The stationary carrier holds at least a stationary transmitter coupler of a contactless data link, such as a strip line. The stationary carrier is made of sheet metal or plastic material, and therefore can easily be prepared on a plane work bench before it is bent to a ring shape. | 2019-12-12 |

20190374195 | SINGLE CATHETER SYSTEM THAT PROVIDES BOTH INTRAVASCULAR ULTRASOUND AND FLUORESCENCE LIFETIME IMAGING - A multimodal intravascular catheter system includes a catheter with an optical channel and an electrical channel. A distal end of the catheter includes an optical element and an ultrasonic transducer, which are oriented orthogonally to a rotational axis of the catheter. A motor drive unit (MDU) is coupled to a proximal end of the catheter and includes a drive motor to rotate the catheter. The optical channel directs light from a pulsed UV laser source to the optical element, and returns an optical fluorescence signal from the optical element. A photodetector converts the returned optical fluorescence signal into an electrical fluorescence signal. An intravascular ultrasound (IVUS) processor is coupled to the ultrasonic transducer through the electrical channel, wherein the IVUS processor generates a drive signal for the ultrasound transducer, and processes echo information returned from the ultrasound transducer. Finally, a digitizer samples the electrical fluorescence signal and associated echo information. | 2019-12-12 |
20190374196 | IMAGING PROBE WITH ROTATABLE CORE - The present disclosure provides for an imaging probe with a rotatable core which allows for rotating imaging assembly that is larger in diameter than the lumen in which the rotatable core resides, as well as methods to construct said probes. The imaging probes are generally elongate flexible imaging catheters for use in cardiovascular procedures. The ability to have a smaller lumen to hold the rotatable core simplifies the inclusion of other functional components to the catheter and may improve the quality of the images produced. | 2019-12-12 |
