Abstract: Devices, systems and methods are described herein to provide improved steerability for delivering a prosthesis to a body location, for example, for delivering a replacement mitral valve to a native mitral valve location. The delivery system can include a number of advantageous steering and delivery features, in particular for the transseptal delivery approach.

Abstract: A catheter for debulking of an undesired deposit from an inner surface of at least one of a blood vessel wall and a stent located in a blood vessel, the catheter having a tip section comprising: circumferentially-directed laser optics; and a circular-action cutter, wherein said circumferentially-directed laser optics is configured to transmit laser radiation for modifying an area of the undesired deposit thereby preparing said area for penetration of said cutter, wherein said cutter is configured to cut through said modified area and thereby debulk at least a part of the undesired deposit. In addition, a catheter for pacemaker and ICD (Implantable Cardioverter Defibrillator) lead extraction is disclosed.

Abstract: Systems and methods are provided for a three-phase compensation system, whereby an electric circuit is configured to be connected with three input phases of a power source and to supply three respective output phases, said electric circuit further configured to compensate for one or two malfunctioning input phases of said three input phases by supplying current from a functioning input phase of said three input phases to replace a malfunctioning input phase.

Abstract: A protection circuit provides a control voltage to a 3-phase contactor, where the three phases of the 3-phase power supply are inputs to the 3-phase contactor. The protection circuit includes: four input terminals, configured to be connected respectively to the three phases and to the neutral line of the 3-phase power supply; an output terminal, providing the control voltage to a control line of the 3-phase contactor; and control circuitry configured to provide the control voltage when any one or more of the three phases are live and when the neutral line is connected, and to provide no control voltage when all three phases are disconnected or when the neutral line is disconnected.

Abstract: Systems and methods are provided for detecting and compensating for loss of a phase of a three-phase power source, elements of the system including: a sensing unit, which measures current and voltage levels of each phase of the three-phase power source; a switching unit having three primary relays and three backup relays; and a microcontroller, configured to receive measurements from the sensing unit, to determine from the measurements a lost phase and a less-loaded phase of the two remaining phases, and responsively to activate the switching unit to disconnect the lost phase and to connect the less loaded phase to provide backup power in place of the lost phase.
