Abstract: A multiaxial receiver may include a body having a U-shaped cavity configured to receive a longitudinal rod therein and a lower cavity configured to couple to a pedicle screw. The multiaxial receiver may include a first passageway configured to permit a tether to pass therethrough in the vertical direction. In some embodiments, the multiaxial receiver may also include a second passageway configured to permit a tether to pass therethrough in the horizontal direction. An immobilization assembly including a set screw and a wedge may immobilize the tether. The immobilization assembly may be configured to be rotated from an open position in which the tether is permitted to pass through the first passageway to a closed position in which the tether is immobilized within the first passageway or second passageway by pining the tether against a bearing surface of the first passageway.

Abstract: An intraoperative ultrasound imaging system and method capable of using ultrasound imaging to safely place a surgical access instrument (e.g. guide wire, dilator, cannula, etc.) through a tissue (e.g., muscle, fat, brain, liver, lung, etc.) without damaging nearby neurovascular structure is described herein. The intraoperative ultrasound system includes an ultrasound probe assembly configured for emitting and receiving ultrasound waves and a computer system including a processor and a display unit. Once the probe is in position, ultrasound imaging is performed wherein the computer receives RF data from the probe and causes a B-mode image of the visible anatomical structures (e.g. muscle, bone, etc.) to be displayed on the display unit.

Abstract: A system and method for filtering collected data in connection with tracking the use of resources of a computer is disclosed. Embodiments of the system comprise a plurality of client computers, wherein each computer has one or more resources that the system tracks; a client application for each client computer, each client application for collecting utilization duration data relating to the utilization of the resources of the application's corresponding client computer; an application server for receiving the utilization duration data collected by the client applications and for storing the received data in a storage structure; wherein each client application has a filter for filtering data collected by the client application.

Abstract: Some embodiments of the invention provide a method for tracking the use of software resources of a computer. This method identifies an instance when a particular software resource is used. It then measures and records a time period relating to the detected utilization of the software resource. In some embodiments, this time period is an estimated duration of the utilization of the software resource.

Abstract: Some embodiments of the invention provide a system for tracking utilization of resources of computers. This system includes several client computers, where each computer has one or more resources that the system tracks. The system also includes a client application for each client computer. Each client application collects utilization duration data relating to the utilization of the resources of its corresponding client computer. The system further includes an application server that receives the utilization duration data collected by the client applications and stores the received data in a storage structure. In certain embodiments, the collected duration data includes time periods that the client applications measure. The application server then aggregates and/or stores the collected time periods.
