  • Patent number: 11406433
    Abstract: Embodiments provide methods, apparatuses, and systems for fixation of a fractured bone with a bone plate. In various embodiments, the systems and plates provide elastic suspension of the receiving holes relative to an osteosynthesis plate. This elastic suspension can 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 where fracture healing by callus formation is desired, elastic suspension of the receiving holes relative to the osteosynthesis plate can enable small, controlled amounts of relative motion between bone fragments connected by the plate. This relative motion can promote fracture healing by callus formation.

  • Publication number: 20210259712
    Abstract: Embodiments herein employ a flexible orthopedic alignment guide for surgical implantation of flexible bone plates. Specifically, the alignment guide is designed to be used in conjunction with flexible bone plates whereby flexible sections of the alignment guide aid in alignment of drill bits and fasteners with the fastener holes of the bone plate. The flexible guide is designed to flex in a similar manner to the bone plate, thus maintaining positive engagement without compromising hole alignment.

  • Publication number: 20210007070
    Abstract: Auto-recovery from RF signal acquisition failure may be provided in a portable computing device. A field-calculated frequency-temperature (“FT”) curve is used to apply temperature compensation to a crystal oscillator associated with RF transceiver circuity of the device. In response to acquisition failure, it may be determined whether a deviation between the field-calculated FT curve and a factory-set FT curve exceeds threshold criteria. In response to acquisition success, the field-calculated FT curve may be refined based on frequency error information. However, in response to acquisition failure and a determination that the deviation exceeds the threshold criteria, information defining the field-calculated FT curve may be replaced with information defining the factory-set FT curve.

  • Patent number: 10834987
    Abstract: Embodiments herein employ a novel strategy based on a floating cellular liner that acts as a torsional suspension system to dampen rotational acceleration, such as head acceleration in a helmet, in response to an oblique impact. Specifically, the torsional suspension consists of an anisotropic cellular liner that is at least partially recessed inside a more rigid adjacent shell, relative to which the cellular liner can simultaneously undergo translation and in-plane compression.

  • Patent number: 10070905
    Abstract: A device can be provided that includes a bone plate having an upper surface and a bone-facing surface, wherein the bone plate includes one or more openings extending through the bone plate from the upper surface to the bone-facing surface, and one or more sliding elements each including a fastener receiving hole. The one or more openings can at least partially surround a periphery of one of the receiving holes. Further, the one or more openings can be at least partially filled with an elastomer to support elastic suspension of the one or more sliding elements in the bone plate, thereby enabling relative displacement between the one or more sliding elements and the bone plate. At least one sensor can also be provided that is operable to assess a dynamic parameter of one of the one or more sliding elements within the bone plate.

  • Patent number: 10022168
    Abstract: Embodiments provide a method and device for plate osteosynthesis of a bone fracture that allows angle-stable fixation of the bone fracture, while permitting elastic axial motion at the fracture site in a controlled, symmetric manner to stimulate fracture healing. Embodiments pertain to a bone plate having an outer surface and a bone-facing surface. The bone plate incorporating internal sliding elements containing a threaded receiving hole for bone screws that have a correspondingly threaded screw head. The sliding elements undergo controlled displacement parallel to the longitudinal axis of the plate but are substantially constrained against displacement perpendicular to the longitudinal axis of the plate. The bone screws with threaded heads may be rigidly fixed to the threaded receiving holes in the sliding elements without compressing the bone plate onto the hone surface. Sliding elements are elastically suspended inside the bone plate and undergo dynamic motion.
