Patent number: 11896319Abstract: Systems and methods for medical object tracking are provided. The system may include a plurality of radio frequency transceivers that each emit a radio frequency signal at a first respective frequency. The system may further include a radio frequency beacon that is attachable to the medical object and that emits a second radio frequency signal at a second respective frequency different than the first respective frequency in response to receiving the radio frequency signal. The system may also include a control device in communication with the plurality of radio frequency transceivers, the control device including processing circuitry that determines a location of the medical object in three-dimensional space based at least in part on the second radio frequency signal. The beacon may include a platform, a first fixation element that extends from the platform; and a second fixation element that is tilted relative to the first fixation element.Type: GrantFiled: September 1, 2022Date of Patent: February 13, 2024Assignee: CAIRA SURGICALInventor: Morteza Meftah

Publication number: 20230270506Abstract: A system for alerting a medical provider of a possible displacement of a beacon includes the beacon, a control device, and a transceiver. The beacon includes sensors (for example, but not limited to, an IMU and a frequency shifter) and at least one antenna that exchanges signals with the transceiver. The IMU and the frequency shifter are used in a coordinated way to alert the medical provider if the beacon has been displaced in a way that might impact the medical procedure. As the beacon moves, when an anomalous correlation between the change over time of the IMU position data (of the beacon) and the frequency shifter position data (of the beacon) is detected, and the beacon has undergone a gravity/inertial moment (according to the IMU data) that exceeds a pre-selected threshold, the medical provider is alerted that the beacon's position might have shifted enough to impact the medical procedure.Type: ApplicationFiled: March 21, 2023Publication date: August 31, 2023Inventors: Gordon L. GOODCHILD, Morteza MEFTAH

Publication number: 20230123013Abstract: Systems and methods for radio-frequency-based location determination in a draped environment can include an active beacon and a control device in communication with a plurality of radio frequency (RF) transceivers. The RF transceivers can be configured to emit an RF signal responsive to transmission instructions from the control device. The active beacon can be configured to transmit a modified RF signal responsive to receipt of the RF signal from any of the plurality of RF transceivers, where the frequency value of the signal from the active beacon is shifted by an amount from the received RF signal. The plurality of RF transceivers then receive the modified RF signals. The control device can be configured to determine a location of the active beacon based upon the received modified RF signals. The draped environment can include draping material that is substantially transparent to the RF signals.Type: ApplicationFiled: December 21, 2022Publication date: April 20, 2023Inventors: Morteza MEFTAH, Gordon L.
