Event Description

The customer initially provided cmi (manufacturer) with the following problem description on 07/11/2018: at the end of the procedure when the dr was withdrawing the sheath, there was resistance and the patient was complaining of 10/10 pain.As he continued to withdraw the sheath it appeared to "unravel".Pt required further analgesia and imaging to ensure that no remnants were left in the patient.On 07/18/2018, the customer provided cmi with additional information: i had a further conversation with the dr yesterday.The patients groin was very scarred and had a venous bypass graft.It tracked ok on introduction to the artery via the bypass.It was on withdrawal that the resistance was encountered.They noticed that the sheath was withdrawing (or appeared to be) but on imaging the distal opaque marker was not moving.This is when he realised that the sheath was uncoiling or "stretching" due to the resistance.He did reintroduce the dilator, however the sheath had stretched so the dilator did not reach the distal tip.It did help to withdraw the sheath further.He did require to use artery forceps to get enough traction or "grip " on the sheath to withdraw fully and this is when the sheath split into 2.He is confident that there was no parts of the sheath left in the patient.The additional information caused re-assessment of the reportability of this event.Note: the dilator was not used since the beginning of withdrawal, it was re-inserted at the time when the doctor felt the resistance.

Manufacturer Narrative

Sample evaluation: after the return of the sample, prior to the investigation the sample was sent to the external laboratory for decontamination the returned sheath was inspected and physical damage was confirmed.The outer sheath broke which exposed the inner metal reinforcement.The tip section itself showed no sign of damages.Complaint investigation information: the customer provided cmi with information, that the dilator was not in place while the retraction of the sheath began.This is a violation of instruction in ifu, section precautions.Another violation of ifu, section warnings, was that the end user continued with withdrawing of the introducer despite the resistance without determining the cause.The factors possibly contributing to the incident: as was reported by the customer the patient has calcified lesion and the lesion length was 150mm - it is possible that the sheath got stuck in the calcified lesion; the vessel vasoconstricted (due to a vessel spasm) and therefore the introducer sheath was hard to remove from the patient.Root cause: the root cause of the incident is most likely end user error - did not follow the instruction in ifu, together with the patient conditions/anatomy attachment: (b)(4).
