stream product was reviewed and contains the following information relevant to the reported event: potential adverse events ¿ covered stent deformation / kink / fracture directions for use site access and preparation 1.Using standard techniques access the artery and place an introducer sheath or guiding catheter of appropriate inner diameter and a 0.035" (0.89 mm) guidewire across the target lesion.The catalog number identified in section d4 has not been cleared in the us but is similar to the life stream that are cleared in the us.The pro code and 510k number for the life stream is identified in d2 and g5.(expiry date: 11/2021),h6(method: 3331) the information provided by bd represents all of the known information at this time.Despite good faith efforts to obtain additional information, the complainant / reporter was unable or unwilling to provide any further patient, product, or procedural details to bd.
