20160135961 | DEVICE TO BE IMPLANTED IN HUMAN OR ANIMAL TISSUE AND METHOD FOR IMPLANTING AND ASSEMBLING THE DEVICE - An implant or endoprosthesis suitable to be implanted in human or animal tissue includes two (or more than two) parts to be joined in situ. Each one of the parts includes a joining location, the two joining locations facing each other when the device parts are positioned for being joined together, wherein one of the joining locations includes a material which is liquefiable by mechanical vibration and the other one of the joining locations includes a material which is not liquefiable by mechanical vibration and a structure (e.g. undercut cavities or protrusions) suitable for forming a positive fit connection with the liquefiable material. The joining process is effected by pressing the two device parts against each other and by applying ultrasonic vibration to one of the device parts when the two parts are positioned relative to each other such that the two joining locations are in contact with each other. | 05-19-2016 |

20160374820 | ENGINEERED INTERVERTEBRAL DISC (IVD) FOR DEGENERATED DISC DISEASE - The present invention provides a process by which both non-tissue engineered and tissue engineered cartilaginous-like structures can be fabricated. The process of the present invention provides a method to produce electrospun nanofiber-anchored NP gels. The present invention provides a functional design for novel engineered IVD. The present invention provides a method for fabrication of both non-tissue and tissue engineered IVDs. These cartilaginous-like structures can be used to produce replacements for degenerated natural IVD. The method of the present invention uses electrospun PCL nanofiber mesh to anchor the NP. The method of the present invention can create angle-ply AF structure around the circumference of NP to mimic the architecture of native IVD. The method of the present invention anchors the top and bottom sides of NP by using non-woven aligned or random nanofiber mesh to create scaffold for the generation of endplate (EP) tissue. | 12-29-2016 |

20220133502 | GRAFT DELIVERY SYSTEM - A system for delivering bone graft material into an interbody fusion device (IBFD) in an intradiscal space of a spine, the IBFD having an open-frame with a hollow interior and an opening through its proximal end communicating with the interior. Included is an elongate channel having a lumen extending therethrough, the distal end being in engagement with the IBFD to align the lumen with the opening through the proximal end of the IBFD. An adjustable block is movably attached to the channel, the block having plural chambers containing bone graft material, the chambers being individually sequentially alignable with the lumen. A plunger pushes graft material from each chamber, through the lumen and into the IBFD. A distal end of a tamper is configured to be inserted through each chamber and the lumen and into the IBFD interior for tamping graft material deposited into the interior of the IBFD. | 05-05-2022 |
