20080312696 | System and Method for Polyaxially Adjustable Bone Anchorage - An implantable bone anchor assembly for fixing an elongated member such as a spinal rod may include a bone anchor, a coupling head configured to receive the bone anchor and the elongated member, and a locking mechanism. The locking mechanism may provide compressive force to simultaneously fix the position of the elongated member and lock out polyaxial rotation of the bone anchor relative to the coupling head. The locking mechanism may include an engagement member with an oblique surface configured to slide along an oblique surface of the coupling head into engagement with the elongated member. The bone anchor may comprise a head portion and a threaded portion which may be coupled with the coupling head and joined together during manufacture. The assembly may further include a pin and/or a collar to retain the bone anchor. The bone anchor may be side-loaded into the coupling head. | 12-18-2008 |

20100114105 | SYSTEM AND METHOD FOR VERTEBRAL INTERBODY FUSION - A surgical inserter and a fusion cage system which may provide for simplified fusion cage attachment and positioning. The inserter may comprise a collapsible collet with a locking rod. The fusion cage with a rectangular cross-section head may be secured to the inserter through the reverse tapered aperture of the fusion cage. The collet may be inserted into the reverse tapered aperture and the locking rod may control collapse of the collet. The collet may lock the fusion cage to the inserter allowing simplified manipulation of the collet with the inserter. The inserter with the attached fusion cage is inserted into a surgical patient. The fusion cage may be positioned within an intervertebral space. The locking rod may be withdrawn from the collet allowing collapse and withdrawal of the collet from the fusion cage leaving the fusion cage positioned between two vertebrae and the inserter withdrawn from the surgical patient. | 05-06-2010 |
20110218513 | Biologics Delivery System - A system for harvesting, preparing, and delivering biological materials or other therapeutic agents is disclosed. The system is adaptable to a variety of biological materials or other therapeutic agents. The system is adaptable for minimally invasive procedures where access may be limited. The system includes provisions for delivering biological materials or other therapeutic agents along a curved path. The system is adaptable to maximize the delivered quantity of biological materials or other therapeutic agents, thus minimizing waste. | 09-08-2011 |
20110218521 | ERGONOMIC SURGICAL INSTRUMENT HANDLE - Instrument handles isolate the functions of supporting the instrument and actuating controls on the instrument. An instrument handle may be grasped and supported by the less dexterous digits and palm of a human hand, and controls mounted on the instrument handle may be actuated by the more dexterous digits. The instrument handle may couple to an end effector so that the hand, wrist, elbow, and shoulder remain in a comfortable position when the end effector is positioned to act effectively on a selected portion of a workpiece, such as a surgical site. | 09-08-2011 |
20110270256 | SURGICAL RASP WITH RADIOFREQUENCY ABLATION - A surgical rasping system functional in multiple orthopedic applications, including but not limited to shoulder, knee, hip, wrist, ankle, spinal, or other joint procedures. The system comprises a rasping head which may be low profile and offer a flat cutting/rasping surface, and is configured to be driven by an attached hub that translates a rotational movement into a reciprocating motion. Suction for removal of bone fragments or other tissues is provided through an opening spaced apart from or adjacent to the rasping surface. A radiofrequency ablation (RF) electrode may be carried on the rasping system to provide ablation or coagulation of soft tissues. | 11-03-2011 |
20110295297 | DICE CUTTING SURGICAL INSTRUMENT - Surgical punch tools remove a waste portion of tissue from a main portion and subdivide the waste portion into two or more smaller debris portions. The tools may also grasp the waste portion or eject the debris from the tool. | 12-01-2011 |
20120029545 | RECIPROCATING SURGICAL INSTRUMENT - A surgical rasping system functional in multiple orthopedic applications, including but not limited to shoulder, knee, hip, wrist, ankle, spinal, or other joint procedures. The system may comprise a tissue removal member with a rasping head which may be low profile and offer a flat cutting/rasping surface, or with a cutting head with at least one cutting edge. The tissue removal member is configured to be driven by an attached hub that translates a rotational movement into a reciprocating motion. Suction for removal of bone fragments or other tissues is provided through an opening spaced apart from or adjacent to the rasping surface. A radiofrequency ablation (RF) electrode may be carried on the rasping system to provide ablation or coagulation of soft tissues. | 02-02-2012 |
