Patent number: 8852119Abstract: A bone marrow harvesting device includes a flexible bone marrow harvesting needle that can bend during operation to prevent the needle tip from piercing the inner cortical wall of the target bone. The needle defines an aspiration channel that defines an intake end that is recessed to reduce the instances that the aspiration channel will be fouled by bone particles or other debris within the cancellous portion.Type: GrantFiled: October 5, 2011Date of Patent: October 7, 2014Assignee: DePuy Synthes Products, LLCInventors: Kortney Wawrzyniak, Peter Kurzyna, Michael Lehmicke, Sean Kerr, John Maurice Marthaler, Steven Paul Parmelee

Patent number: 8057595Abstract: The present invention relates in general to implantable compositions, and method for preparing same, containing a calcium salt-containing component, optionally demineralized bone, a plurality of discrete fibers, optionally a flow additive, and optionally continuous reinforcing fibers or an array of organized fibers in the form of mesh. Advantageously, the discrete fibers have a specific aspect ratio (length/diameter) from about 50:1 to about 1000:1. The addition of a small amount of discrete fibers and/or the continuous reinforcing fibers or fiber mesh can cause drastic increases in certain mechanical properties including flexural strength, flexural toughness, and/or screw pullout strength.Type: GrantFiled: November 3, 2009Date of Patent: November 15, 2011Assignee: Synthes USA, LLCInventors: Bryan Monro Armitage, Ira Ison, Mark Fulmer, Sean Kerr, Michael Lehmicke, Patrick Leamy, William Schiffer
