20090048524 | IMPLANTABLE PRESSURE MEASURING UNIT AND CONFIGURATION FOR INTERNAL PRESSURE MEASUREMENT IN A BLOOD VESSEL - Implantable pressure measuring unit for internal pressure measurement in a blood vessel or heart of a patient, having a pressure sensor having electrical signal output, fixing means adapted to the intended measurement location for fixing the pressure sensor, a power supply unit of the pressure sensor, a signal detection unit connected by a line to the signal output of the pressure sensor, and a transmitting unit connected to a measurement data output of the signal detection unit, in particular for wireless transmission of measurement data to an analysis unit, in particular outward from the patient body. | 02-19-2009 |
20090088609 | Method of taking internal physiological measurements - The invention relates to a device for detecting physiological measured variables within the body, comprising a catheter which has a tip supporting a sensor and which can be introduced into a blood vessel, the catheter ( | 04-02-2009 |
20090093764 | CATHETER DEVICE - The catheter device comprises a motor located at the proximal end of the catheter device and a drive shaft, extending from the proximal end section to the distal end section of the catheter device, for driving a rotating element located at the distal end of the catheter device. The catheter device also comprises a hose-like catheter body which encompasses the drive shaft and extends from the proximal end section to the distal end section of the catheter device. At the proximal end of the catheter device, the drive shaft is connected to a motor by a clutch. The clutch is a magnetic clutch with a proximal and a distal magnet unit. The proximal magnet unit is connected to the motor and the distal magnet unit to the drive shaft. The distal magnet unit is mounted fluid-tight in a clutch housing. The proximal end of the catheter body makes a fluid-tight connection with the clutch housing. | 04-09-2009 |
20090093796 | CATHETER DEVICE - The catheter device comprises a drive shaft connected to a motor, and a rotor mounted on the drive shaft at the distal end section. The rotor has a frame structure which is formed by a screw-like boundary frame and rotor struts extending radially inwards from the boundary frame. The rotor struts are fastened to the drive shaft by their ends opposite the boundary frame. Between the boundary frame and the drive shaft extends an elastic covering. The frame structure is made of an elastic material such that, after forced compression, the rotor unfolds automatically. | 04-09-2009 |

20140061116 | EXCHANGER DEVICE - An exchanger device for transferring mass and/or energy between a first medium and a second medium includes a chamber having a first inlet and first outlet of the first medium and through which the first medium can flow. The chamber is equipped with at least one, preferably a plurality, of one mass- and/or energy-permeable exchanger hollow fibers connected at one end to a second inlet and at the other end to a second outlet of the second medium. The second medium can flow through the fiber(s) and the first medium can flow around the fiber(s). The chamber is equipped with at least one pump element for displacing the first medium in and out of the chamber in a pulsing manner. The pump element has an elastically deformable element, is connected to a third inlet of a third medium used as a driving medium, and is expandable by the third medium. | 03-06-2014 |
