(b)(4).Evaluation summary: (b)(4).The device was returned for evaluation with the stent dislodged.The reported inflation issue was confirmed.Partial stent deployment could not be confirmed as the stent was already dislodged from the balloon.Follow-up with the site determined that the stent dislodgement occurred during prep of the device for return.The stent movement was confirmed.Based on visual and functional analysis of the returned device, there is no indication of a product quality issue with respect to manufacture, design, or labeling.The investigation determined that the reported inflation issue and partial deployment appear to be due to the tears noted in the inner member.A conclusive cause for the tears was unable to be determined.A review of the lot history record identified no manufacturing nonconformities.Additionally, a review of the complaint history identified no similar incidents from this lot.Based on the reviewed information, there is no indication the issue was caused by, or related to the design, manufacture or labeling of the device.
