Patent number: 9295767Abstract: A heart assistance device for the pulsatile delivery of blood is provided that includes a first pump chamber, a second pump chamber, and a pump. Both pump chambers each have a fluid chamber and a blood-carrying chamber. By means of the pump, each fluid chamber can be filled with a fluid or emptied thereof in such a way that an expansion or contraction of the fluid chamber takes place. During the expansion of the fluid chamber of one pump chamber, a compression of the blood-carrying chamber of the same blood chamber takes place. The pump is designed as a roller cell pump or vane pump.Type: GrantFiled: April 21, 2011Date of Patent: March 29, 2016Assignee: DEUTSCHES ZENTRUM FUER LUFT-UND RAUMFAHRT E.V.Inventors: Thomas Schmid, Bernhard Vodermayer, Heinrich Gmeiner, Alexandra Wimmer, Andreas Kunz, Wolfgang Schiller

Patent number: 9283309Abstract: A device for supplying energy to hydraulically or pneumatically actuated active implants. The device can take the form of pumping systems, metering systems, and/or occlusion systems. The device comprises a receiving coil for generating an electric voltage due to a changing magnetic flux that is generated by an extracorporeal transmitting coil. The receiving coil is designed such that said coil can be implanted into subcutaneous tissue. Furthermore, an electric line is provided for transmitting the electric current that is generated by the receiving coil from the receiving coil to the active implant. The device further comprises a compensation container for temporarily receiving a transmitter fluid, by means of which the active implant is activated. The compensating container is mounted on the receiving coil and/or on the electric line such that the compensating container together with the receiving coil and/or the electric line can be implanted into a common tissue or muscle pocket in the body of a patient.Type: GrantFiled: March 18, 2011Date of Patent: March 15, 2016Assignee: Deutsches Zentrum Fuer Luft-Und Raumfahrt E.V.Inventors: Thomas Schmid, Bernhard Vodermayer, Cornelia Riecke, Annika Rybak, Matthias Grzeski

Patent number: 8834343Abstract: A heart support device for pulsatile delivery of blood comprising a first and a second ventricle and a pump. Both ventricles comprises a fluid chamber and a blood-conveying chamber, wherein each fluid chamber can be filled with a fluid or emptied by way of the pump in such a way that an expansion or contraction of the fluid chamber occurs. In an expansion of the fluid chamber of a ventricle, a compression of the blood-conveying chamber of the same ventricle takes place, wherein a rigid pressure plate is disposed between a fluid chamber and the respective blood-conveying chamber, said pressure plate being able to move in the direction of the respective blood-conveying chamber.Type: GrantFiled: April 3, 2009Date of Patent: September 16, 2014Assignee: Deutsches Zentrum Fur Luft-UndInventors: Bernhard Vodermayer, Harald Wagner, Wolfgang Schiller, Thomas Schmid

Patent number: 8398536Abstract: An implantable two-chamber system is for supporting the left ventricle of the heart. Each of the two pumping chambers (1, 1?) of the two-chamber system is ventricular shaped including an inlet (11) and an outlet (12). A pressure plate (2) is rotatably mounted externally in two arms (5) which are movably retained on the output shaft (9) of a drive unit (15) such that the center of motion (8) of the arms (5), which lies on the output shaft (9), is located on the side of the pumping chamber (1, 1?) facing away from adapters (4, 4?), and thus outside the pumping chambers (1, 1?). Each of the ventricular pumping chambers (1, 1?) is provided with a bulge (13) in order to reduce the resistance to fluid flow, this bulge (13) having a length ranging from 10 to 15 percent of the length of the pumping chamber.Type: GrantFiled: July 17, 2007Date of Patent: March 19, 2013Assignee: Deutsches Zentrum fuer Luft- und Raumfahrt e.V.Inventors: Bernhard Vodermayer, Thomas Schmid

Publication number: 20090240097Abstract: Disclosed is an implantable two-chamber system for supporting the left ventricle of the heart. Each of the two pumping chambers (1, 1?) of the two-chamber system has the shape of a ventricular bag comprising an inlet (11) that is embodied at one end at an acute angle (a) to an outlet (12), directly next the outlet (12). Furthermore, a pressure plate (2) is rotatably mounted externally in two arms (5) which are movably retained on the output shaft (9) of a drive unit (15) such that the center of motion (8) of the arms (5), which lies on the output shaft (9), is located on the side of the pumping chambers (, 1?) facing away from adapters (4, 4?), and thus outside the pumping chambers (1, 1?). The angle between the inlet (11) and the outlet (12) of each pumping chamber ranges from 30° to 60°. The maximum width in the inlet and outlet zone of each of the pumping chambers (1, 1?) amounts to about 65 to 72 percent of the length of the respective pumping chamber.Type: ApplicationFiled: July 17, 2007Publication date: September 24, 2009Applicant: DEUTSCHES ZENTRUM FUER LUFT-UND RAUMFAHRT E.V.Inventors: Bernhard Vodermayer, Thomas Schmid
