20100198268 | LOW PROFILE BONE SCREW EXTENDER AND ITS APPLICATION IN MINIMUM INVASIVE SPINAL SURGERIES - A tissue extender includes a ring defining a proximal end opening to engage a head of a subcutaneous screw, a first extender portion coupled to the ring at a proximal end of the first extender portion, and a second extender portion coupled to the ring at a proximal end of the second extender portion. The first extender portion includes a first coupling portion disposed at a distal end of the first extender portion, and the second extender portion includes a second coupling portion at a distal end of the second extender portion. The first and second extender portions define two side openings disposed on opposite sides of the tissue extender. The distal ends of the first and second extender portions together define a distal end opening. The first coupling portion engages the second coupling portion when the tissue extender is in an extended state. The distal end opening is larger in the extended state than in an unextended state. | 08-05-2010 |

Some of these have locking mechanisms as alternatives to conventional set screws. Some of these use ratcheting systems for securing the elongated support structure. Some of these are multi-axial systems. Some of these are alternatives to conventional systems. | 11-18-2010 |
20110028979 | Spinal Implant Clearing Gouge - A surgical gouge for clearing bone and soft tissue from around a previously implanted rod during a surgical operation. The gouge includes an elongate handle with a distally positioned cutting member at one end. The cutting member has a rod capture arm with an arcuate surface generally conforming to the cylindrical shape of the rod. The cutting member further having a curved leading cutting blade extending over and about the rod capture arm. The curved leading cutting blade configured so as to create a trough between the inside surface of the curved leading cutting blade and the rod capture arm to capture any cut bone and/or soft tissue from around the rod as the gouge is rotated about the rod. The curved cutting blade having a distal end sharpened at its distal edge to enable the user to cut away bone and soft tissue from around the rod. It may also be desirable for the distal end to have sharpened side edges to assist in cutting away the bone and soft tissue that have built up about the rod. | 02-03-2011 |
20110106165 | DEVICES AND METHODS FOR DYNAMIC SPINAL STABILIZATION AND CORRECTION OF SPINAL DEFORMITIES - An apparatus for attachment to a vertebral body for correcting spinal deformities. The apparatus has a plate member having an upper surface and a lower surface. The upper surface having at least one receiving member defining a channel for receiving a flexible connection member. The at least one receiving member having a proximal portion and a distal portion. The proximal and distal portions interfacing along a frangible connection such that the at least one receiving member extends axially from the upper surface a first distance when the frangible connection is unbroken and the at least one receiving member extends axially from the upper surface a second distance when the frangible connection is broken. The second distance is less than the first distance. | 05-05-2011 |
20110106178 | PEDICLE SCREW HEAD EXTENDER - The present invention relates to pedicle screw spinal rod connectors and more specifically, a pedicle screw head extender for use with a pedicle screw to ease connection to a spinal rod. The pedicle screw head extenders provided herein can be used with either fixed head pedicle screws or multi-axial head pedicle screws. The pedicle screw head extenders can either be threaded to or snapped into place within the various pedicle screws. It may also be possible to use the present invention with other types of spinal screws that may be connected to spinal rods without the screw actually being implanted through the pedicle of the spine. | 05-05-2011 |
20110112643 | Hybrid Intervertebral Spinal Fusion Implant - An implant made of at least two different materials. The implant may include materials with varying radiolucency and mechanical properties. Such a hybrid implant may offer controlled radiographic visibility and optimized structural properties for implant placement, including placement for use in spinal arthrodesis. | 05-12-2011 |
20110184522 | MODULAR INTERBODY DEVICES AND METHODS OF USE - Methods and devices for spacing vertebral members using modular intervertebral devices and insertion tools. The devices may include opposing first and second endplates, and an intermediate member configured to fit between and support the endplates. The insertion tool may include an elongated handle and a distracter. A method of inserting the device using the tool may include inserting the endplates positioned on opposing sides of the handle into the intervertebral space and positioning the endplates in the intervertebral space relative to first and second vertebral members. The method may include deploying the distracter and increasing a distance between the endplates. Another step may include inserting the intermediate member into the intervertebral space and between the endplates and supporting the endplates with the intermediate member. The insertion tool may then be removed from the intervertebral space. | 07-28-2011 |
20120029571 | Adjustable Connector for Interconnecting Elongate Rod Members at Variable Angular Orientations - An adjustable connector including first and second connector members rotationally coupled together and configured to receive first and second spinal rods, respectively. In one embodiment, the first connector member includes an elongated slot that receives the first rod and has a length extending along an axis arranged transverse to the rotational axis, and the second connector member includes a second passage that receives the second rod. A lock member is positioned between the connector members and includes an angled rod bearing surface extending along a plane oriented at an oblique angle relative to the rotational axis. A compression member extends into the first passage of the first connector member and into compressed engagement with the first rod to displace the first rod along the length of the elongated slot and into sliding engagement with the angled rod bearing surface, which in turn axially displaces the lock member toward the second connector member to compress the first interface surface of the lock member against an opposing second interface surface to selectively prevent relative rotation between the connector members. | 02-02-2012 |
