Patent number: 11504529Abstract: An intraseptal multi-electrode cardiac pacemaker has a plurality of first individual electrodes implanted at an interventricular septum at varying depths and/or lateral distances from the distal end of a flexible conduit and configured to provide a cardiac pacing therapy by stimulating left bundle branch conduction fibers. A plurality of second individual electrodes may also be implanted in the septum at suitable depths to stimulate conduction fibers of the right bundle branch. After implantation, first and second individual electrodes are interrogated to select a subset of electrodes suitable to deliver the pacing therapy according to a predetermined criterion such as capturing the left ventricle or capturing the right ventricle via normal conduction system of the heart at the lowest voltage level via corresponding bundle branches. A combination of the pacemaker with a cardioverter/defibrillator is provided by positioning a defibrillator coil near the distal end of the flexible conduit of the pacemaker.Type: GrantFiled: July 3, 2020Date of Patent: November 22, 2022Assignee: Eagle Point Medical LLCInventors: Leonid Makharinsky, Daniel Lev Makharinsky

Patent number: 11045653Abstract: A method for pacing left bundle branch of the heart comprising implantation of a multi-electrode lead at a desired depth into the interventricular septum from the right ventricle, wherein the depth control during the implantation of the distal electrode is provided by monitoring electrical impedance for one or more intermediate electrodes. Reaching of exceeding a threshold of electrical impedance change is used to determine the entry of a corresponding intermediate electrode from the blood stream in the right ventricle into the cardiac tissue of the septum. Known distances between intermediate spaced apart electrodes and the distal electrode allow determination of the implantation depth of the distal electrode.Type: GrantFiled: February 11, 2021Date of Patent: June 29, 2021Assignee: Eagle Point Medical LLCInventors: Leonid Makharinsky, Daniel Lev Makharinsky, Andrei Leonidovich Starostin

Publication number: 20070031321Abstract: A process, composition and apparatus for the removal of impurities from corrosive gases, particularly halogen-containing gases, down to about 100 ppb concentration are described. The critical component is zirconia (ZrO2), which in a variety of physical forms is capable of dehydrating such gases. The zirconia can be in the form of a coating on a substrate, as a granular bulk material, or deposited within the pores of a porous body. The zirconia is retained in a simple container which is easily installed in a gas supply line, such as to a gas- or vapor-deposition manufacturing unit. The purification process can be operated for long periods of time in the presence of these gases. The invention provides final purification to gas streams intended for gas- or vapor-deposition formation of high purity electronic, prosthetic or similar products, and can be used in combination with a preliminary dehydration process or a solid particulate removal unit upstream.Type: ApplicationFiled: June 23, 2004Publication date: February 8, 2007Inventors: Daniel Alvarez, Daniel Lev, Jeffrey Spiegelman, Tram Nguyen, Russell Holmes

Publication number: 20040076575Abstract: A method for decontaminating fluid carbon dioxide for use in a product production process such as carbonated beverage production is disclosed. Contaminants, including those normally highly resistant to removal such as S, N, P and Si compounds (especially COS), are removed from the CO2 by contact with a metal oxide decontamination agent. The metal oxide is one or more oxides of transition metal elements including lanthanides, the iron oxides being preferred. Decontamination of the CO2 is interrupted at intervals for regeneration of the metal oxide agent by passage of CO2 containing an oxygen-containing contaminant over the metal oxide in a countercurrent flow direction at higher temperature for a short time. The metal oxide decontaminant may also be mixed with a high-silica content zeolite, preferably a Zeolite Y or zeolite ZSM-5. The contaminated CO2 and the CO2 containing an oxygen-containing contaminant are preferably from the same source.Type: ApplicationFiled: October 17, 2002Publication date: April 22, 2004Inventors: Daniel Alvarez, Jeffrey J.
