摘要： A monitoring device configured to be attached to the ear of a person includes a base, an earbud housing extending outwardly from the base that is configured to be positioned within an ear of a subject, and a cover surrounding the earbud housing. The base includes a speaker, an optical emitter, and an optical detector. The cover includes light transmissive material that is in optical communication with the optical emitter and the optical detector and serves as a light guide to deliver light from the optical emitter into the ear canal of the subject wearing the device at one or more predetermined locations and to collect light external to the earbud housing and deliver the collected light to the optical detector.

摘要： Systems and methods for epicardial electrophysiology and other procedures are provided in which conditions at the location of an access needle may be determined according to the detection of different pressure frequencies in separate organs, or different locations, in the body of a subject. Methods may include inserting a needle including a first sensor into a body of a subject, and receiving pressure frequency information from the first sensor. A second sensor may be used to provide cardiac waveform information of the subject, and the pressure frequency information may be segmented based on the cardiac waveform information. Conditions at the current location of the needle may be determined based on an algorithm including the segmented pressure frequency information and the cardiac waveform information.

摘要： The present invention relates to a perfusion cannula for placement of an access, having a cannula wall and a perfusion lumen which is surrounded by the cannula wall and in which a fluid flow can flow through the perfusion cannula, wherein the perfusion cannula furthermore comprises at least one sensor lumen and at least one sensor device, in particular an ECG sensor, which is arranged at least partially in the sensor lumen. As a result, it is possible to provide a particularly reliable perfusion cannula with improved functionality and for reliable handling, in particular in conjunction with an extracorporeal lung support system.

摘要： A catheter (20), which can be part of an intravascular blood pump, possesses a kink sensor which extends over the total length of the catheter and comprises an optical fiber (28A). The optical fiber is attached to an evaluation device (100) which evaluates a preset light quantity transmitted through the optical fiber as to whether a part of the light quantity is coupled out of the optical fiber along the length of the optical fiber. This is interpreted as a kink event and displayed. The optical fiber preferably utilized for the kink sensor is the optical fiber of an optical pressure sensor.
