Abstract: An example method includes receiving one or more physiological signals; detecting an apnea event based on the one or more physiological signals; determining that the apnea event cannot be characterized as one of a normal, OSA (obstructive sleep apnea), CSA (central sleep apnea), or combination OSA/CSA event; and outputting an electrical stimulation as a default based on determining that the apnea event cannot be characterized as a normal event, an OSA event, a CSA event, or combination OSA/CSA events.

Abstract: In some examples, a system includes a medical device comprising an elongate body configured to advance through layers of tissue of a patient, a lumen extending through the elongate body, a fluid line configured to supply fluid to the lumen, and a pressure sensor positioned within the lumen or the fluid line. The system may further include processing circuitry configured to receive, from the pressure sensor, a signal corresponding to the pressure of the fluid at each of a plurality of time points, determine, for each time point: a corresponding amplitude value of the signal, a difference between two amplitude values of the signal, an amplitude oscillation status of the signal, a position of the elongate body based on the difference and the amplitude oscillation status; and provide an indication of the position of the elongate body relative to the layers of tissue.

Abstract: Apnea events may be detected based on a primary biomarker, e.g., respiration, in the one or more physiological signals. The apnea events may be characterized as one of an obstructive sleep apnea (OSA) event, a central sleep apnea (CSA) event, or a combination OSA/CSA event based on a secondary biomarker, e.g., a frequency spectrum or a morphology of the respirations in the one or more physiological signals. A first electrical stimulation may be provided to treat OSA in response to a first one or more of the apnea events being characterized as OSA events. A second electrical stimulation may be provided to treat CSA in response to a second one or more of apnea events being characterized as CSA events. A third electrical stimulation may be provided to treat combination OSA/CSA in response to a third one or more of the apnea events being characterized as combination OSA/CSA events.

Abstract: In some examples, a tool for, e.g., creating a sub-sternal tunnel in a patient or other use, is described. The tool may include a handle and a tunneling shaft coupled to the handle. The tunneling shaft extends from a proximal end to a distal end, and at least a portion of the tunneling shaft extends in a curved orientation between the first end to the distal end. The distal end of the tunneling shaft includes a cutting tool having a sharp edge. The cutting tool is moveable from a recessed position in which the sharp edge of the cutting tool is recessed into the distal end of the tunneling shaft to a deployed position in which the sharp edge of the cutting tool extends beyond the distal end of the tunneling shaft in the deployed position, e.g., to cut pericardium, scar tissue, and/or connective tissue with the sharp edge.

Abstract: Various embodiments of a system for guiding an instrument through a region of a patient are disclosed. The system includes an instrument and a controller that is adapted to receive ultrasound image data from an ultrasound sensor, receive EM tracking data from an EM tracking system, and identify a physiological landmark of the region of the patient based on the ultrasound image data. The controller is further adapted to determine at least one of a position, orientation, or trajectory of the instrument based on the EM tracking data and generate a graphical user interface showing at least one of the position, orientation, or trajectory of the instrument in relation to a plane of the ultrasound image data, and a target zone that is registered with the physiological landmark.
