20130196369 | Methods of Culturing Retinal Pigmented Epithelium Cells, Including Xeno-Free Production, RPE Enrichment, and Cryopreservation - The production of high quality retinal pigmented epithelium (RPE) cells is necessary for research and potential therapeutic uses. Especially desirable are methods for the production of RPE cells using xeno-free culture conditions. Disclosed herein are novel methods for the production of RPE cells from pluripotent cells with high yields, including xeno-free production methods. Also provided are methods of efficiently isolating RPE cells from cultures containing heterogeneous cell types, allowing for substantially pure RPE cell cultures to be established. Additionally, novel methods for the cryopreservation of RPE cells are provided. | 08-01-2013 |

20080288073 | Self-Distracting Cage - Various spinal implants and methods for stabilizing the spine are provided. In one exemplary embodiment, a spinal implant is provided having an expandable container with an interior volume that is selectively expandable between a compressed condition and an expanded condition. The expandable container is coupled to a superior endplate member having a bone-contacting surface and an engagement surface effective to mate with a superior surface of the expandable container, and an inferior endplate member having a bone-contacting surface and an engagement surface effective to mate with an inferior surface of the expandable container. In addition, at least one inlet port is formed in the expandable container and is effective to communicate a fluid to at least one cavity disposed within the interior volume of the expandable container. | 11-20-2008 |

20110066192 | Expandable Ring Intervertebral Fusion Device - An expandable tube having a substantially semicircular unexpanded shape is inserted into the disc space after the disc material has been removed therefrom. A plurality of expandable lockable rings are passed over this tube in their unexpanded states and positioned along the anterior edge of the endplates. The tube is then expanded, thereby forcing the rings to expand. The rings hold their final expanded configuration via a one-way locking mechanism. Once sufficient distraction is achieved and the rings locked, the tube is collapsed and removed, thereby leaving the expanded, locked rings behind to support the disc space. | 03-17-2011 |
20130030471 | CROSSOVER SPINOUS PROCESS IMPLANT - A device intended for the treatment of spinal stenosis. This device is an inter-spinous spacer that is introduced through a single posterior incision. It uses a single piece insertion technique with a unilateral approach. The surgeon does not need to access the opposite side of the spinous process. It allows the user infinite adjustability in distraction height with a single locking mechanism. | 01-31-2013 |

20120078308 | ROD REDUCTION INSTRUMENT AND METHODS OF ROD REDUCTION - An instrument for reducing a spinal rod includes a reduction member sized and shaped to be positioned about an anchor extension connected to a bone anchor, an actuator assembly connected to the reduction member and operable to move the reduction member distally relative to the anchor extension along a longitudinal axis of the anchor extension, and a connection mechanism for removable and replaceable connection of the actuator assembly to a proximal end of the anchor extension. The connection mechanism is adjustable between a first position in which the connection mechanism connects the actuator assembly to the proximal end of the anchor extension and a second position in which the connection mechanism and the actuator assembly are released from the anchor extension. | 03-29-2012 |

20150088148 | MEDICAL IMPLANT DRIVER WITH DEPTH-LIMITING FEATURE - Devices, systems, and methods for driving an implant into bone to a predetermined depth are described herein. In one embodiment, a medical driver tool is provided that includes a housing having a proximal end configured to receive an impacting force, an elongate shaft extending distally from the housing and having a distal tip configured to drive an implant into bone, and a release mechanism coupled between the housing and the elongate shaft. The release mechanism can have an engaged position in which the elongate shaft is axially immovable relative to the housing and a disengaged position in which the elongate shaft is axially movable relative to the housing. The release mechanism can be configured to move from the engaged position to the disengaged position in response to a force applied to move at least a portion of the release mechanism proximally relative to the housing. | 03-26-2015 |
