Hey, 

On basis of demand in market i will suggest you to go for biomedical and if you also have good skill set like basics of medical equipments and elctronics.It is very easy to get into a MNC .

Biomedical engineering deals with the instruments required for medical industry. It is an amalgamation of electronics and biology so the subjects will be inclined to electronics.

whereas,

On the other hand Hospitals now a days are having one or more biomedical engineers because of NABH and quality requirement.

hope it helps
