Abstract: Intramedullary systems, expandable intramedullary nails, expandable anchors, and methods of using the same. The intramedullary system may include an expandable intramedullary nail configured to extend into an intramedullary canal of a long bone and/or one or more expandable anchors configured to extend at an angle transverse to the intramedullary nail. The intramedullary nails and/or anchors may include one or more integrated expansion mechanisms that allow for insertion in a contracted configuration and expansion into a deployed configuration to lock the relative position and prevent axial rotation and translation of the system.

Abstract: Devices, systems, and methods for bone stabilization, especially proximal humeral stabilization. The stabilization system may include a bone plate having an elongated portion extending along a longitudinal axis and an enlarged head portion extending from the elongated portion. The stabilization system may include an intramedullary nail having an upper portion and a lower portion extending from the upper portion, the upper portion and the lower portion including a plurality of holes. A plurality of fasteners may be configured to extend through one or more of the plurality of through holes in the bone plate and/or one or more of the plurality of holes in the intramedullary nail and into the bone. The plate and nail may each be used alone or in combination together to stabilize a fracture in a long bone, such as a humerus.

Abstract: A first sensor node 100 includes a radio for wireless communications; a sensor module 204 to sense a selected parameter; and a scheduler 228 that selects a listen time for the first sensor node, such that, during the listen time, the radio is activated and able to receive wireless signals and, during a time other than the listen time, the radio is deactivated and unable to receive wireless signals, and causes transmission to a second sensor node of a first message. The first message includes a time offset from a transmission time of the first message, the time offset indicating a timing of a first listen time for the first sensor node. The first node 100 receives, from the second sensor node, a responsive second message including a time based on the time offset to transmit the second message.

Abstract: In one embodiment, a first sensor node 100 includes a radio to effect wireless communications; a sensor module 204 to sense a selected parameter; and a scheduler 228 that selects a listen time for the first sensor node, such that, during the listen time, the radio is activated and able to receive wireless signals and, during a time other than the listen time, the radio is deactivated and unable to receive wireless signals, and causes transmission to a second sensor node a first message. The first message includes a time offset from a transmission time of the first message, the time offset indicating a timing of a first listen time for the first sensor node. In response, the node 100 receives, from the second sensor node, a second message, with the time selected by the second sensor node to transmit the second message to the first sensor node being based on the time offset.
