OMG! We totally solved the problem with gun shot wounds!!!!!!!1!!!1!! Ones left there on purpose. The problem with this entire concept is that people who are victims of gun shot wounds rarely die from external bleeding. This "gun shot patch" will not work for internal bleeding in large body cavities. It will not stop solid organs from bleeding into potential spaces. It will not stop an injured lung from leaking air or blood and causing a pneumothorax or hemothorax. Gun shot wounds are incredibly complex. This "plug" will only be useful in a minority of wounds caused by gunshots and probably cost ridiculous amounts of money to produce...not to mention the problems of having to pull out dozens of small sponges to actually evaluate and repair a wound on the physician side.
