Abstract: This disclosure is directed to devices, systems, and techniques for identifying a respiration rate based on an impedance signal. In some examples, a medical device system includes a medical device including a plurality of electrodes. The medical device is configured to perform, using the plurality of electrodes, an impedance measurement to collect a set of impedance values, where the set of impedance values is indicative of a respiration pattern of a patient. Additionally, the medical device system includes processing circuitry configured to identify a set of positive zero crossings based on the set of impedance values, identify a set of negative zero crossings based on the set of impedance values, and determine, for the impedance measurement, a value of a respiration metric using both the set of negative zero crossings and the set of positive zero crossings.

Abstract: In some aspects, systems, devices, and techniques for programming a medical fluid delivery device are described. In one example, the disclosure relates to a system including a medical fluid delivery device configured to deliver a therapeutic agent to a patient, and a processor. The processor may be configured to receive a proposed therapy dosing program that defines a fluid therapy for delivery to a patient via a medical fluid delivery device for a first period of time, determine a total dosage over a second period of time, where the second period of time at least partially overlaps the first period of time, and compare the total dosage over the second period of time to a reference dosage.

Abstract: A device, system, and method for ligating the left atrial appendage without creating pro-arrhythmic tissue. The device may generally include a snare including a thermally transmissive distal portion and a suture including a distal portion, both distal portions having a lasso-shaped configuration that may be positioned proximate the base of the left atrial appendage. Once the distal portions of the snare and the suture are tightened around the base of the left atrial appendage, the thermally transmissive distal portion of the snare may be activated to create an ablation lesion in adjacent left atrial appendage tissue. The lesion may be created with radiofrequency energy or through cryoablation by the circulation of refrigerant within the thermally transmissive distal portion of the snare.
