It was reported that the procedure was to treat a mildly calcified, mildly tortuous lesion in the common femoral artery (cfa).An ht command 14 guide wire (gw) was advanced to the lesion without resistance, and a 4.0mmx80mmx150cm armada 14 balloon dilatation catheter (bdc) was advanced over the gw without resistance and inflated without issue.During an attempt to deflate the armada balloon, deflation was difficult, negative was held for approximately 30 seconds and the balloon only partially deflated after multiple attempts.An attempt was made to remove the bdc from the anatomy, however the bdc became stuck on the command gw and both devices had to be removed as a single unit.A new guide wire and balloon dilatation catheter were used to successfully complete the procedure.There were no reported adverse patient effects and no clinically significant delays in the procedure.

Visual inspection was performed on the returned device.The reported difficulty removing the device was confirmed.The reported deflation problem could not be replicated in a testing environment due to the condition of the returned device.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot that would have contributed to this event.Additionally, a review of the complaint history identified no other similar incidents and/or complaints from this lot.The investigation was unable to determine a conclusive cause for the reported deflation issue; however, the reported difficulty removing the device appears to be related to operational context.There is no indication of a product quality issue with respects to the design, manufacture, or labeling of the device.
