20090210186 | Operating Method for a Sensor and a Control Facility Communicating With the Sensor - A sensor has a detection device and an evaluation device to detect an analog signal, to determine a digital signal and to transmit the digital signal to a control device outside the sensor. The analog signal and/or the digital signal is supplied to a monitoring device of the sensor. An enable signal is transmitted to the control device only if the device being monitored is operating correctly. In a normal mode, the control device processes the digital signal further. Otherwise, it deems the transmitted digital signal to be defective and outputs a message using a malfunction of the sensor. On account of the transmission of the test signal, the sensor assumes a test mode in which it manipulates the signals which are supplied to the monitoring device in such that the monitoring device detects that the device being monitored is not operating correctly. In the test mode, the control device outputs a message using a malfunction of the sensor if the enable signal is transmitted to it in addition to each. | 08-20-2009 |

20090024212 | A METHOD FOR PERFORMING INTRAVASCULAR CARDIAC SURGERY - For the treatment of an insufficient cardiac valve or a cardiac valve with a stenosis, a device is provided that comprises a micro axial pump ( | 01-22-2009 |
20090138080 | Method for Controlling a Blood Pump - A blood pump is temporarily operated at a low rotational speed lying below a design rotational speed. This involves a risk of thrombogenesis since flow detachments may occur at blades of an impeller of the rotary blood pump. For eliminating deposits at said impeller, the rotational speed of said pump is temporarily increased to the design rotational speed. Alternatively, said pump alternately operates at said design rotational speed and a low rotational speed, and this pulsed operation is synchronized with the heart rate. | 05-28-2009 |

20140364768 | LOADING GUIDE LUMEN - An apparatus is disclosed including: an intracardiac pump device having a path for a guidewire extending through the pump device from a first opening to a second opening; and a lumen which extends from a first end located outside of the pump device, into the pump device through the first opening in the pump device, along the path for the guidewire, out of the pump device through the second opening, and to a second end located outside of the pump device. The lumen is configured to receive the guidewire such that when the guidewire passes through the lumen from the first end to the second end, the guidewire is positioned along the path. | 12-11-2014 |
