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 (&#x394;T) 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.

A medical method and system include a medical imaging system configured to generate images of an interventional procedure. An overlay generator is configured to generate an overlay image on the images of the interventional procedure. An interventional device tracking system is configured to track a three-dimensional position, orientation and shape of the interventional device during the procedure, wherein the overlay image is dynamically updated in response to deformations caused to an organ of interest by the interventional device during the procedure.

An apparatus, system and method for determining a position of an instrument () includes a sheath () configured to fit within an instrument channel of a medical scope. An optical fiber () is disposed within the sheath and a plurality of sensors () is integrated in optical fiber. The sensors are configured to measure deflections and bending in the optical fiber. A fixing mechanism () is sized to fit within the instrument channel in a first state and fixes the sheath within the instrument channel in a second state such that the fixing mechanism anchors the sheath and the optical fiber so that the deflections and bending in the optical fiber are employed with a pre-procedural volumetric image to determine a position of the instrument.

Apparatus, system and method for imaging and treatment using optical position sensing

The present invention relates to an apparatusand, a method and a computer program for determining a parameter indicative of a tissue type of an associated tissue. In particular, the invention relates to an apparatuscomprising a spectrometer, which spectrometer comprises a light sourceand a detectorarranged to measure an optical spectrum. This enables determination of a first parameter being indicative of a bile concentration. As the inventors of the present invention have made the insight that bile concentration may serve as a discriminative feature for different tissue types, the apparatus is arranged to determine a second parameter indicative of a tissue type based on a concentration of bile. According to a specific embodiment, the apparatus further comprises an interventional device

Apparatus for optical analysis of an associated tissue

An integrated optical shape sensing system and method include an arrangement structure () configured to receive a fiber port or connector. A platform () is configured to provide a distance relationship with the arrangement structure such that the fiber port or connector is trackable to provide a location reference. The platform secures a patient in proximity to the arrangement structure. An optical shape sensing enabled interventional instrument () has a first optical fiber cable connectable to the fiber port or connector. An optical interrogation module () is configured to collect optical feedback from the instrument and has a second optical fiber cable connectable to the fiber port or connector such that a known reference position is provided for accurate shape reconstruction.

Integration of fiber optic shape sensing within an interventional environment

An optical probe and an optical imaging system include an optical guide, and an actuator having driving coils and a magnet. By supplying a driving current through the driving a magnetic flux is generated which causes a displacement of the distal end of the optical guide. A position measuring device includes a position measuring coil used for monitoring the position of the optical guide, where displacement of the guide distal end causes change in the relative positions of the measuring and driving coils. A power supply supplies a high frequency AC current through the driving coils which causes, an induced voltage in the position measuring coil and thus generates a magnetic coupling between the measuring and driving coils. This induced voltage change is indicative for the position of the distal end.
