Hugo: You may be correct, I drove by on El Camino Real - North, leaving Doubletree, and glanced into the business park. The "Cardium" sign at ECR is still there, but there is no sign on the building where the "headquarters" were (supposed to be). I don't think there are any employees left... and no $$ even for the rent.
Bankruptcy has probably been filed and just not disclosed. No $$ for a press release either.
