Evaluation summary: post marketing vigilance (pmv) received two devices, opened by the account with the appropriate display box and blister packaging in an undamaged condition.This evaluation was based on a technical review of all data received from the site, a pmv review of manufacturing records, a pmv review of complaint trends, and an evaluation of the returned device.Instrument 1 was observed to have a bent needle in the jaw.Witness marks were observed on the cones of the needle.No witness marks were observed on the bevel wall of the instrument.No sheering on the toggle switches was observed.The needle was unloaded from the jaws of instrument 1.Both instruments were loaded with a needle from the post marketing vigilance (pmv) inventory and applied to test media.Pressure was exerted on the needle in all directions from both sides of the jaws during this test in an effort to simulate clinical conditions.The instrument was found to function properly and each needle remained intact.No difficulty was experienced in loading, unloading, or toggling the needle for both instruments.A review of the device history record indicates this device lot number was released meeting all quality release specifications at the time of manufacture.Replication of the bent needle may occur when the needle is not loaded properly or when the needle is forced into an obstacle.This condition may also occur if excess pressure is exerted on the needle or the attached suture while the jaws are in the open position.In these situations, the needle may flex and ultimately break.The returned sample will be retained according to medtronic standards.Should new information become available, the file will be re-opened and the investigation summary will be amended as appropriate.
