Manufacturer Narrative

Retained samples of the 4 different lot/batches of item t-601 [di portion: (b)(4)] (180222-0258, 180316-0259, 180326-0253, 180328-0254) and 10 different lot/batches of item w-601 [di portion: (b)(4)] (180221-0257, 180223-0259, 180305-0072, 180309-0255, 180330-0255, 180403-0256, 180416-0156, 180417-0157, 180425-0152, 180524-0075) have been inspected visually and electrically.Mechanical tests were performed on 4 retained samples of each lot number.All tested samples were found to perform within limits.No faults could be detected.The complaints were gathered by the sub-distributors over a period of 3 months and submitted to our distributor.Considering an earlier complaint originating from the same sub-distributor (reported as mdr 8020045-2018-00026) the annual number of cases can be estimated to be between 100 and 120.Leonhard lang manufactures and distributes (b)(4) electrodes of the models t-601 and w-601 per year (2018), (b)(4) of which have been distributed to the particular sub-distributor.This constitutes (b)(4) of the total.During the last twelve months no other complaints for skin irritation have been received regarding these two electrode models from sources other than the sub-distributor.We therefore assume that an additional parameter or circumstances yet unknown are causal for the increased incidence of skin irritations.The investigation is ongoing.We will provide a follow-up report once additional information has become available.

Event Description

On (b)(4) 2018, we have been informed about several incidents with ecg electrodes.Monitoring ecg electrodes (model sbw601 and sbt601) had been used with a verity ecg monitor.The initial report stated that "patients reported severe skin irritation with open sores and/or bleeding.There were 26 accounts from (b)(6) 2018 to (b)(6) 2019.(.) some patients discontinued use to awaiting healing or more information from physician and others were sent electrodes that are more sensitive, if possible, to try." the report referred to 26 separate cases, involving a total of 4 different lot/batches of item t-601 (50814) and 10 different lot/batches of item w-601 (50809).No further information was provided if and how the injuries had to been treated after the procedure.

Manufacturer Narrative

Retained samples of the 4 different lot/batches of item t-601 [di portion: (01)10861779000281 ] (180222-0258, 180316-0259, 180326-0253, 180328-0254) and 10 different lot/batches of item w-601 [di portion: (01)10861779000274] (180221-0257, 180223-0259, 180305-0072, 180309-0255, 180330-0255, 180403-0256, 180416-0156, 180417-0157, 180425-0152, 180524-0075) have been inspected visually and electrically.Mechanical tests were performed on 4 retained samples of each lot number.All tested samples were found to perform within limits.No faults could be detected.The complaints were gathered by the sub-distributors over a period of 3 months and submitted to our distributor.Considering an earlier complaint originating from the same sub-distributor (reported as mdr 8020045-2018-00026) the annual number of cases can be estimated to be between 100 and 120.Leonhard lang manufactures and distributes 21.4 million electrodes of the models t-601 and w-601 per year (2018), 3.5 million of which have been distributed to the particular sub-distributor.This constitutes 16,5 % of the total.During the last twelve months no other complaints for skin irritation have been received regarding these two electrode models from sources other than the sub-distributor.We therefore assume that an additional parameter or circumstances yet unknown are causal for the increased incidence of skin irritations.No information on skin type, state of skin, whether any medication was being taken, which might have a skin weakening effect, and how the skin was prepared before application of the electrodes was provided.We have requested further information on each of the events.We also have requested why these complaints have been collected without providing any information to us and whether there were any recorded skin reactions before.We have repeatedly requested for further information and were not able to obtain any.We have tried to get a direct contact to the company preventivce but our distributor disclosed:" please note that fh medical requests lang gmbh not contact preventice solutions directly, if you have questions please let me know and i will communicate accordingly".So we received a signed preventice letter on (b)(6) 2019 were in it is stated: "per the preventice complaint records, ass pertinent information has been provided to leonhard lang regarding the model electrodes that preventice purchases through fh medical that are manufactured by leonhard lang.We have provided all information that we have on these instances at this time; however, if more information becomes available that information will be provided at that time." on (b)(6), we received the information that "there are no other updates to provide for the previous complaints".As no further information was available despite repeated requests for the already existing incidents we have designed a new questionnaire taylored to the customer's special use model.With the new questionaire, we are confident to receive improved information on future incidents to be able to determine a root cause.However as no further information was made availbe on the incidents covered in this report, no conclusion can be drawn what might have caused the customers problems.We consider the investigation closed and will only resume it when new cases are reported.We would cover them under a new mdr.
