The customer reported that during use of the spectrum autopass suture passer needle with a spectrum autopass suture passer in a shoulder arthroscopy rotator cuff repair procedure, the surgeon had difficulty passing the suture through the tissue on the fourth pass.During which time, the surgeon noticed that the tip of the nitinol spectrum autopass needle had broken off and was missing.The surgeon physically searched for the tiny broken tip in the surgical site, but was unable to locate it.The surgeon then used the suction of a shaver blade (typically used in this type of procedure) in attempt to remove the broken tip.A second needle was used and the procedure was completed with no further complications or patient injury.To date, there has been no additional information received regarding the patient's latest condition or any indication that a long term adverse effect has occurred.
