(b)(4).Evaluation summary: the device was returned and investigated.The reported difficult cds insertion through the hemostasis valve was confirmed.A review of the lot history record revealed no manufacturing nonconformities.Additionally, a review of the complaint history identified no other incidents reported from this lot.The reported difficult to insert the cds into the sgc was due to a tear in the silicone valve within the hemostasis valve.The tear was observed at the neck of the luer causing the manufacturing slit on the silicone valve to shift.As a result there is no straight pathway for the clip to enter the slit; therefore, making it difficult for the cds to be inserted.A definitive cause for how and when the tear occurred could not be determined.It is possible that the user technique contributed to the user experience; however, this could not be confirmed.Based on the information reviewed, there is no indication of a product quality issue with respect to design, manufacture or labeling of the device.
