Abstract: A system comprises a memory, a plurality of electrodes, sensing circuitry, and processing circuitry. The sensing circuitry configured to determine one or more tissue impedance values via the electrodes, wherein the tissue impedance values vary as a function of ejection fraction of a heart of a patient. The processing circuitry configured to determine, at least based on the one or more tissue impedance values, a stroke metric indicative of a stroke status of the patient, and store the stroke metric in a memory.

Abstract: A system comprises a sensor device and processing circuitry. The sensor device comprises a housing configured to be disposed above shoulders of a patient, a plurality of electrodes on the housing, a motion sensor, and sensing circuitry configured to sense a brain electrical signal and a cardiac electrical signal via the electrodes, and a motion signal via the motion sensor. The processing circuitry is configured to determine values over time of one or more parameters from the brain electrical signal, determine values over time of one or more parameters from the cardiac electrical signal, and generate at least one of a detection, prediction, or a classification a condition of the patient based on the values and the motion signal.

Abstract: Methods for forming an expandable tubular body having a plurality of braided filaments including a first filament including platinum or platinum alloy and a second filament including cobalt-chromium alloy. The methods include applying a first phosphorylcholine material directly on the platinum or platinum alloy of the first filament and applying a silane material on the second filament followed by a second phosphorylcholine material on the silane material on the second filament. The first and second phosphorylcholine materials each define a thickness of less than 100 nanometers.

Abstract: Coating methods and related devices are provided. Such devices can include stents. For example, the device can comprise a sidewall and a plurality of pores in the sidewall that are sized to inhibit flow of blood through the sidewall into an aneurysm to a degree sufficient to lead to thrombosis and healing of the aneurysm when the tubular member is positioned in a blood vessel and adjacent to the aneurysm. The device can also comprise an anti-thrombogenic coating distributed over at least a portion of the device such that the pores are substantially free of webs formed by the coating.

Abstract: Retrieval of material from vessel lumens can be improved by use of a distal element comprising an expandable mesh. a treatment device includes an elongated member having a proximal portion and a distal portion configured to be positioned within a blood vessel at a treatment site at or near a thrombus. A distal element comprising a plurality of woven filaments defining a shaft at a proximal portion and a body distal of the shaft is coupled to the distal portion of the elongated member via a connection assembly. In an expanded state, at least a portion of the distal element is configured to be in apposition with the blood vessel wall at the treatment site to anchor or stabilize the elongated member with respect to the blood vessel. The distal element can be electrically coupled to an extracorporeal current generator.

Abstract: A method for treating an aneurysm in accordance with a particular embodiment of the present technology includes intravascularly delivering a mixture including a biopolymer (e.g., chitosan) and a chemical crosslinking agent (e.g., genipin) to an aneurysm. The method further includes mixing the biopolymer and the chemical crosslinking agent to initiate chemical crosslinking of the biopolymer. The mixture is delivered to the aneurysm via a lumen and an exit port of a catheter while the chemical crosslinking is ongoing. The mixture exits the catheter as a single cohesive strand that at least partially agglomerates to form a mass occupying at least 75% of a total internal volume of the aneurysm. During delivery of the mixture, the method includes expanding a tubular flow diverter to reinforce a neck of the aneurysm.

Abstract: Expandable devices are disclosed herein. Several of the embodiments are directed towards an expandable device comprising a mesh configured to be expanded at a blood vessel bifurcation of a human patient. The mesh may comprise a tubular body portion and one or more circumferentially discontinuous articulating portions. The mesh may be expanded such that the one or more articulating portions are positioned at an angle to the tubular body portion.
