Sorin group (b)(4) manufactures the dideco ats autotransfusion cardiotomy reservoir.The incident occurred in (b)(6).This medwatch is being filed on behalf of sorin group (b)(4).Sorin group (b)(4) received a report that the filter became detached from the autotransfusion cardiotomy reservoir during a procedure.There was no report of pt injury.The unit was discarded by the hospital and therefore, no eval could be performed to confirm the report.However, based on previous cases with a similar description, it was determined that a blow to the reservoir lid could cause the connector, which joins the filter to the reservoir lid, to crack and lead to a filter detachment.It is likely the reported issue was caused by a crack in the connector due to a mechanical force.Sorin group has implemented corrective and preventative actions to strengthen this specific area of the reservoir.The coupling system between the reservoir top lid and the upper part of the internal filter has been strengthened.Additionally, a rib was added to the vacuum port to add add'l strength to this portion of the reservoir.The reservoir was manufactured after these corrective actions were implemented.These corrective actions have reduced the number of these complaints although these types of complaints will continue to be monitored.
