Can you get travel insurance if you have a internal defibulator?

My dad lives in New Zealand and is traveling to the USA and does not seem to be able to fined travel insurance. He has a internal defibulator and has been told by several travel insurance company's that they won't give him travel insurance. Does anyone know who may give it to him?Can you get travel insurance if you have a internal defibulator?You will have to contact as many insurance companies as you can find to see if any offer it. I don't think you'll find any answers here for such a specific problem. Make sure that if you do find one that the exclusions don't make it worthless.
