Broken branch prunus cheals weeping

Do you have any pics of the damage and tree to give members an idea of the situation. I have a Acer Brilliantissismum that I need to prune some of the lower branches off but I won't do that until the sap has stopped moving until November to stop bleeding. If it's the leading branch that has been broken, i.e. the one that would have given it more height, what normally happens is that the tree will throw out more branches and you could use one of those to gain more height and balance. But as you are saying that the branch is splintered and not completely broken off there was a thread on GC not very long ago about a member strapping a branch'trunk up so that it would bind back together, you could try that.
