20090018587 | FRACTURE PLATE AND METHOD FOR FIXATION OF SAME TO A BONE SHAFT - Embodiments of the invention provide bone plates with an upper surface, a lower surface, and a longitudinal plate portion for fixation to a bone shaft. A longitudinal plate portion may have three or more non-collinear holes for locking screws, whereby the axis of at least one hole may be angled relative to the axis of another hole to improve the torsional strength of the plate-bone construct. | 01-15-2009 |
20100324603 | SYSTEM FOR RIB FIXATION - System, including methods, apparatus, and kits, for fixing ribs with bone plates. | 12-23-2010 |
20110319942 | FLEXIBLE PLATE FIXATION OF BONE FRACTURES - Embodiments provide methods, apparatuses, and systems for fixation of a fractured bone. In various embodiments, the systems and plates may provide elastic suspension of the receiving holes relative to the osteosynthesis plate. This elastic suspension may promote load distribution between the screws that connect a bone segment to the plate, thereby reducing stress risers and load shielding effect. In addition, stress at the screw holes, and within the construct as a whole, is reduced by incorporation of these elastic elements in the plate. Additionally, in some embodiments, for instance if fracture healing by callus formation is desired, elastic suspension of the receiving holes relative to the osteosynthesis plate may enable small, controlled amounts of relative motion between bone fragments connected by the plate, which may promote fracture healing by callus formation. | 12-29-2011 |
20120215265 | BONE SCREW FOR POSITIVE LOCKING BUT FLEXIBLE ENGAGEMENT TO A BONE - A fracture fixation device is described for fixing a bone having a near cortex and a far cortex, comprising a shaft portion configured to span a distance between the near cortex and the far cortex of the bone; a head portion adjoining the shaft portion and providing for engagement of the device with a bone plate, wherein the head portion is integral with the shaft portion; and a threaded front section for engagement of the device with the far cortex of the bone, wherein the device permits motion of the shaft portion relative to the near cortex. | 08-23-2012 |

20140013492 | PROTECTIVE HELMET FOR MITIGATION OF LINEAR AND ROTATIONAL ACCELERATION - Embodiments provide protective helmets configured to protect the head from linear and rotational acceleration in an impact. In various embodiments, the helmets may include an outer layer, an inner layer, and at least one intermediate layer coupled to the outer and inner layers by alternate fixation sites, thereby providing a suspension between the outer and inner layers. In various embodiments, the intermediate layer may be made from a honeycomb material, such as an aluminum honeycomb. In use, in-plane deformation of the honeycomb may allow for translation of the outer layer in a substantially tangential direction relative to the inner layer, thereby mitigating rotational acceleration imparted by the tangential impact component. Additionally, crumpling of the honeycomb in a substantially non-elastic manner may deplete impact energy to minimize the elastic rebound that can contribute to linear and rotational head acceleration, thereby mitigating linear acceleration imparted by the perpendicular impact component. | 01-16-2014 |
