Abstract: An example system includes memory configured to store a plurality of lead impedances (LeadZs) and processing circuitry communicatively coupled to the memory. The processing circuitry is configured to determine a first sensed LeadZ, and determine a second sensed LeadZ. The processing circuitry is configured to determine a first difference between the first sensed LeadZ and the second sensed LeadZ, and determine a parameter based at least in part on the first difference. The first sensed LeadZ and the second sensed LeadZ are sensed during a same first cardiac cycle or adjacent cardiac cycles of a heart that is receiving pacing.

Abstract: Systems and methods are described herein for use in synchronizing electrical activity monitored by a plurality of external electrodes with supplemental cardiac data for use in evaluating a patient's cardiac condition and configuring cardiac therapy. The supplemental cardiac data may include one or more markers indicative of the occurrence of cardiac events and/or data representative of representative of at least one of cardiac electrical signals, cardiac sounds, cardiac pressures, blood flow, and an estimated instantaneous flow waveform provided by a left ventricular assist device.

Abstract: The present disclosure is directed to a shuttle apparatus for detachably joining a catheter to a guidewire so that the joined catheter, extending alongside the guidewire, is in sliding engagement with the guidewire without extending around the guidewire. The apparatus comprises a collar member sized for mounting in sliding engagement around a length of the guidewire, the collar member having a longitudinal axis that approximately aligns along the length, when mounted thereabout, the length being defined between a proximal-most point of the guidewire and a distal point of the guidewire, the distal point being offset proximally from a distal-most point of the guidewire. The apparatus further comprises a plug member coupled to the collar member, the plug member having a longitudinal axis, and the plug member being sized to fit within an opening of the catheter for detachable engagement therewith.

Abstract: This disclosure provides tools and implant techniques utilizing such tools to gain access to and implant a medical device, such as a medical electrical lead, within extravascular spaces. In one example, this disclosure provides a tool for creating a sub-sternal tunnel in a patient. The tool comprises a relatively straight guide member extending from a first end thereof to a second end thereof, a tunneling member extending from a first end thereof to a tip thereof, the tunneling member extending alongside and coplanar with the guide member, the first end of the tunneling member and the first end of the guide member being joined together, and a handle coupled to the guide member.

Abstract: An apparatus for forming a passageway through tissue includes a dilator mounted to a shaft, wherein the dilator includes a first portion, which has an increasing taper from a first outer diameter to a larger second outer diameter, and a second portion, which has a decreasing taper from the first portion to a distal end of the dilator, and which includes an external non-cutting thread formed along the decreasing taper. Lumens of the dilator and shaft provide a conduit for means to pierce through the tissue, for example, an elongate wire that includes a piercing tip. In some cases, the dilator first portion is expandable to, and contractible from, the larger second outer diameter, wherein the apparatus may include a spreading member configured to slide between the shaft and the first portion. The apparatus may be included in a system with an introducer sheath.

Abstract: Techniques are disclosed for detecting when a patient is experiencing seasonal affective disorder (SAD). An example computer-implemented method includes determining a status of one or more health metrics for a patient based on sensor data collected from at least one biometric device. The method also includes determining potential sun exposure for a patient based on weather metrics corresponding in time with the health metrics. Additionally, the method includes, when a decline in the status of the health metrics for the patient correlates with declining potential sun exposure, providing an alert indicative that patient is experiencing SAD.
