At least one bronchial nerve is stimulated with electrical energy. The electrical signals from the at least one bronchial nerve are recorded to provide a first value representative of nerve function. Cryogenic treatment energy is applied to form ice in the bronchus having a thickness to encapsulate the at least one bronchial nerve to cause a reduction in nerve function. The at least one bronchial nerve is restimulated with electrical energy. The electrical signals are recorded from the restimulated at least one bronchial nerve to provide a second value that represents diminished nerve function. The first value and the second value are compared to provide an assessment of the reduction in nerve function.

SYSTEMS AND METHODS FOR NON-CONTACT RESPIRATORY MONITORING
Methods and systems for non-contact monitoring of a patient to determine respiratory parameters such as respiration rate, tidal volume, minute volume, oxygen saturation, and other parameters such as motion or activity. The systems and methods receive a first, video signal from the patient and from that extract a distance or depth signal from the relevant area to calculate the parameter(s) from the depth signal. The systems and methods also receive a second, light intensity signal from an IR feature projected onto the patient, and from that calculate the parameter(s) from the light intensity signal. The parameter(s) from the two signals can be combined or compared to provide a qualified output parameter.
In a body area network (BAN), a patient is implanted with multiple implantable medical devices (IMDs), with various amounts of limited local memory. There may be more therapeutic benefit in storing data from some classes of IMDs than other, or memory storage resources of one IMD may be under-utilized while memory storage resources of another IMD are full. A first IMD may store data of the first IMD on local memory of a second IMD. In this manner, in the event the first IMD memory is full, rather than overwriting locally stored data, the first IMD may off-load additional data for local storage in the second IMD. For instance, the memory of the second IMD may be under-utilized or there may be more therapeutic benefit in storing the data of the first IMD that storing data of the second IMD.

SYSTEM FOR DETERMINING THAT VENTRICULAR TACHYARRHYTHMIA IS PREDICTED
A medical device system includes an implantable medical device configured to sense cardiac electrogram data and processing circuitry. The processing circuitry is configured to identify a premature ventricular contraction event within the cardiac electrogram data. The processing circuitry is configured to determine, for at least one or more cardiac cycles associated with the premature ventricular contraction event, one or more periodic repolarization dynamics metrics based on the cardiac electrogram data. The processing circuitry is configured to determine, for at least the one or more cardiac cycles associated with the premature ventricular contraction event, one or more turbulence metrics based on the one or more periodic repolarization dynamics metrics. The processing circuitry is configured to determine whether to provide an indication of at least one of sudden cardiac arrest or ventricular tachyarrhythmia based on the one or more periodic repolarization dynamics metrics and the one or more turbulence metrics.
In general, devices, systems, and techniques are described for adjusting one or more parameters defining adaptive stimulation therapy. In one example, a system includes processing circuitry configured to receive sensed data indicative of bioelectric brain signals sensed during delivery of brain stimulation therapy to a patient, receive event data indicative of an event experienced by a patient during delivery of the brain stimulation therapy, identify a subset of the sensed data based on the event data, and determine, based on the subset of the sensed data and the event data, a range of values for at least one threshold defining subsequent brain stimulation therapy, the range of values determined to reduce an occurrence of the event during delivery of the subsequent brain stimulation therapy. A medical device may be controlled to deliver the subsequent brain stimulation therapy according to the at least one threshold within the range of values.

OPERATION OF A MEDICAL DEVICE SYSTEM TO IDENTIFY PARTICULAR CARDIAC DATA SAMPLES ASSOCIATED WITH A CARDIAC EVENT
An example system includes a memory configured to store a plurality of sets of cardiac data, each set of cardiac data of the plurality of sets of cardiac data is associated with a patient; and processing circuitry in communication with the memory, wherein the processing circuitry is configured to: cause a user interface to display a set of cardiac data of the plurality of sets of cardiac data, wherein the set of cardiac data includes a plurality of cardiac data samples, and wherein each cardiac data sample is associated with a cardiac event probability that the cardiac data sample is associated with a cardiac event; receive, from the user interface, a user selection of a cardiac event probability threshold corresponding to the cardiac event; and cause the user interface to indicate each cardiac data sample associated with a cardiac event probability that is greater than the cardiac event probability threshold.
An example system includes a light source configured to emit light towards a tissue of a patient, a detector configured to detect the light emitted by the light source after the light passes through the tissue of the patient, and a controllable mask disposed between the detector and the tissue of the patient. The controllable mask is configured to block a first portion of the light passing through a first portion of the tissue and transmit a second portion of the light passing through a second portion of the tissue. The system also includes processing circuitry configured to determine a physiological characteristic of the patient based on the second portion of the light.
Example systems, devices, and techniques are described. An example system includes one or more memories configured to store, for each patient of a plurality of patients, a set of flagged cardiac data signal segments and a reference cardiac data signal segment. The system includes processing circuitry coupled to the one or more memories. The processing circuitry is configured to receive, from a user device, a user input indicating a user selection of a patient of the plurality of patients. The processing circuitry is configured to cause the user device to display the reference cardiac data signal segment corresponding to the patient and a first flagged cardiac data signal segment of the set of flagged cardiac data signal segments corresponding to the patient at a same time, wherein the displayed reference cardiac data signal segment and the displayed first flagged cardiac data signal segment do not overlap.
This disclosure generally relates to systems, devices, and methods configured to provide adjustment to tachyarrhythmia detection and noise reversion pacing therapy to, for example, avoid delivery of noise reversion pacing therapy during a tachyarrhythmia. For example, VT/VF detection parameters may be adjusted and ventricular capture may be determined upon determination of noise that initiates noise reversion pacing therapy. Further, for example, noise reversion pacing therapy may be adjusted or disabled in response to detection of a VT/VF episode and/or in response to confirmation of a VT/VF episode received from an external device.
Prosthetic heart valve delivery systems are disclosed that have a stop that inhibits the system from passing beyond the point of no return where further deployment of a collapsed prosthetic heart valve may render it unable to be recaptured. An elongate catheter may include an outer cover configured to cover and uncover a collapsed prosthetic heart valve. The collapsed prosthetic heart valve is biased to expand radially outward as the outer cover uncovers the collapsed prosthetic heart valve. The system may also include a screw shaft and an actuator rotatable about the screw shaft to cause axial translation of a carriage, and thus the connected outer cover. The stop inhibits further rotation of the actuator, and thus further axial translation of the outer cover, and thus further deployment of the collapsed prosthetic heart valve.
