So it looks like GenAccord may simple be a reboxing of an HMD Biomedical Inc. product line?
Looks like HMD had an FDA warning letter in 2017. They got a 510K approval in 2019 so I would assume that they probably got out from under this OK however.
K121433 or K113314 seem closest in intended use to DECNs Genaccord published information from what I can see. But there is a degree of speculation in there.
It seems unlikely that the FDA cleared 'GenAccord' was developed by DECN themselves though. Pharmatech website suggests it is a rebadged HMD Biomedical product
