Publication number: 20230241371Abstract: An implantable pump system is provided, including an implantable blood pump suitable for use as a partial support assist device, the system further including an extracorporeal battery and a controller coupled to the implantable pump, and a programmer selectively periodically coupled to the controller to configure and adjust operating parameters of the implantable pump. The implantable pump includes a flexible membrane coupled to an electromagnetic actuator including a magnetic assembly and electromagnetic assembly, so that when the electromagnetic assembly is energized, the electromagnetic assembly causes wavelike undulations to propagate along the flexible membrane to propel blood through the implantable pump. The controller may be programmed by a programmer to operate at frequencies and duty cycles that mimic physiologic flow rates and pulsatility while operating in an efficient manner that avoids thrombus formation, hemolysis and/or platelet activation.Type: ApplicationFiled: April 6, 2023Publication date: August 3, 2023Applicant: CorWave SAInventors: Louis-Emmanuel LE DUC DE LILLERS, Francois CORNAT, Jean-Baptiste DREVET, Carl N.

Publication number: 20230001179Abstract: An implantable pump system is provided, suitable for use as a left ventricular assist device (LVAD) system, having an implantable pump, a battery, a controller, and a programmer. The implantable pump includes a flexible membrane coupled to an actuator assembly via a skirt that extends toward the inlet of the pump and curves to guide blood toward the outlet. The actuator assembly is magnetically engageable with electromagnetic coils, so that when the electromagnetic coils are energized, the actuator assembly causes wavelike undulations to propagate along the flexible membrane to propel blood from the inlet, across the skirt, and through the outlet of the implantable pump. The controller may be programmed by a programmer to operate at frequencies and duty cycles that mimic physiologic flow rates and pulsatility while operating in an efficient manner that avoids thrombus formation, hemolysis and/or platelet activation.Type: ApplicationFiled: September 7, 2022Publication date: January 5, 2023Applicant: CorWave SAInventors: Luc POLVERELLI, Leopold MAINE, Carl N.

Patent number: 7650301Abstract: To ensure merchant acquisition compliance, the invention enables creation of merchant selection criteria that are used to query a database of acquired merchants. A set of acquired merchants is randomly compiled based on the selection criteria and is entered into a workflow to determine compliance with a set of rules that are represented by a checklist. A checklist corresponding to the set of acquired merchants is retrieved. The set and the checklist are combined to create a case, which is assigned to a representative. The representative ensures that a merchant acquisition form for each merchant in the set complies with a checklist item. When a merchant acquisition form is found to be non-compliant, then it is either corrected by the representative (if the error is minor), or sent to an acquisition manager (when more substantive errors are found). The acquisition form is then corrected and the case is closed.Type: GrantFiled: September 5, 2007Date of Patent: January 19, 2010Assignee: American Express Travel Related Services Company, Inc.Inventors: Burges Bharucha, Julie Bowers, Jeffrey John Newton, Alexandra Schmidt, Ram Chandran Viswanathan, Riththidej Vuwong

Patent number: 6663156Abstract: A protective mat assembly for preventing undesirable contact between a person and an exterior surface of a vehicle when accessing the vehicle's cargo area as well as protecting the interior cargo space when carrying dirty objects. A folding mat is conveniently stowed in and deployed from its own storage compartment housed in the vehicle's cargo area. The mat can be easily moved between three positions, depending upon the intended use of the vehicle cargo area. In a fully stowed position, the mat is housed substantially within the storage compartment and is out of the way, enabling use of the vehicle cargo area by passengers or to carry relatively clean and large items such as luggage. In a first operative position, the mat is deployed from its storage compartment and extends out through a vehicle opening, draping over the opening as well as adjacent exterior surfaces of the vehicle such as a bumper or sill.Type: GrantFiled: February 28, 2003Date of Patent: December 16, 2003Assignee: Ford Motor CorporationInventors: Mason C. Kincaid, Alexandra Schmidt, Brian Ehrlich, G. Sean Haag, Susan Eitelman, Yonah Graves
