If a device is designed to work with other medical devices as a complex,
1. Software developed for a specific medical device. These applications are tested together with the device as part of the registration process.
2. Standalone applications. These are tested independently. They are less expensive to register than a medical device, since they are not subject to toxicological trials. Time wise, however, they may take similar 4-5 months, as there are only a couple of government laboratories authorized to perform such testing.
Risk Class of software for medical devices is the same as of the medical device it is used with.
