Publication number: 20240075276Abstract: A cardiac assist device with an expandable cup (4) having a transport state and an operational state, the expandable cup comprising a plurality of inflow apertures (5), and an outflow nozzle (6), and an inflatable balloon (8) positioned inside the expandable cup (4). A catheter assembly (3) is connected to the inflatable balloon (8) during operation, and a control unit (2) is connected to the catheter assembly (3). The control unit (2) is arranged to operate the inflatable balloon (8) with a frequency of more than 100 beats per minute.Type: ApplicationFiled: November 2, 2023Publication date: March 7, 2024Inventors: Daniël Immanuel Michaël van Dort, René Cornelis Henricus van der Burgt, Florian Niklas Ludwig

Publication number: 20230248961Abstract: A cardiac assist device (1) with a cup element (2), an inner balloon element (5) and a tube element (6). The cup element (2) has a cup wall (2a), one or more in-flow openings (3), and an outflow element (4 having an aperture (4a). The inner balloon element (5) is positioned inside the cup element (2) free from the outflow element (4). The tube element (6) is arranged for inflating and deflating the inner balloon element (5) during operation. During operation in a pumping operational mode, the combination of first material, dimensions of the cup wall (2a), and dimensions of the outflow element (4) provides a containment force by the cup element (2) counteracting an outward directed force of the inner balloon element (5).Type: ApplicationFiled: April 13, 2023Publication date: August 10, 2023Inventors: Daniël Immanuel Michaël van Dort, Florian Niklas Ludwig

Publication number: 20220347460Abstract: A heart support device for circulatory assistance is disclosed. The device comprises a chamber body defining a chamber having an internal volume configured to be filled with blood. The chamber body has a first opening and the chamber is dimensioned such that the first opening and the chamber are fully disposed within a chamber of the human heart. A dynamic volume body is provided and configured to be inflated or deflated to alternately increase or decrease the interior volume of the chamber. A catheter comprising at least one lumen in fluid communication with the dynamic volume body is configured to deliver fluid to the dynamic volume body to inflate the dynamic volume body. A directional flow structure is configured to direct a flow of blood out of the chamber in a direction substantially aligned with a direction in which the catheter extends.Type: ApplicationFiled: July 19, 2022Publication date: November 3, 2022Inventor: Daniël Immanuel Michaël van Dort

Patent number: 11400274Abstract: A heart support device for circulatory assistance is disclosed. The device comprises a chamber body (10) defining a chamber having an internal volume configured to be filled with blood. The chamber body (10) has a first opening (12) and the chamber is dimensioned such that the first opening (12) and the chamber are fully disposed within a chamber of the human heart. A dynamic volume body (14) is provided and configured to be inflated or deflated to alternately increase or decrease the interior volume of the chamber. A catheter (16) comprising at least one lumen in fluid communication with the dynamic volume body is configured to deliver fluid to the dynamic volume body to inflate the dynamic volume body. A directional flow structure is configured to direct a flow of blood out of the chamber in a direction substantially aligned with a direction in which the catheter (16) extends.Type: GrantFiled: July 26, 2019Date of Patent: August 2, 2022Assignee: Stichting Katholieke UniversiteitInventor: Daniel Immanuel Michaël van Dort

Publication number: 20220161017Abstract: A device (2) for providing circulatory assistance is provided and comprises a balloon (4) comprising a membrane defining a cavity having an internal volume (Vc), wherein the balloon comprises a proximal portion (4a) comprising a proximal end and a distal portion (4b) comprising a distal end. The device (2) further comprises a first catheter, affixed to the distal end of the balloon (4) at a first fixation point (P1) and a second catheter (8), affixed to the proximal end of the balloon at a second fixation point (P2). The second catheter (8) is configured for axial movement with respect to the first catheter or guide wire (6) between a first position in which the first and second fixation points (P1, P2) are spaced apart from each other in the longitudinal direction by a first distance (Dx), which is variable to bring about inversion of the balloon.Type: ApplicationFiled: February 28, 2020Publication date: May 26, 2022Applicant: Stichting Radboud universitair medisch centrumInventor: Daniël Immanuel Michaël van Dort

Publication number: 20220134081Abstract: A heart support device for circulatory assistance is disclosed. The device (2) comprises a chamber body (4) comprising an outer wall and defining an internal volume (Vx) configured to receive a volume of fluid. The chamber body (4) comprises an outlet opening (8) at its proximal end (4a), the outlet opening (8) being in fluid communication with an exterior volume in which the chamber body (4) is disposed. The outer wall of the chamber body (4) is configured to alternately collapse and expand between a first configuration in which the internal volume Vx=V1 and a second configuration in which the internal volume Vx=V2, wherein Vi is larger than V2, and thereby pump the fluid through the outlet opening (8). The cross-sectional internal diameter of the outlet opening (8) is less than a maximum cross-sectional internal diameter of the chamber body (4).Type: ApplicationFiled: February 28, 2020Publication date: May 5, 2022Applicant: CardiacBooster B.V.Inventors: Daniël Immanuel Michaël van Dort, Florian Niklas Ludwig, Bob Petrus Hermans, Koen Ronaldus Antonius Hermanus Peij, Jos Thannhauser
