Event Description
|
The healthcare professional reported that during a primary balloon sinuplasty procedure targeting the sphenoid sinus, the trudi suction device (tdns000z / s/n: (b)(4) / lot# unk) was not in its accurate location; it was off by more than 2mm.There was no issue noted during the set up and registration of the suction tool.The device was initially accurate and then later appeared to be inaccurate.This issue was not noticed in previous uses of the device.When the loss of accuracy was observed, the icon on the trudi system was green.The physician was able to connect to a new suction device.The procedure was completed without any patient injury.It was reported that the suction device has been reprocessed less than 5 times.

Manufacturer¿s ref.No: (b)(4).The purpose of this mdr submission is to report the investigational finding of the returned device.[conclusion]: the healthcare professional reported that during a primary balloon sinuplasty procedure targeting the sphenoid sinus, the trudi suction device (tdns000z / s/n: 1901080049 / lot# unk) was not in its accurate location; it was off by more than 2mm.There was no issue noted during the set up and registration of the suction tool.The device was initially accurate and then later appeared to be inaccurate.This issue was not noticed in previous uses of the device.When the loss of accuracy was observed, the icon on the trudi system was green.The physician was able to connect to a new suction device.The procedure was completed without any patient injury.It was reported that the suction device has been reprocessed less than 5 times.The product was returned for evaluation.The investigational finding is documented below.Investigation summary: the trudi suction device was received.Before undergoing decontamination, visual inspection was performed.There was no appearance of damage observed.The returned device underwent decontamination with a 10% bleach solution for two hours.After decontamination, the following electrical tests were performed and completed using the lab multimeter (id#: us2172.Calibrated on 02-15-2019 / due on 02-29-2020): 1) sensor connectivity: 0l mo (specification: 188 o ± 25 o).2) shield connectivity to stainless steel body: 1.4o (specification is < 10 o).3) the eeprom connectivity: 439.5 ko (specification is > 50 ko and < 10mo).4) isolation between sensor and shield: 0l mo (specification is > 1 mo).5) isolation between sensor and eeprom input/output (i/o): 0l mo (specification is > 1 mo).6) isolation between sensor and eeprom ground (gnd): 0l mo (specification is > 1 mo).7) isolation between shield and eeprom input/output (i/o): 0l mo (specification is > 1 mo).8) isolation between shield and eeprom ground (gnd): 0l mo (specification is > 1 mo).Note: 0l mo indicates the reading exceeds the maximum indicated value of the multimeter.Upon completion of the electrical test, it was identified that the sensor connectivity test resulted in an out of specification result reading of 0l mo (specification: 188 o ± 25 o).The reported issue that the trudi suction device was not in its accurate location was confirmed based on the evaluation and functional analysis performed on the returned device.It was identified that the sensor connectivity was out of specification (specification: 188 o ± 25 o); the multimeter reading was 0l mo.The device lot number was not available.The device history record (dhr) review could not be performed without the lot number.As part of the post market surveillance program, information from this complaint is trended for statistical signals and corrective/preventive action may be triggered at a later time.Since there was no evidence to suggest the event was related to a manufacturing or design issue, no corrective actions will be taken at this time.Updated sections: g.4, g.7, h.2, h.3, h.6, and h.10.This is one of 2 products involved with the reported complaint.The associated manufacturer report numbers are: 3005172759-2019-00121 and 3005172759-2019-00122.The manufacturer will submit a supplemental report if new facts arise which materially alter information submitted in a previous mdr report.Additional information will be submitted within 30 days of receipt.
