    Abstract: A fixation component includes tines extending from a base portion of the fixation component. Each tine is elastically deformable between a pre-set position and an open position. Each tine includes a hook segment extending from a proximal end near the base portion to a distal end. Each tine also includes a distal segment extending from the distal end of the hook segment to a tissue-piercing tip. When positioned in the pre-set position, the hook segment extends along a pre-set curvature that encloses an angle between 135 degrees and 270 degrees, and the distal segment extends away from a longitudinal axis of the fixation component.

    Abstract: In some examples, a medical system includes a medical device. The medical device may include a housing configured to be implanted in a target site of a patient, a light emitter configured to emit a signal configured to cause a fluorescent marker to emit a fluoresced signal into the target site, and a light detector that may be configured to detect the fluoresced signal. The medical system may include processing circuitry configured to determine a characteristic of the fluorescent marker based on the emitted signal and the fluoresced signal. The characteristic of the fluorescent marker may be indicative of a presence of a compound in the patient, and the processing circuitry may be configured to track the presence of the compound of the patient based on the characteristic of the fluorescent marker.

    Abstract: Various embodiments of a hermetically-sealed package and a method of forming such package are disclosed. The package can include a housing having an inner surface and an outer surface, and a non-conductive substrate hermetically sealed to the housing. The package can also include a light source disposed on a first major surface of the substrate and adapted to emit light through the first and second major surfaces of the substrate, and a detector disposed on the first major surface of the substrate and adapted to detect the light emitted by the light source.

    Abstract: This disclosure is related to devices, systems, and techniques for performing patient parameter measurements. In some examples, a medical device system includes an optical sensor configured to measure ambient light and a tissue oxygen saturation parameter and processing circuitry configured to determine that a current measurement of the tissue oxygen saturation parameter is prompted and control the optical sensor to perform an ambient light measurement associated with the current measurement of the tissue oxygen saturation parameter. The processing circuitry is further configured to determine, based on the ambient light measurement, at least one of whether to control the optical sensor to perform the current measurement of the tissue oxygen saturation parameter, when to control the optical sensor to perform the current measurement of the tissue oxygen saturation parameter, or whether to include the current measurement of the tissue oxygen saturation parameter in a trend of the tissue oxygen saturation parameter.

    Abstract: Systems, devices, and techniques for establishing communication between two medical devices are described. In one example, an implantable medical device comprises communication circuitry, therapy delivery circuitry, and processing circuitry configured to initiate a communication window during which the implantable second medical device is capable of receiving the information related to a cardiac event detected by a first medical device, the communication window being one of a plurality of communication windows defined by a communication schedule that corresponds to a transmission schedule in which the first medical device is configured to transmit the information, control the communication circuitry to receive, from the first medical device, the information related to the cardiac event that is indicative of a timing of the cardiac event with respect to a timing of the communication window, schedule and control delivery of a therapy according to the information related to the cardiac event.

    Abstract: A method and medical device for detecting signals that detects emitted light scattered by a volume of tissue delivered along a first pathway at a plurality of wavelengths to generate corresponding first detected light intensity output signals, detects emitted light scattered by the volume of tissue delivered along a second pathway different from the first pathway at a plurality of wavelengths to generate corresponding second detected light intensity output signals, determines whether a difference between the emitted light detected along the first pathway and the emitted light detected along the second pathway is greater than a predetermined threshold, and alters sensing by the device in response to the determining whether a difference is greater than the predetermined threshold.
