Abstract: Provided are metal oxide varistors comprising a sintered ceramic, in which the ceramic comprises, by weight, about 91.0% to about 97.0% ZnO, at least 0.3% Mn, at least 0.4% Bi, at least 1.0% Sb, and 0.50% or less Co. The metal oxide varistors as disclosed herein may exhibit reduced power dissipation, improved thermal stability, and may be produced at a lower cost relative to conventional MOV devices.

Abstract: The invention relates generally to methods and systems for irrigating particulates during heart pump implantation, and more specifically relates to irrigating and removing particulates that may be released when coring a patient's heart tissue. A method of irrigating particulates during blood pump implantation includes inserting a removable tissue irrigating device into a patient's heart. The removable tissue irrigating device includes a delivery tube and an irrigation conduit extending through the delivery tube. The irrigation conduit is extended out of an opening in the delivery tube to a deployed position from a stored position. The irrigation conduit is substantially disposed within the delivery tube when in the stored position and has a distal portion protruding out of the delivery tube when in the deployed position. Fluid is dispersed from the irrigation conduit into the patient's heart to remove particulates released during and/or after a coring procedure.

Abstract: The invention relates generally to methods and systems for irrigating or capturing particulates during heart pump implantation, and more specifically relates to irrigating, capturing, and removing particulates that may be released when coring a patient's heart tissue. In one aspect, a method for capturing particulates during heart pump implantation is provided that includes inserting a removable particulate capture device into a patient's heart prior to a coring procedure upon the patient's heart. The removable particulate capture device includes an expandable basket movable between collapsed and expanded configurations. The method further includes expanding the expandable basket to the expanded configuration from the collapsed configuration when the removable particulate capture device is positioned within the patient's heart to capture the particulates released during the coring procedure.
