Pma/510(k) #k142688.Device evaluation: the echo-hd-3-20-c device of lot number c1610470 involved in this complaint was returned for evaluation, with the original packaging.The packaging was open on receipt.With the information provided, a physical examination and document based investigation was conducted.Lab evaluation: the device related to this occurrence underwent a laboratory evaluation on the 04dec2019.Refer to attachments (b)(4)_lab attendance and (b)(4)_lab evaluation notes for lab attendance and notes.The returned device lab examination findings and observations can be referred through attached photos (ref att.'(b)(4)_lab decon evaluation photos').There was three failure modes observed.The needle tip was returned separately.The three failure modes are as follows: a distal kink at the notch area.A break at the distal end of the needle.A kink approximately 1.2cm from tip of sheath.It is likely that the initial failure mode was the distal kink and thus the needle tip broke and sheath kinked.All failures observed are linked.Document review: prior to distribution, all echo-hd-3-20-c devices are subjected to functional checks and visual inspection to ensure device integrity.These inspections and functional checks are outlined in internal procedures in place at cirl.A review of the relevant manufacturing records (c1610470) revealed no discrepancies that could have contributed to this complaint.Upon review of complaints, this failure mode has not occurred previously with this lot number.Based on the information available to date, there is no evidence to suggest that there are any manufacturing issues associated with lot number c1610470.There is no evidence to suggest that the customer did not follow the instructions for use (ifu0077-4).Root cause review: a definitive root cause could not be determined as the circumstances of use cannot be replicated in the laboratory.A possible cause could be attributed to the distal part of the needle coming into contact with a hard part of the patient anatomy leading to a distal kink and possibly in turn led to the needle breaking when outside the patient.Summary: complaint is confirmed as the failure was verified in the laboratory.According to the initial reporter, the patient did not experience any adverse effects due to this occurrence.Complaints of this nature will continue to be monitored for potential emerging trends.
