摘要： The present invention relates to a catheter for applying energy to an object. The catheter (5) has a longitudinal axis (7) and includes an energy applying unit (30) for applying energy to the object and a sensing unit (20) for sensing the object in a sensing direction (23). The sensing unit(20) is adapted to be rotatable with respect to the catheter (5) such that the angle (Î±) between the sensing direction (23) of the sensing unit (20) and the longitudinal axis (7) of the catheter (5) is adjustable. The sensing unit (20) can be adjusted during the application of energy to the object such that the sensing direction (23) of the sensing unit (20) points to the site to which the energy is applied, regardless of the angle that the catheter tip forms with the surface of the object at that site.

摘要： An ultrasonic assembly suited for attachment to a catheter, e.g. for medical treatment. The ultrasonic assembly includes an adjustable ultrasonic focus mechanism arranged in connection with the ultrasonic transducer to adjust focus of ultrasonic waves generated by the transducer. The ultrasonic focus mechanism includes a fluid focus lens with at least two fluids separated by an interface such that ultrasonic waves are substantially reflected at the interface. At least two electrodes are arranged in connection with the fluid focus lens so as to allow adjustment of the interface shape, e.g. a curvature of the interface, when a voltage is applied to the electrodes. In preferred embodiments the electrodes are arranged so as to allow adjustment of the fluid focus lens in an elevation direction as well as in a radial direction. In simple embodiments with rotational symmetric geometry with the transducer positioned in the centre of the fluid focus lens, ultrasonic waves can be focused in an annular ring. This is e.g. suitable for ablative or coagulative necrotic treatment of human tissue, e.g. for atrial fibrillation treatment. In some embodiments, the assembly has a number of separate individually adjustable fluid focus lens compartments allowing a more detailed control of the ultrasonic focus pattern.

摘要： The present invention relates to a monitoring apparatus (101) for monitoring an ablation procedure. The monitoring apparatus (101) comprises an ultrasound signal providing unit for providing an ultrasound signal that depends on received echo series of an object (4) that is ablated. The monitoring apparatus (101) further comprises an ablation depth determination unit (103) for determining an ablation depth from the provided ultrasound signal. The ablation depth can be determined directly from the ultrasound signal and is an important parameter while performing an ablation procedure. For example, it can be used for determining the progress of ablation within the object (4) and for determining when the ablation has reached a desired progression.

摘要： An adjustable fluid type lens system is provided that allows e.g. ultrasound imaging through the lens during adjustment of the lens. The lens includes a container enclosing two immiscible fluids, e.g. water and oil, being in contact with each other at an interface. Incoming waves are then refracted at this interface. The shape of the interface, and thereby the refraction property, is adjustable by adjusting a voltage applied to the lens. The two fluids are selected such that they together exhibit a mechanical damping which is critical or near critical. A control circuit generates the electric voltage for adjusting the refraction from one value to another, the control circuit being arranged to change the electric voltage such that a rate of voltage change is limited to avoid oscillation of the interface, thereby adjusting refraction of incoming waves at the interface in a continuous manner. This makes it possible to use the lens while it is during adjustment from one refraction value to another, since the interface shape will at all time during the adjustment have a controlled shape. The voltage can be either a continuous voltage or a discrete stepwise (digital) voltage which is just controlled with respect to step size and temporal extension of the steps. The lens system has a number of applications e.g. within the medical field, e.g. for 'on the fly' high speed ultrasound imaging, or for ultrasound ablation applications where ablation can be performed during adjustment of the lens to follow a pre-defined trajectory.

摘要： Touch screen capabilities are added to a color display (10), such as an LCD display with backlighting. Thereto, the wavelength is varied in two color channels along the horizontal (x) and vertical (z) directions. A pen (30) having spectroscopic capabilities incorporated in it for the two relevant colors determines its position by measuring the wavelengths of the two channels.

摘要： The invention relates to a sensor probe (100,110,120,130,140,150) for detecting an environmental state within a bodily lumen. The sensor probe (100,110,120,130,140,150) having an elongated body (9) comprises an optical guide (1) having an outcoupling surface (11),which is part of an end surface (3) of the elongated body (9), facing a reflective surface of an overhanging part (22,42,52,62), a photodetector which detects a property of light which is composed of light (32) in the optical guide (1) that is reflected from the outcoupling surface (11) of the optical guide (1) and of light (33) in the optical guide (1) that is reflected from the overhanging part (22,42,52,62), and a hydrogel material(2) of which a property changes when getting into contact with an environmental material and/or when detecting an environmental change, and which is provided between the end surface (3) of the elongated body (9)and the overhanging part (22,42,52,62). In this way a sensor probe (100,110,120,130,140,150) is provided that, because of its compactness, can be applied inside the bodily lumen for detecting and characterizing parameters that are vital indicators for the state of the human or animal body, and to which the hydrogel material (2) is responsive.
