Abstract: A suturer may include a base mechanism. The base mechanism may include a first arm having a first driving member. The base mechanism may include a second arm having a second driving member. The suturer may be configured to selectively pass a needle from an enclosed position within the first arm to an enclosed position within the second arm.

Abstract: Modular bone implants, manner of assembly, and their method of use are presented. In one form thereof, a tibial component of a knee prosthesis is providing including a tray having substantially planar top and bottom surfaces and an extension forming an elongate body having a top end and a bottom end. One of the tray and extension includes an outwardly projecting boss, with the boss having an outer wall including a cylindrical portion and a tapered portion. The other of the tray and extension includes an inwardly extending bore forming a bore wall, the bore wall including a cylindrical portion and a tapered portion.

Abstract: An intervertebral stabilization device and method is disclosed. The device preferably includes a planar spring enclosed within a housing. The housing is joined to an articulation component at either end, and the articulation components have couplings connectable to anchoring components which are securable to adjacent vertebrae. The planar spring can flex and retract providing relative motion between the adjacent vertebrae. The articulation components are ball and socket joints which allow the entire assembly to flexibly follow the curvature of the spine. A fusion rod with articulation components and couplings at either end may be substituted for the spring device. The couplings enable interchangeability between a fusion rod assembly and spring assembly, so that dynamic stabilization can occur at one vertebral level and fusion at the adjacent vertebral level. An overhung spring assembly with a sideways displaced housing which allows for a shorter pedicle to pedicle displacement is also disclosed.

Abstract: A system and method facilitate insertion of a fusion implant into the intervertebral space of a spine. The fusion implant may have a first bone engaging surface and a second bone engaging surface. An attachment interface on an insertion tool allows the implant to be releasably secured to the insertion tool, so that the insertion tool may be detached from the implant without requiring a threaded coupling. The implant may be positioned in two different orientations with respect to the insertion tool to permit usage of two different techniques to insert the implant into the intervertebral space. A recessed support member in the implant creates gaps between bone facing surfaces and the vertebral bodies such that bone graft material may occupy the gaps. The implant includes embedded radiographic markers which facilitate radiographic detection of the orientation of the implant through the surrounding tissue.

Abstract: Modular bone implants include first and second components removably attached to one another. In one embodiment, the components include a rotational alignment mechanism within the junction between the components. In another embodiment, the components include fins on each component that align without touching.

Abstract: Adjustable splints for treating bone breaks and fractures provide a variety of different options for adjusting the locations and configurations of the splints. Adjustable mounts on the splints can be moved to a variety of different locations with respect to the splint main body housings and bone connectors can be rotated into a variety of positions within the mounts. Main bodies of the splint devices can be conveniently moved with respect to each other into a variety of different configurations and positions.

Abstract: A posterior vertebral stabilizer has a resilient member such as a linear spring, which operates in tension and compression. The resilient member may be kept straight by a stabilization rod extending through the spring, or by a telescoping assembly that encases the resilient member. The ends of the stabilizer are attachable to pedicles of adjacent vertebrae so that the stabilizer adds stiffness to control flexion and extension of the vertebrae. Two such stabilizers may be used, and may be connected together by a crosslink designed to limit relative rotation of the stabilizers. Thus, the stabilizers may restrict axial rotation and lateral bending between the vertebrae, while permitting stiffened flexion and extension. Such stabilizers help provide the stiffness of a healthy intervertebral disc. In the event that fusion of the joint becomes necessary, a set screw or other component may be used to further restrict flexion and extension.

Abstract: A suture anchor includes a placement portion frangably connected to an attachment portion. The attachment portion includes an outwardly projecting barb. During insertion of the suture anchor within a bore hole formed on a bone, the barb scores at least a portion of the bone bounding the bore hole. Once the suture anchor is disposed within the bore hole, a withdrawal force is applied to the suture anchor such that the attachment portion thereof rotates within the bore hole and disconnects from the placement portion. In an alternative embodiment, the suture anchor can be formed without the outwardly projecting barb.

Abstract: A device for humane injection of fluid into animals from a distance is disclosed. The device comprises a hollow body with a primary chamber suitable for holding the fluid to be injected, a hollow needle at the forward end of the hollow body, a disposable tag attached to the forwardmost surface of the hollow body, and a remote retrieval means. The device may be projected toward the target animal by any of several conventional methods including compressed gas or chemical explosion gun. Upon impact with the target animal a trigger mechanism which comprises a ball and valve seat check valve is tripped allowing a resilient means to force the fluid through the needle and into the animal. The device is held in place during the injection process by an adhesive means on the forwardmost surface of the tag. After injection the device is pulled form the animal using the retrieval means. The tag separates from the device and remains attached to the skin marking the animal.
