I made my own removal tool to draw out the wedge from the opposite side. Get a thin piece of flat steel bar (approximately 1/2in wide, 4 inches long). Get a shorter 4mm bolt.
Remove the crank arm on the opposite side you pulled the bolt out of so you can access the wedge. Put the steel piece across the bottom bracket shell over the wedge bolt hole. Thread in the bolt through the piece of steel (you may need to add some washers to take up some length). Then tighten the bolt against the steel piece to draw out the wedge.
I hope that makes sense.
