Transplants and Transfusions

Q: I currently live in Bangladesh. My father suffers from liver cirrhosis. I have plans to do Masters or PhD in USA. It is recommended for my father to do liver transplant but currently the liver transplant is not available in Bangladesh and in India it will cost 1-1.5 crore Bangladeshi Taka(currency), which is out of my reach.

When I start PhD in US, will it me permissible for me to buy an insurance for my father, take him to US and do the liver transplant and then send him back to Bangladesh? I cannot find any Takaful Health Insurance in US and don't know how the rest of the insurance work there.
