Abstract:
A system and method for treating a patient using a hybrid imaging system is provided. For example, first imaging data is acquired from a patient using a first imaging device. The patient is transferred on a support to a second imaging device. The support extends between the first imaging device and the second imaging device. Second imaging data is acquired from the patient using the second imaging device. The second imaging device structurally allows for catheter treatment in the patient during acquisition of the second imaging data. The first imaging data and the second imaging data are superimposed or fused. The patient is treated with a catheter as a function of the superimposed or fused data while acquiring the second imaging data.
Abstract:
The invention relates to a catheter device for performing atherectomy, comprising an atherectomy catheter, an IVMRI sensor, position sensors and an image-processing unit which is fashioned for generating combined 2D and/or 3D image recordings based on the data from the sensors.
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:
The invention relates to a catheter device, with a position sensor system, for treatment of a partial or complete vessel blockage under image monitoring, with the catheter device featuring a treatment catheter of a vessel blockage, especially by removal or destruction of plaque and/or expansion of the vessel,, which is embodied as an integrated unit, especially as a combination catheter, with an OCT catheter and an IVUS catheter for image monitoring and with the position sensor system.
Abstract:
The invention relates to a catheter for brachytherapy having a radiation source for generating β or γ rays. So that the catheter can be positioned as precisely as possible it is inventively proposed to provide an NMR device in the area of a free end of the catheter for generating and detecting NMR signals created through magnetic resonance of the atomic nucleus.
Abstract:
To support imaging on a patient, two different image recording methods are to be executed simultaneously. With each image recording method, a supporting fluid, for instance a contrast means or a tracer, can be introduced into the body of the patient. The invention proposes mixing the two supporting fluids with one another in a common solution, prior to releasing it into the patient, i.e. it provides a solution, which consists of a base solution without a medical agent, a first solution as a supporting fluid for a first image recording method and a second partial solution as a supporting fluid for a second image recording method. A plurality of combinations of the first and the second image recording methods are available. If necessary, a third partial solution can be present in the solution in order to simultaneously execute three image recording methods.
Abstract:
An intravenous pacemaker electrode comprises an electrode cable featuring a conductor, a duct and an insulating sleeve as well as an electrode head attached to the distal end of the conductor in order to transmit stimulation pulses, with an OCT catheter being moveable in the duct, and comprising a thread-like guide element as well as an OCT measurement element attached to its distal end.
Abstract:
A pacemaker comprises an implantable pacemaker housing and a pacemaker electrode provided to transmit stimulation impulses, and a detector for a current which can be induced by an external magnetic field and flowing through the pacemaker electrode. A circuit element is provided to interrupt this inducible current.
Abstract:
The invention relates to an angiographic x-ray diagnostic device for rotation angiography with an x-ray emitter which can be moved on a circular path about a patient located on a patient support table, with an image detector unit which can moved on the circular path facing the x-ray emitter, with a digital image system for recording a plurality of projection images by means of rotation angiography, with a device for image processing, by means of which the projection images are reconstructed into a 3D volume image, and with a device for correcting physical effects and/or inadequacies in the recording system such as truncation correction, scatter correction, ring artifact correction, correction of the beam hardening and/or of the low frequency drop for the soft tissue display of projection images and the 3D volume images resulting therefrom.
Abstract:
Device for implementing a cutting balloon intervention by means of a “cutting balloon” catheter, at the distal end of which is disposed an inflatable balloon with axially running blades mounted thereon, and which has IVUS monitoring, whereby the cutting balloon catheter is combined with an IVUS catheter to form an integrated module.
