Daniel Kraft from the Stanford Institute for Stem Cell Biology and Regenerative Medicine invented a device to make bone marrow harvesting in donors a less invasive and less stressful process on the body. The idea is to drill one hole into the pelvis and then to approach the bone marrow from different angles, thus widening the harvesting region.
Here’s a TED talk of Kraft presenting the MarrowMiner device:
