Additional Manufacturer Narrative
(b)(4).The manufacturing dhr file was reviewed.It was revealed that during one test "test - fct" the result was "automatic fail".However, 3 additional attempts were completed , and the result was "pass" in each successive attempt.Therefore, the unit must have met all requirements for release.Ez-io driver 9058 (sn (b)(6)) was returned for evaluation.Upon receipt, the driver was visually inspected.There were small black marks observed on the driver which is the result of normal use.When the trigger was pulled, the driver was operable , and a solid green led light was displaying.The led was not flashing green as reported.The driver was then subjected to simulated sawbone insertions per driver ifu.This functional test is used to determine whether the returned device still has the capability to power a 45mm ez-io needle set into a medium and/or hard bone.The 45mm ez-io needle set is used because it represents the worst-case scenario for io insertion.Two (2) sawbones with medium (50 lbs/ft 3) and hard (105 lbs/ft 3) hardness profiles with 3mm cortexes were used for the test.Each insertion was timed with a stopwatch (id: ref-003150) while applying approximately 8 lbs.Of force on a weight scale (id: ref-002481).Approximately 5 to 8 lbs.Of force is necessary to penetrate bone.Below are the test results: the driver successfully negotiated both the medium and hard saw bone insertion testing.The complaint cannot be confirmed.The driver was opened to test and record operating characteristics.Battery voltage measured as 17.64 dc volts (voltmeter: ref-002629) without being activated.Battery voltage measured as 14.91 dc volts when button was activated , and voltage reached a stable level.Stable defined as when whole numbers (e.G., 6 volts, 7 volts, etc.) stop changing (ignoring numbers after the decimal point).The measured voltage is slightly lower than the nominal specification of 18.2v for the battery pack upon release.This is expected after device use.The eeprom was parsed , and the results reveal the charge count was 5,063,518 and the cycle count was 636.The cycle count of 636 (trigger activations) is significant as it substantiates driver usage with considerations to bone density, average insertion time, storage, and frequency of testing.The eeprom results confirm that the battery is not depleted as the charge count has not exceeded the maximum depletion value of 15,300.Additionally, 4 stall conditions were recorded.The stall conditions may be the result of excess downward pressure on the driver during use.Testing confirms that there was no fault found with the returned driver.Two ifus will be referenced for this investigation.The ez-io driver ifu (8048a rev.04) states, "as with any emergency medical device carrying a backup is strongly advised protocol", "ez-io power driver led will blink red when the trigger is activated and has only 10% of battery life remaining".The ez-io needle ifu states, "squeeze trigger and apply gentle, steady pressure.Important: do not use excessive force.Note: if ez-io power driver stalls and ez-io needle set will not penetrate the bone, operator may be applying too much downward pressure to penetrate bone." a review of the device history record found that the driver passed all the release criteria.The device was released in 11/2017 and is approximately 5 years old.In summary, the complaint cannot be confirmed.Functional testing revealed no fault found with this driver as the device was able to negotiate both the medium and hard saw bones during insertion testing.No defects or anomalies were observed with the returned driver.A device history record review was performed , and no recorded results of manufacturing issues or anomalies were reported.Teleflex will continue to monitor and trend on complaints of this nature.
