Abstract: A transmission for a motor-powered device is herein disclosed. The transmission includes a motor input, a first output and a second output both drivable by the motor input, and a planetary gearbox. The planetary gearbox includes a first stage ring gear engaged with the first output, a second stage ring gear engaged with the second output, and a lock selectively engageable with at least one of the first stage ring gear or the second stage ring gear, the lock having an unlocked position allowing the at least one of the first stage ring gear or the second stage ring gear to power at least one of the first output or the second output and a locked position that stops rotation of the at least one of the first stage ring gear or the second stage ring gear to lock at least one of the first output or the second output.

Abstract: A heart pump configured to be placed in a heart of a patient is described. The heart pump may include an inlet configured to allow blood from the heart to enter the heart pump, an outlet configured to expel blood into the heart, a set of sensors arranged between the inlet and outlet, and at least one processor. The at least one processor may be configured to receive impedance-based signals from the set of sensors, detect a tissue located proximate to the set of sensors based, at least in part, on the impedance-based signals, determine pump information and/or a cardiac function information associated with the heart of the patient based, at least in part, the detected tissue, and output on a user interface, an indication of the pump information and/or the cardiac function information.

Abstract: One or more data streams may be used for controlling multi-system interaction. For example, a data stream may be received, and a surgical option associated with a surgical instrument may be selected based on the data stream. A control signal associated with the surgical instrument may be generated based on the selected surgical option. A surgical device may receive an external data stream from a source external to the surgical system. The device may derive, based at least on the external data stream, decision contextual information. The device may select a surgical option associated with a surgical instrument based on the decision context information. The device may generate a visual indication of the decision context information associated with selecting the surgical option. The device may generate a control signal associated with the surgical instrument based on the selected surgical option.

Abstract: A surgical system may include a processor configured to make a determination between two seemingly accurate but conflicting data streams. The processor may be further configured to obtain a first data stream associated with a measurement. The first data stream may be associated with a first control loop of the surgical system. The processor may be further configured to obtain a second data stream associated with the measurement. The second data stream may be associated with a second control loop of the surgical system. The processor may be further configured to determine that the first control loop and the second control loop are diverging. The processor may be further configured to generate a control signal based on the first and second data streams.

Abstract: Device and methods for displaying complex and conflicting interrelated data streams. An example device may receive a first biomarker value associated with a first biomarker in a first data stream and a second biomarker value associated with a second biomarker in a second data stream. The device may determine, based on the first biomarker value and the second biomarker value, that a close-loop control condition associated with a control parameter for the surgical device is failed. Based on determining that the close-loop control condition is failed, the device may identify an intraoperative metric associated with the first data stream and the second data stream. The device may generate a control signal configured to display a value associated with the intraoperative metric.
