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 IVD 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 system for monitoring changes during therapy includes a first probing segment (112) having an optical fiber sensor disposed therein. The first segment is percutaneously inserted in or near a target area and providing a local reference for one or more treatment devices.

摘要： An image-guided prosthetic valve deployment system employs a prosthetic valve (80), a catheter (70) and a delivery tracking system (90). The catheter (70) has an elongated body with a proximal tip (71a) and a distal tip (71b), and the elongated body includes a delivery section (72) adjacent the distal tip (71b) for deploying the prosthetic valve (80) relative to a heart valve (21) within an anatomical region (20). The delivery section (72) includes a delivery segment (73) for sensing a shape and an orientation of the delivery section (72) within the anatomical region (20) relative to a reference point (74). The delivery tracking system (90) tracks a position and an orientation of the prosthetic valve (80) relative to the heart valve (21) as a function of a sensed shape and a sensed orientation of the delivery section (72) within the anatomical region (20) relative to the reference point (74) by the delivery segment (73).
