Patent number: 9579416Abstract: This invention includes malleable, biodegradable, fibrous compositions for application to a tissue site in order to promote or facilitate new tissue growth. One aspect of this invention is a fibrous component that provides unique mechanical and physical properties. The invention may be created by providing a vessel containing a slurry, said slurry comprising a plurality of natural or synthetic polymer fibers and at least one suspension fluid, wherein the polymer fibers are substantially evenly dispersed and randomly oriented throughout the volume of the suspension fluid; applying a force, e.g., centrifugal, to said vessel containing said slurry, whereupon said force serves to cause said polymer fibers to migrate through the suspension fluid and amass at a furthest extent of the vessel, forming a polymer material, with said polymer material comprising polymer fibers of sufficient length and sufficiently viscous, interlaced, or interlocked to retard dissociation of said polymer fibers.Type: GrantFiled: January 20, 2014Date of Patent: February 28, 2017Assignee: KENSEY NASH BVF TECHNOLOGY LLCInventors: Timothy A. Ringeisen, William Christopher Wattengel

Patent number: 9017417Abstract: This invention includes a subchondral bone repair system, comprising a structural component and a fluid settable component and an optional non-core component. The fluid settable component may penetrate into any pores of the structural component, and set to a solid, thereby fixing the structural component in place. The fluid settable component will penetrate interporously into the pores of the subchondral bone tissue surrounding the device, beneficially displacing any fluid to reduce edema in the affected bone region. Furthermore, the settable component, once solid is osteoconductive to promote repair and regrowth of bone in the affected region, and will also transmit mechanical force stimuli (such as compressive forces) directed through the structural component, into the adjacent bone tissue, thereby providing appropriate force stimuli necessary for appropriate tissue growth.Type: GrantFiled: May 30, 2012Date of Patent: April 28, 2015Assignee: Kensey Nash BVF Technology LLCInventors: Gino Bradica, Timothy A. Ringeisen

Patent number: 8672941Abstract: Improved coring devices suitable for articular cartilage and bone, wherein the cutting device is capable of slicing through a tough protective tangential zone, delicately separating the shock absorbing columns of cells in the radial zone of the cartilage, and finally cutting into the hard underlying bone in a manner that preserves the viability of osteochondral cells. The coring device features an annulus having a flat annular cutting edge interrupted by at least one serration having neutral cutting angles. A method for concurrently removing cartilaginous and bony tissue using an improved coring device that preserves the viability of osteochondral cells.Type: GrantFiled: February 2, 2005Date of Patent: March 18, 2014Assignee: Kensey Nash BVF Technology LLCInventors: Gino Bradica, Timothy A.
