How do you find help / financial backing for an invention by a 93 yr old without finances?
I am unsure where you should look for financinng or assistance, but please make sure that you and your friend don't get taken by some scumbag who tells you he's trying to help, then steals the idea.  I have heard that, that type of thing happens alot with people and patent companies and the like.  Just be careful who you trust, ESPECIALLY if you find them on the internet.\n\nMaybe you should look into the TV Program "American Inventor" website if they have one?  Just a thought though. Sorry I couldn't better assist you.\n\nGood Luck.
Two things come to mind here.  First, specific schools often have "local" scholarships which are available to specific categories of students.  Sometimes these relate to field of study; sometimes they relate to some aspect of the student--ethnicity, sex, birthplace/hometown; sometimes they are based on need.\n\nThe second possibility, if you are in the U.S., is with the Bureau of Health Professions (of the Health Resources and Services Administration, within the Department of Health and Human Services).  At the link below, you will find that they sponsor grant programs, as well as loan repayment programs.
