Investigation summary: a device history review was conducted for lot number 7327621.Our records show that this is the only instance of this issue occurring in this production batch.According to the sampling plan applied for product performance, this lot was accepted and released without defects being noted during the final assembly or visual inspections.Additionally our quality engineers have reviewed the samples submitted, and during leakage testing they determined that the only leaks present in the device were found at the puncture points in the catheter tubing.In response to the damaged catheter our engineers conducted a review of the manufacturing process but were unable to identify any opportunities to generate this failure mode in our manufacturing process.The root cause for this complaint could not be determined at the conclusion of our review.The reported leakage and needle through catheter were confirmed in both samples after to be inspecting.Based on investigation results to date, the root cause cannot be determined; however, by the conditions of the defect a possible cause could be the incorrect use from product.
