This invention is directed to orthopedic implants and systems. The invention also relates to methods of implant design, manufacture, modeling and implantation as well as to surgical tools and kits used therewith. The implants are designed by analyzing the articular surface to be corrected and creating a device with an anatomic or near anatomic fit; or selecting a pre-designed implant having characteristics that give the implant the best fit to the existing defect.

Embodiments of the present invention comprise a system for positioning a drawn implement having a transverse tool bar being pulled by a vehicle traveling generally along a desired path of movement, the vehicle having a mounting hitch on the rear end thereof where a system hitch is configured to adjust its angular orientation and that of the tool bar relative to the vehicle mounting hitch and a global positioning system having an antenna mounted on the system hitch operable to detect the position of the tool bar of the implement relative to the desired path as the vehicle moves generally along the desired path and generate a signal that is indicative of the lateral position of the implement relative to the desired path and means for controlling the hitch means to adjust the angular orientation of the hitch means and the tool bar so that the implement follows the desired path of movement in response to the global positioning system signals.

A device for reducing migration of a pin of an intramedullary fixation device, especially to reduce migration of a clavicle pin introduced in the medullary canal of the clavicle to fix a fractured clavicle bone. A clavicle nail with a curved tip is inserted within the medullary canal of the clavicle. The back end of the nail that extends out of the clavicle is provided with indentations or grooves. The back end of the nail is received in a hollow cavity of a cap, which locks onto the indentations or grooves of the nail. A screw is placed through an eyelet of the cap and turned into the clavicle to secure the cap to the clavicle. As a result, the nail is fixed within the medullary canal and undesirable migration of the pin within the medullary canal is reduced.

The present invention relates to an apparatus for rapidly analyzing frame(s) of digitized video data which may include objects of interest randomly distributed throughout the video data and wherein said objects are susceptible to detection, classification, and ultimately identification by filtering said video data for certain differentiable characteristics of said objects. The present invention may be practiced on pre-existing sequences of image data or may be integrated into an imaging device for real-time, dynamic, object identification, classification, logging / counting, cataloging, retention (with links to stored bitmaps of said object), retrieval, and the like. The present invention readily lends itself to the problem of automatic and semi-automatic cataloging of vast numbers of objects such as traffic control signs and utility poles disposed in myriad settings. When used in conjunction with navigational or positional inputs, such as GPS, an output from the inventative systems indicates the identity of each object, calculates object location, classifies each object by type, extracts legible text appearing on a surface of the object (if any), and stores a visual representation of the object in a form dictated by the end user / operator of the system. The output lends itself to examination and extraction of scene detail, which cannot practically be successfully accomplished with just human viewers operating video equipment, although human intervention can still be used to help judge and confirm a variety of classifications of certain instances and for types of identified objects.

A device that includes a scaffold composition and a bioactive composition with the bioactive composition being incorporated into or coated onto the scaffold composition such that the scaffold composition and / or a bioactive composition controls egress of a resident cell or progeny thereof. The devices mediate active recruitment, modification, and release of host cells from the material.

Device and method significantly that improves the safety and procedural success of the existing art by being able to be less traumatic to vascular tissue, improving atrial contact with the ablation surface, improving positioning and geometrical precision of the ablation pattern, improving steerability and deliverability of the ablation device and by improving localization and geometric precision of the ablation device. The risk of pulmonary vein fibrosis / stenosis will also be substantially lowered. Finally, expansion of the eligible atrial fibrillation population will inherently increase due to the improved components and methods of the present invention.
