Redax was not able to perform a complete investigation since the lot number nor the sample were available.We have tried to require to our (b)(4) distributor the lots sold to the hospital but they were not able to identify them as the sale is not performed directly to the hospital but to (b)(6) supply chain.For these reasons, the analysis has been done just on the basis of the information provided by the hospital.The chronology-timeline events described are quite confused, even if well detailed.It appears that the drain was handled not correctly and several times as it was positioned in the right side then they found it in the abdo.It appears from the description that the drain went completely inside the patient and it was tugged and moved in order to re-position it.All these operations could have weakened or damaged the drain, causing consequently the rupture.No similar cases have been registered from last year till today.The raw material has not been changed and it is in compliance with the tests required by international standard iso 10993-1.No actions will be done for the moment, just take under control the situation and the market.
