Manufacturer Narrative

A 106cm/18 cm ekosonic catheter (sn: (b)(4)) was used to treat a patient with peripheral arterial occlusion on (b)(6)2017.After successfully placing the infusion catheter (iddc, part of the ekosonic device) in the patient, the treating physician attempted to place the ultrasound core wire (microsonic device, msd) where it failed to track through the iddc.The physician successfully placed a new ekosonic catheter device.This was reported to ekos on (b)(6)2017 and investigated through our complaint system under cer (b)(4).The catheter was returned to ekos for investigation.Our evaluation found the iddc was damaged.Both distal and proximal marker bands on the iddc are displaced about 1 to 2mm from the original location, and both marker bands are flattened and not round anymore.The device history record shows the iddc passed guide wire test, marker band inspection, as well all other tests before shipped to the customer.Our evaluation of the returned device also showed pinch marks on the msd and the msd failed to advance in the iddc due to misshaped the marker band and tubing.We advised the customer on correct handling of the ekos devices.The instructions for use contain the following warning "warning: if an iddc or msd becomes kinked or otherwise damaged during use, discontinue use and replace." we are filling this mdr in response to the user facility's medwatch report #(b)(4) that we received from the (b)(4) on 8/28/2017.It was reported in our complaint investigation follow-up that the patient was "good".The follow-up on (b)(6)2017 stated the patient completed therapy and it was reported "the clot totally lysed, great pedal pulses, and ekos catheter was [discontinued]" with a total therapy time of approximately 16 hours and that the "patient is doing remarkably well.".
