20080200873 | Methods and Apparatus for Infusing the Interior of a Blood Vessel - An apparatus for treating blood vessels includes an elongate body having a proximal end, a distal end, and an infusion lumen extending there-through, a plurality of infusion holes in valved communication with the infusion lumen, and a valve member which is movable inside the infusion lumen from a first position in which some of the infusion holes are blocked to a second position where fewer of the infusion holes are blocked. According to one embodiment, the valve member is a tube coaxially disposed inside the infusion lumen. According to a second embodiment, the valve member includes a seal coupled to a wire. When the wire is pulled, more holes are unsealed. In both embodiments, an inflatable occlusion balloon is coupled to the distal end of the apparatus and an inflation lumen extends from it to the proximal end of the device. A method of the invention includes determining the length of the blood vessel to be treated and adjusting the valve member to unblock a number of infusion holes corresponding to the length of the vessel to be treated. | 08-21-2008 |
20100069966 | Bone Plate System for Hand Fractures and Other Small Bones - A bone plate system for the internal fixation of metacarpal and phalanx fractures of the hand is provided. The plates are structured to permit independent reconfiguration of holes of the plates relative to a longitudinal axis and are configured to orient fasteners to interdigitate with holes displaced along the longitudinal axis. The plates are very thin, and a locking screw with a low profile head design is provided for use therewith. | 03-18-2010 |
20100069969 | Low Profile Screw and Washer System for Bone Plating - A low profile bone screw system includes a retainable washer and a low profile bone screw having a smooth conical head for insertion into the washer. The washer has an axial bore with a conical portion for fully seating the screw head and a smooth outer surface shaped like the head of a conventional compression bone screw head. Washer dispensing units are also provided. | 03-18-2010 |
20100069973 | Bending Tools for Bone Plates and Methods of Using Bending Tools - Plate shaping tools may be attached to a plate having pre-assembled guides while the plate is located on the bone to effect alteration of the plate shape in an effective and precise manner. The tools are designed such that a drill and K-wires can be inserted through the guides while the tools are coupled to the guides. | 03-18-2010 |
20100251861 | Torque-Limiting Fastener Driver - A torque-limiting fastener driver for driving a bone fastener into bone includes a handle supporting a driver shaft. The driver shaft includes limited components which are designed to provide feedback to a user regarding the applied torsional force. In addition, the driver shaft is designed to controllably fail before any potential uncontrolled failure of the distal driving tip. This prevents application of too much torque and controlled design of the shape and size of the failed components. | 10-07-2010 |
20130006311 | Method of Bending Bone Plate with Bending Tools - Plate shaping tools may be attached to a plate having pre-assembled guides while the plate is located on the bone to effect alteration of the plate shape in an effective and precise manner. The tools are designed such that a drill and K-wires can be inserted through the guides while the tools are coupled to the guides. In accord with tools disclosed and methods described, the plates are reconfigurable in shape. | 01-03-2013 |
20130204307 | Distal Radius Fracture Fixation Plate with Integrated and Adjustable Volar Ulnar Facet Support - A volar distal radius plate includes a shaft and a head. The head includes a radial side that seats below the volar rim, and an ulnar side with two extending tabs that provide a buttress support to ulnar fragments from the volar rim. The tabs are contoured to be atraumatic to the overlying soft tissue. The tabs can be readily re-orientated to better approximate the volar rim and provide close support to the volar fragments. Each tab includes a single hole specifically sized to closely receive a K-wire in a fixed angle orientation, and which permits the K-wire to apply a bending load to a tab in situ to bend the tab about a lower recess between the tab and the remainder of the head. Therefore, the plate does not require a dedicated bender. The tabs can also accommodate sutures. | 08-08-2013 |
20140061231 | Screw and Washer Dispenser System - A low profile bone screw system includes a retainable washer and a low profile bone screw having a smooth conical head for insertion into the washer. The washer has an axial bore with a conical portion for fully seating the screw head and a smooth outer surface shaped like the head of a conventional compression bone screw head. Washer dispensing units are also provided for assembling screw and washer assembled units. | 03-06-2014 |
20140330321 | METHOD OF STABILIZING A FRACTURE AT A METAPHYSIS DEFINING A CONCAVE ARTICULAR SURFACE - A volar distal radius plate includes a shaft and a head. The head includes a radial side that seats below the volar rim, and an ulnar side with two extending tabs that provide a buttress support to ulnar fragments from the volar rim. The tabs are contoured to be atraumatic to the overlying soft tissue. The tabs can be readily re-orientated to better approximate the volar rim and provide close support to the volar fragments. Each tab includes a single hole specifically sized to closely receive a K-wire in a fixed angle orientation, and which permits the K-wire to apply a bending load to a tab in situ to bend the tab about a lower recess between the tab and the remainder of the head. Therefore, the plate does not require a dedicated bender. The tabs can also accommodate sutures. | 11-06-2014 |
