20100076443 | DRILLING/MILLING GUIDE AND KEEL CUT PREPARATION SYSTEM - An instrument system, associated milling or drilling guide and method include use of a trial implant of a size corresponding to an actual implant for the intervertebral space, with a milling guide mounted on the trial implant. The milling guide includes a longitudinal guide chamber which is tapered from a forward end to a rearward end. The system also includes a cutting tool which is received in the guide chamber in order to form a cutout in an adjacent vertebra. This cutting tool includes a bearing member which pivotally engages the rearward end to form a pivot axis for the cutting tool in the tapered guide chamber. Either the milling guide can be inverted to form the cutout in the other vertebra; or the milling guide can be provided with two guide chambers, to be used with one cutting tool moved between them or two respective cutting tools. | 03-25-2010 |
20100168860 | ORTHOPEDIC IMPLANT WITH FLEXIBLE KEEL - A flexible keel is provided for use as a bone anchoring element for use with a range of orthopedic implants having portions configured for anchoring into boney tissue. The flexible keel includes two wings terminating proximally in a pair of outward flares, the wings further spaced from a bone contacting implant surface by a void. The flexibility of the keel wings increases the ease of revision or explantation procedures. | 07-01-2010 |
20100280620 | TRIAL IMPLANT ASSEMBLY - A trial implant assembly is provided that includes a threaded shaft having exterior threading adjacent a distal end and a trial implant that includes a trial base having an interiorly threaded through hole couplable to the distal end of the shaft and a trial head having a superior endplate and an inferior endplate and a support connecting the superior endplate to the inferior endplate. A variety of visualization windows are provided through the trial implant as well as a variety of mechanically adjustable stops to prevent over insertion of the trial head within the intervertebral disc space. | 11-04-2010 |
20100324683 | INTERVERTEBRAL IMPLANT - An intervertebral implant that is configured to be inserted into an intervertebral space along a direction of insertion is provided. The intervertebral space is defined by a superior vertebral body and an inferior vertebral body that are opposed in a transverse direction. The intervertebral implant may include a body and a first keel. The body may have first and second opposing outer surfaces that are each configured to engage one of the superior and inferior vertebral bodies. The first keel may extend out from the first outer surface in an outward direction and may define a lateral width that increases with respect to an outward direction along the first keel such that an outer portion of the first keel is wider than an inner portion of the first keel. The lateral width may be substantially transverse to the insertion direction and the outward direction. | 12-23-2010 |
20110087331 | ARTICULATING DISC IMPLANT - An intervertebral disc implant for use in the spine including a first part ( | 04-14-2011 |
20130079783 | DRILLING/MILLING GUIDE AND KEEL CUT PREPARATION SYSTEM - An instrument system, associated milling or drilling guide and method include use of a trial implant of a size corresponding to an actual implant for the intervertebral space, with a milling guide mounted on the trial implant. The system also includes a cutting tool which is used to form a cutout in an adjacent vertebra. | 03-28-2013 |
20140100658 | ARTICULATING INTERVERTEBRAL IMPLANT - An intervertebral disc implant for use in the spine includes a superior endplate and an inferior endplate. The superior endplate is configured to articulate about the inferior endplate in an anterior-posterior direction during flexion and extension. The superior endplate is further configured to axially rotate about the inferior endplate during axial rotation, and is further configured to articulate about the inferior endplate along a medial-lateral direction during lateral bending. During axial rotation, the superior endplate is induced to articulate about the inferior endplate along the medial-lateral direction. During lateral bending, the superior endplate is induced to axially rotate about the inferior endplate. | 04-10-2014 |

20100037578 | HEIGHT OF CUT ADJUSTMENT MECHANISM FOR ROTARY CUTTING DECK - A height of cut adjustment mechanism is provided for a rotary cutting deck mounted on a lift arm extending from a traction vehicle. The mechanism includes a front axle and a rear axle, at least one roller mounted on each axle, and a pair of height of cut arms extending from each axle to a pivot axis on the rotary cutting deck. A notch lock on each height of cut arm may be moved between a locked position in which the notch lock engages a notch plate at a desired cutting height, and an unlocked position in which the notch lock disengages the notch plate so that the height of cut arm can pivot with respect to the rotary cutting deck. A lever attached to each notch lock can be operated to move the notch lock between the locked and the unlocked positions. | 02-18-2010 |
20100037581 | LATCH MECHANISM FOR RETAINING GRASS CATCHER ON REEL MOWER CUTTING UNIT - A latch mechanism is disclosed that retains a grass catcher on a reel mower cutting unit. The latch mechanism includes a latch plate releasably holding a rod end of the grass catcher in a slot on the reel mower cutting unit. The latch plate pivots on a horizontal axis. A clip is fastened to the horizontal axis to lock the latch plate in either a locked position retaining the grass catcher or an unlocked position allowing removal of the grass catcher. | 02-18-2010 |
20100107586 | GRASS CATCHER RETAINING DEVICE FOR REEL MOWER CUTTING UNIT - A grass catcher retaining device is disclosed for a reel mower cutting unit. The retaining device includes a central support ring on the grass catcher and removably fastened to a loop projecting forwardly from a lift arm for the reel mower cutting unit. The central support ring may be pivotably mounted to the top of the grass catcher, and may have a gate that is spring biased to the closed position to engage a wireform loop extending forwardly from the lift arm that supports the reel mower cutting unit. Additionally, a rod may extend horizontally from the sides of a grass catcher and may be pivotably attached to the reel mower cutting unit. | 05-06-2010 |
20110192129 | HEIGHT OF CUT ADJUSTER ASSEMBLY FOR REEL MOWER CUTTING UNIT WITH REMOVABLE ATTACHMENT - A height of cut adjuster for a reel mower cutting unit with a removable attachment includes a front roller with a shaft positionable in front of the cutting reel axis, and a roller bracket assembly having a bottom bracket removably attached to a top bracket to provide a gap therebetween where the front roller shaft is held. The roller bracket assembly may be pivoted, and the top bracket may be connected to the bottom bracket in a different position further from the cutting reel, so that an attachment such as a conditioner may be installed between the front roller and the cutting reel. | 08-11-2011 |
20110213530 | AERATOR HAVING FLEXIBLE FRAME - An aerator having a flexible frame for use on sloped or undulating ground surfaces of golf courses and other turf. The aerator includes a pair of frame sections linked together at a horizontal pivot axis, one of the frame section supporting a coring head. A ground sensor is pivotably attached to one of the frame sections so that the ground sensor may pivot in response to changes in ground slope and provide output relating to the magnitude of the change. Based on the output, a flex frame actuator pivots the pair of frame sections with respect to each other. | 09-01-2011 |
