Manufacturer Narrative

The customer reported that the needle was separated from the microtip.Needle separation was confirmed upon receipt of the handpiece.The needle tip was returned alongside the microtip.Due to the state in which the device was received functional testing could not be performed.The hypodermic needle had separated at the braze joint.This is the highest stress point along the length of the needle.There was no indication of severe side loading or contact with hard tissue.The immediate cause is material fatigue associated with and/or being caused by user error.It is suspected that non-axial motion by the user is the primary contributing factor to the needle breaking.Lab testing, to date, has been unable to duplicate needle failure when appropriate axial technique is used in simulated use conditions.

Event Description

Per the information provided, during a plantar fasciotomy the needle separated from the microtip at 1:10 minutes.The doctor noticed a change in the acoustic sound of the device and removed the microtip from the patient.He then noticed that the needle was loose in the sheath.Another microtip was used to complete the procedure.There was no harm, injury or complication to the patient caused by the failure.
