Manufacturer Narrative

Micromatrix was not returned for evaluation (resorbable product).Additional information received from the customer, indicated the device (a powder) was hydrated or reconstituted with prp and adipose fat (stem cell) for the doctor to be able to inject the reconstituted product inside the nasal cavity of the patient.The micromatrix is not intended for use in empty nose symptom and should not be reconstituted with prp and adipose fat (stem cell).As product reference no, lot number and serial number are not available, a comprehensive review of manufacturing records (dhr) was not possible.However, every micromatrix lot is manufactured following stringent validated processes under class 7 clean room conditions and is sterilized to sal10-6 using electron beam irradiation sterilization process.Furthermore, all lots of micro matrix devices are also tested for endotoxin three times, immediately following disinfection, in-process and final device lot release testing (after sterilization).Integra/ acell endotoxin specification is established as per usp <161>.Any lot not meeting the endotoxin specification the entire lot is immediately rejected and scrapped.Root cause is undetermined.With the information provided by the complainant thus far, a definitive source or cause of infection cannot be established.Micromatrix is not recommended to be reconstituted with prp and adipose fat (stem cell), and also is not recommended to be used for empty nose symptom which is deemed a modification to the product and an off-label use.It is also unknown if the doctor shared the content of one vial of micromatrix with more than one patient.As per ifu, the device is intended for one-time use.In addition, it is also unknown how the device (a powder) was hydrated or reconstituted with prp and adipose fat (stem cell) for the doctor to be able to inject the reconstituted micromatrix inside the nasal cavity of the patient.Unknown if the reconstitution process was aseptic.
