Brothers Med and Funeral Expenses

My brother Isaac is a 49 year old husband, father of 2 and grandparent on two young boys. Isaac, on July 26th, went in for a surgery to remove a growth from his pancreas. After 2 hours of surgery they said everything went great and he was to stay in the hospital for a few days. On July 27th my sister in-law stay with him all day after leaving the hospital  texted each other good night at 9pm. July 28th she received a call stating my brother was found unresponsive. He was resuscitated after 40 mins but never regained consciousness. Today July 30th he was pronounced brain dead and was taken off of life support and passed shortly thereafter.  My brother was the sole support for his wife and as you can imagine there are now medical and funeral expenses that need to be paid not to mention expense while she gets on her feet and deals with the loss of her husband of over 20 years.  Every little bit helps and would be greatly appreciated. Thank you in advance.
