Visa for carer

[walker]

Scenario:
Disabled man requires carer.
However, for both personal and cultural reasons would like a relative from outside the UK and EEA to come to the UK and care for him.
What routes are available for the potential carer?

All help and guidance will be much appreciated.

Thanks

There is no 'carer' type visa.

What is this man's relationship to the relative outside the UK?
