Bone marrow aspiration system

Patent Number: 6981948

As mentioned in our discussion about patent # 7008394, bone marrow harvesting is a relatively invasive procedure. This is also very relavant for regenerative uses of bone marrow where patients with a heart attack or stroke are harvested. Accordingly there is a need to develop less invasive and increasingly sterile means of harvesting. The current patent has two independent claims covering a novel bone marrow harvesting device. The first independent claim covers "a bone marrow aspiration device" whereas the second covers "A method for preparing an implantable substrate". Both are directed towards what appears to be a closed system device of extracted bone marrow cells.
