摘要： A medical system for minimally-invasive measurement of blood flow in an artery (AT). An interventional device (IVD) with an optical fiber (FB) comprising a plurality of temperature-sensitive optical sensor segments, e.g. Fiber Bragg Gratings, spatially distributed along its longitudinal extension is configured for insertion into an artery (AT). A temperature changer (TC) is arranged in the WD to introduce a local change in temperature (ΔT) of a bolus of blood in the artery, to allow thermal tracking over time with the optical fiber (FB). A measurement unit (MU) with a laser light source (LS) delivers light to the optical fiber (FB) and receives light reflected from the optical fiber (FB) and generates a corresponding time varying output signal. A first algorithm (A1) translates this time varying output signal into a set of temperatures corresponding to temperatures at respective positions along the optical fiber (FB). A second algorithm (A2) calculates a measure of blood flow (BF) at respective positions along the optical fiber (FB) in accordance with a temporal behavior of said set of temperatures. Such system can be used to quickly scan an artery for diagnosing stenotic regions without the need for pullbacks or injection of toxic liquids. A good spatial resolution of the blood flow measurement can be obtained in real-time.

摘要： A rotational position determination apparatus is configured to determine an entry rotational position, which defines a rotational position of an insertion device like a stent at an entry site, such that a navigation of the insertion device from the entry site to a target site along an inner path results in a rotational position of the insertion device at the target site being equal to a desired target rotational position based on a representation of the inner path and the desired target rotational position. If the insertion device is arranged in the determined entry rotational position at the entry site and then navigated to the target site, it is therefore not necessary to rotate the insertion device at the target site.

摘要： The present invention relates to a system (100) for combined ablation and ultrasound imaging of associated tissue (40), which is particularly useful for use in an ablation process. The system comprises an interventional device (20) with an ultrasouond transducer and an ablation unit. During an ablation process, the interventional device (20) can be applied for both ablation and imaging of the tissue (40) subject to the ablation. A controlling unit (CTRL) is further comprised within the system, and arranged to calculate a predictor value based on one or more signals from the ultrasound transducer, where the predictor value relates to a risk of impending tissue damage due to a rapid release of bubble energy. According to a specific embodiment, a primary signal is sent if the predictor value exceeds a threshold value, so that proper measures can be taken.
