As a Patent attorney that has done many a medical device I would estimate that it would be $1200 to $1500 to have a good quality provisional submitted on your behalf. Note some firms will charge $500 to get a provisional patent application filed but it is worthless down the road and can get you in more trouble that you can imagine if you are suing someone later for patent infringement. I suggest a different approach that is more cost effective overall and gives you an excellent starting position. If you wish you can call me and I can explain the process fuller.
