  • Patent number: 9915523
    Abstract: The invention relates to a system for monitoring a position of a distal end of a tube with respect to a blood vessel of a mammal. The system comprises a source for generating an outgoing beam of electromagnetic radiation having a predefined electromagnetic spectrum. The system furthermore comprises a guideway for guiding the outgoing beam to the distal end, and for guiding an incoming beam of electromagnetic radiation reflected by surroundings of the distal end in response to said outgoing beam to a measurement arrangement, which is arranged for measuring a parameter associated with an electromagnetic spectrum of the incoming beam. The system furthermore comprises a comparator arrangement for comparing said parameter with a reference parameter associated with a reference electromagnetic spectrum representing a predefined location of the distal end inside the mammal.

  • Publication number: 20130035585
    Abstract: The invention relates to a preparing apparatus for preparing an influencing procedure for influencing a subject. The preparing apparatus (1) comprises a subject coil (3) for generating a magnetic resonance image of he subject (7), an instrument guide device (5) for guiding an instrument (6) for influencing the subject (7), a marker (9) being visible in the magnetic resonance image, and an attaching element for attaching the instrument guide device (5) to the subject coil (3) in a known spatial relationship. Since the spatial relationship between the instrument guide device (5) and the subject coil (3) is known, if they are attached to each other, a time consuming registration procedure for registering an influence trajectory, which has been planned based on the magnetic resonance image, and the instrument guide device (5) can be avoided.

  • Publication number: 20110245713
    Abstract: A medical device comprising a probe for measurement temperature data of tissue within a patient's body is proposed. The probe (2) comprises a flexible substrate (3) attached to a medical device core (5), the flexible substrate (3) comprising one or more thermopiles (7) and may furthermore comprise resistors for measuring an absolute temperature and heat sources for locally applying heat. The thermopiles can be processed directly on a flexible polymer carrier or, alternatively, on a silicon substrate and transferred to a flexible carrier (3) enabling both, a highly flexible substrate (3) and very small structural dimensions for the thermopiles (7) and, possibly, the resistors and heat sources. Accordingly, measurement of temperature gradients of tissue being in contact to the medical device may be performed at high resolution allowing reliable detection of temperature anomalies e.g. due to malign tissue.
