ADuM6201 EMC testing failed, noise, BT communication jammed

Our new devices failed at EMC testing because the ADuM6201 isolation IC produced above the max. level noise and jammed the BT communication. The other problem was the IC's high temperature during operation. The device is a medical one and we have to lower the level of the noise and temperature.

What would be your advice, or could you offer a similar product that would be a better solution (size is of importance only smaller once are applicable)?

Thanks for your answer
