Abstract: A non-lethal, hand or rifle fired grenade which widely disperses non-lethal pellets—using a flexible multipocket bladder type device which is mounted on a rigid internal frame. The grenade provides a wide distribution arc of rotation for the pellets, as the pellets are located in pockets about the bladder, which is blown outward to expel the pellets. Further, as the propellant is located within the flexible multipocket bladder, the hot gases and embers cannot escape—thereby helping to protect the target individuals from exposure to such potentially hazardous materials.

Abstract: A spinal implant and method of implanting a spinal implant that has a spacer and a plate configured to be fastened to a plurality of vertebral bodies. The plate is coupled to the spacer, with the spacer and the plate being angularly adjustable with respect to each other.

Abstract: An intervertebral spacer can have a leading end and a trailing end that includes an engaging portion configured to securely engage complementary features of an insertion tool at any of a plurality of different angles. The engaging portion can have a first radius and a major axis extending from the leading end to the trailing end. The trailing end can have a channel formed around a partially cylindrical portion having a second radius that is less than the first radius. The channel can be configured to accept an extending portion of the insertion tool.

Abstract: An intervertebral spacer includes a leading end, a trailing end comprising an opening having a clearance and a post positioned across the clearance. The post has an external surface configured to accept an extending portion of an insertion tool and to torsionally engage a complementary surface of the insertion tool at a plurality of different angles.

Abstract: A motion restoring intervertebral device includes first and second articulating components positioned between adjacent vertebrae with the articulating surface of the first component being formed by a circular domed convex projection having a first radius. The articulating surface of the second component is formed by a generally concave recess having the first radius in the medial-lateral direction and a second larger sweeping radius in the interior-posterior direction so that the components are capable of rotating against each other in all directions and translate against each other in the anterior-posterior direction, whereby translation away from the center of the first radius will produce device and joint distraction to limit excessive translation.

Abstract: A motion restoring prosthesis to be interposed between the ends of two bones adjoining a mammalian appendage or spinal joint is formed of two components with the components having inner cooperating articulating surfaces and outer bone engaging surfaces. At least one of the components has an inner section made of relatively hard, stiff material defining one or the articulating surfaces and an outer section made of a softer material defining the bone engaging surface. The softer material having a hardness/stiffness characteristic compatible with the bone to reduce stress shielding and more evenly distribute the forces from the articulating surfaces to the associate bone interface.

Abstract: A anti-splay and rod securing member for use with vertebral implants of the hook, monoaxial and polyaxial types, in which a pair of arcuate upstanding internally threaded posts define a transverse opening for securing a rod to immobilize bone segments comprises an integrally formed cap and set screw with the cap having opposed curved side walls extending around the posts and flat end walls, the set screw being positioned within the posts and free to rotate within the cap so that rotation of the set screw will advance the cap and set screw in unison along the implant posts to clamp the rod and implant together. The implant may be provided with opposed catch basins for releasably securing the distal end of a rod persuasion instrument.

Abstract: A motion restoring intervertebral prosthesis for replacing a failed or partially failed natural disc comprises two components defining an imaginary longitudinal axis generally aligned with the spinal axis when installed, the components having vertebral body engaging surfaces on one side and mating articulating surfaces on the other side, with peripheral rims encircling the articulating surfaces. The articulating surfaces accommodate rotational motion about the longitudinal axis and limited pivotal motion about the A/P and M/L planes. The rims are arranged to contact and limit the pivotal motion between the components to about +/?6° and preferably +/?4° in both directions in the M/L plane and in the A/P plane in the forward direction. Optionally, the encircling rims allow pivotal action of about 20° to 30° in the A/P plane in the rearward direction.

Abstract: A fiber optic splice closure assembly has a generally elongate casing having two generally parallel side walls, first and second end walls and a generally planar base, the side walls and end walls extending substantially perpendicular to the base. The optical fiber splice tray may include a combination of one or more: lateral pivot assemblies; longitudinal hinge assemblies; alignment bosses; buffer tube receiving channels having a buffer tube retainer; insert retention socket and insert; splice block; tier bracket hinge assembly and interlocking assembly to assist in aligning and securing a plurality of such splice trays together and to secure buffer tubes within the splice tray and assist in optical fiber dressing within the splice tray.

Abstract: A fitting and a method for facilitating clamping in a cluster a plurality of star posts to form a strainer post in a fence line, and comprising a yoke having radiating legs enclosing the star posts which are clamped to the yoke by an encircling U-bolt and recessed saddle, the yoke having slots in the ends of its spokes for capture upon the U-bolt and the saddle.
