As reported, the spectrum autopass needle is expected to be returned for evaluation.However, as of this filing, the "used/damaged" needle has not yet been returned from the user facility.A supplemental and final report will be filed upon the completion of the device evaluation and the complaint investigation.

The user facility reported that during use of the spectrum autopass needle with a spectrum autopass suture passer in a shoulder arthroscopy procedure on (b)(6) 2017, the tip of the needle broke off in the surgical site.As reported, the breakage occurred during the fifth or sixth pass of the needle through the tendon.Attempt to retrieve the tiny broken fragment failed, as the fragment could not be located or retrieved.Other than a delay of approximately 15-20 minutes, the procedure was otherwise completed with no further complications or serious injury to the patient.This report is filed on the basic of potential for patient injury with recurrence.

One (1) used spectrum autopass needle was returned to conmed for evaluation on 11-may-2017.Visual examination found the tip of the needle was broken off and the tiny broken tip approximately 1.52mm was not returned.Further examination of the needle found evidence of misuse due to needle bending.Based on the evaluation finding, it is believed that the most probable cause of the reported needle tip breakage was use related.This lot #33954 was manufactured on 24-nov-2015.Of the lot containing 2,020 units, there have been 2 other similar complaints received for this item and lot number combination.A 2-year review of complaint history shows there have been a total of 44 reports of tip breakage with a quantity of 45 units, including this one.During this same time frame, approximately (b)(4) units have been sold worldwide, making the rate of occurrence for this failure mode 0.(b)(4).To date, there have been no patient long term adverse effects resulting from this type of incidents.The use of the autopass suture passer and needle is very technique dependent.This failure mode is addressed in the dfmea and the risk analysis has been deemed acceptable.The needle shaft and blade are made of 96se508 super elastic nitinol.A material routinely used in the manufacture of medical instruments with a long history of safe and effective clinical use.Nitinol is used in vascular stents, valve patches and orthodontic devices.To reduce the risk of needle breakage and patient injury, the information for use (ifu) provides the user with the following warnings: avoid lateral stresses to the instrument or device function may be compromised.Do not use if parts are broken, cracked or worn, or device function may be compromised.Whether used arthroscopically or in open surgery the suture passer must be used under direct visualization.If tissue is excessively thick or rolled and suture passer jaws do not close far enough there is a chance of suture passer needle missing the window of the suture retrieval mechanism.If the suture passer needle kinks during use, immediately discontinue use and discard.There is an increased risk of needle breakage and unintentional patient injury may result.Do not use disposable suture passer needle for more than one (1) procedure.Reuse could cause fatigue and/ or breakage of the needle, which may cause possible patient injury.
