Abstract: A cryocatheter for introduction into a body vessel or into an organ, with a catheter inner surrounded by a catheter sheath, and with a catheter tip arranged at its distal end, with a feed line for an expansion or cooling agent arranged in the catheter sheath or the catheter inner, and with a balloon, arranged close to the catheter tip, which can be expanded and contracted again by means of the expansion and cooling agent, is to be constructed in such a way that by simple manipulation it can be positioned at a precise target position in the body vessel and, in addition, it minimizes the burden on the patient from invasive interventions. For this purpose, in accordance with the invention an image capture device, with at least one imaging sensor for mapping the region of the vessel around the balloon, is positioned in the region of the catheter tip.
Abstract: In a method and an apparatus for implementing a gastric artery chemical embolization (GACE) catheterization procedure, an x-ray imaging system obtains a first current image data set of the patient prior to implementing the GACE procedure, and a second current image data set that shows the blood vessels that supply the fundus of the subject. The first and second current image data sets are fused to form a first fusion image data set. A second fusion image data set is then formed by fusion of the first fusion image data set with a catheter-position-indicating data set, obtained during the GACE procedure. The second fusion image data set is displayed during the GACE procedure or control data for a lightweight robot, used to operate and guide the catheter, can be derived from the second fusion image data set.
Abstract: The invention relates to a device for taking high energy images, in particular, X-ray images, comprising an input image by means of which data for a medical auxiliary may be inputted into the device. Said medical auxiliaries are preferably stents or contrast agents which can be introduced into the body of a patient. The display unit of the device can thus be correspondingly set for the applied auxiliary.
Abstract: A method for guiding nanoparticles to a target location by a magnetic gradient field and/or holding them at the target location is proposed. The magnetic gradient field is generated by a magnet system with at least one magnet. A focus of the magnet system is registered with an X-ray device. At least one three-dimensional image dataset showing the target location is captured by the X-ray device. The position of the target location is determined manually and/or automatically in the image dataset or in an image dataset determined therefrom and is positioned automatically based on the registration of the focus so that the focus coincides with the position of the target location.

The gantry is arranged on a supporting structure so as to be movable in space. The supporting structure is a ceiling-mounted stand having at least two degrees of freedom of movement. The gantry has at least two radiation sources disposed offset by an angle on the rotor arrangement and associated with each of which is at least one radiation detector.

The device provided for carrying out the method comprises a medical instrument that is to be introduced into a moving body region of the patient, a robot which has a plurality of degrees of freedom of movement and on which the medical instrument can be disposed for guiding, and means for recording the movement of the body region, wherein the medical instrument can be introduced into the body region of the patient by means of the robot taking into account the movement of the body region and guided in the direction of a target tissue in the body of the patient.
Abstract: In a method and an apparatus for conducting minimally-invasive procedures involving heart valves at least one multi-access articulated x-ray imaging robot is employed that allows a radiation detector carried by the robot to be moved in arbitrary paths, such as in circle, an ellipse, or along a spiral, around a patient in order to generate multiple projection exposures of the relevant region of the patient during the procedure. An image processor reconstructs a 3D image from the projection exposures substantially in real time during the procedure, and the 3D image is displayed to operating personnel during the procedure.

Abstract: The present invention relates to a system for performing and monitoring minimally invasive interventions with an x-ray unit, in which at least one x-ray source and one x-ray detector can traverse a circular track through an angle range, an ECG recording unit, an imaging catheter, a mapping unit with a mapping catheter and an ablation unit with an ablation catheter. The system comprises a control and evaluation unit with interfaces for the units and catheters, which enable an exchange of data with the control and evaluation unit. The control and evaluation unit is designed for processing measurement or image data which it receives from the catheters and units, and for controlling the catheters and units for the capture of the measurement or image data. The workflow from the examination through to the therapy, particularly with regard to the treatment of tachycardial arrhythmias, is covered completely and continuously by the proposed system.
Abstract: An apparatus with two pairs of X-ray systems is provided. Each of the X-ray systems has an X-ray source and an X-ray detector. The X-ray detectors differ from each other in their spatial resolution. The X-ray detector with the low spatial resolution makes it possible to record X-ray images in a faster temporal sequence than the other. The doctor carrying out the treatment thus has the option of deciding between the availability of a high spatial resolution and the recording of images in a rapid temporal sequence.
