Patent number: 9893522Abstract: A parallel filter arrangement with at least two filters supplying current in line side sensing configuration and a number of sensors for measuring current. The sensors are used to determine the amount of current being supplied by the filters and the amount of current being supplied by a source. The filters adjust their supplied current in order to reduce or eliminate the amount of reactive or harmonic current being supplied by a source.Type: GrantFiled: July 24, 2015Date of Patent: February 13, 2018Assignee: TCI, LLCInventors: Ian Wallace, Ashish Bendre, William Kranz, Jeff Seibold

Patent number: 9786150Abstract: A method for outputting a combined power source alarm for an implantable blood pump includes determining a status for each of first and second power sources of the blood pump. A combined power source alarm based on the statuses of the first and second power sources is outputted. A method for generating an alarm based on fault detections in a mechanically assisted circulation system includes processing a series of fault detection indications to classify a fault as active or inactive. An alarm is generated if the fault is active for more than a predetermined amount of time.Type: GrantFiled: April 15, 2015Date of Patent: October 10, 2017Assignee: TCI LLCInventors: Brian Kimball, Charles Dague, W. Kevin Wu

Patent number: 9757502Abstract: In one general aspect, a method includes measuring blood flow through a right rotary blood pump, measuring blood flow through a left rotary blood pump, and controlling a speed of one of the rotary blood pumps using a controller that calculates the speed of one of the rotary blood pumps based on the measured blood flow through the other rotary blood pump.Type: GrantFiled: September 23, 2011Date of Patent: September 12, 2017Assignee: TCI LLCInventors: David J. Burke, Kevin Bourque

Patent number: 9687596Abstract: Materials and methods related to blood pump systems are described. These can be used in patients to, for example, monitor arterial pressure, measure blood flow, maintain left ventricular pressure within a particular range, avoid left ventricular collapse, prevent fusion of the aortic valve in a subject having a blood pump, and provide a means to wean a patient from a blood pump.Type: GrantFiled: September 10, 2013Date of Patent: June 27, 2017Assignee: TCI LLCInventor: Victor Poirier

Patent number: 9603984Abstract: A power cable having improved durability and associated methods of assembly and use are described herein. In one aspect, the power cable is adapted for use in powering an implantable circulatory pump system. The cable includes one or more conductors of uninsulated wire strands that are loosely packed so as to move relative one another during cable flexure. The driveline cable may include a plurality of conductors, each comprised of multiple uninsulated bundles of uninsulated, loosely packed wire strands of a conductive material, that are wrapped about a central core. The cable may include at least six conductors, each conductor having at least 200 wire strands of a 30 gauge or higher. The cable may include the plurality of wire strands wound in a Litz style configuration to provide improved durability over many cycles of use at reduced cost, improved integrity of the electrical connection and reduced diameter.Type: GrantFiled: September 3, 2015Date of Patent: March 28, 2017Assignee: TCI LLCInventors: Jaime Romero, Nathan Harold

Patent number: 9257894Abstract: A passive filter for connection between an AC source and a load, in either three-phases or in a single-phase arrangement. The filter includes, for each phase, a trap circuit having an inductor in series with a capacitor, the trap circuit having at least two terminals. A line reactor is connected between the AC source and the load, the line reactor having at least an input terminal, an output terminal and a tap terminal. A switch selectively connects at least one of the trap circuit terminals to a selected one of the line reactor terminals. The switch is capable of selecting which of the trap circuit terminals to connect to which of the line reactor terminals on the basis of a level of voltage distortion being experienced by the AC source, or on the basis of a calculated level of background voltage total harmonic distortion.Type: GrantFiled: September 30, 2014Date of Patent: February 9, 2016Assignee: TCI, LLCInventors: Ian Wallace, Ashish Bendre, Neil Wood, William Kranz
