Definitions
- the invention relates to the field of instruments to be used in minimally invasive procedures, in particular guide wires and catheters.
- Minimally invasive procedures in the human body require guide wires and catheters. These are available in a variety of shapes, sizes, configurations and mechanical properties for X-ray diffraction-controlled processes.
- Metal mesh for catheter reinforcement or wire cores in guidewires include.
- this device excludes, for example, many standard catheters that can be attracted and redirected by the strong magnetic field. Materials that are made from plastics alone meet the requirement of lacking ferromagnetism.
- markers which lead to a local signal cancellation in the MRI image and thus make the instrument easier to find and display.
- materials are suitable which have a different water susceptibility (magnetizability).
- magnetizability To avoid dependencies of this mark from the orientation of an instrument to the magnetic main field, these markers must be applied locally.
- Rare earths which are also used as MRI contrast agents, were used in higher concentrations for this purpose. They have been applied locally as markers as well as catheter fillings to achieve better visibility of instruments on MRI.
- Catheter mount were developed, although security problems caused by it such as heating by the radio frequency field are still solved in any way.
- Such heating occurs when electrical conductors, such as e.g. Metals are exposed to the radio frequency fields over a longer distance in the MR tomograph. If there is a resonance, a summation of the radiated radio energy with the possible effect of substantial heating of the conductor takes place via a standing wave.
- the invention described herein is therefore based on the object to realize MRT-compatible instruments, in particular a catheter and a guide wire, which has no longer contiguous metal parts and thus not subject to the risk of inductive heating, but on the other hand over the entire length along and across to Main magnetization can be displayed in suitable MRI sequences, without the body structures in the environment of the instrument are rendered unrecognizable by artifacts. It is a further object of the present invention to provide MRI-compatible instruments which have no restrictions on their material properties and the associated handling compared with the previously known instruments.
- rod-shaped body consisting of one or more non-metallic filaments and P053-002 4
- non-ferromagnetic matrix material wherein the matrix material encloses the filament and / or glued together, and wherein in the matrix material, a doping of magnetic resonance tomography artifact-producing particles is introduced.
- the combination of the matrix material with the non-metallic filament (s) achieves, in a surprisingly simple manner, metal-like rigidity, flexibility and elasticity properties.
- the filaments forming the rod-shaped body can be produced easily and inexpensively, while being sufficiently stable and can transfer compressive and tensile forces as well as torques.
- a simple and effective possibility is created of displaying the rod-shaped body in the MRI and at the same time ensuring handling in accordance with today's standard.
- the filaments are made of plastic and / or glass fiber.
- Such filaments can be made easily and inexpensively, in long lengths, with different cross-sections and thicknesses.
- glass fiber has the least strains, which is why a very direct force and torque transmission is possible.
- the matrix material may advantageously consist of epoxy resin.
- Epoxy resins are available in a wide range of properties and the equipment required for processing is mature.
- the rods may be continuously doped along their longitudinal axis with magnetic resonance tomographic artifact-producing particles. As a result, the rod is clearly visible on the MRI in its entire length.
- the rod discontinuously along its longitudinal axis in particular in sections, using particles which generate artifacts by magnetic resonance tomography. This is especially true for the tips of the bars, which in some cases should be particularly visible.
- the filaments can be arranged running parallel. This supports a particularly simple processing.
- the filaments can also be intertwined, interwoven, crosslinked, twisted or helically arranged in order to achieve certain desired properties, in particular mechanical properties.
- the mass of a single particle lies in the range of micro to nanograms and, due to the small amount compared to the matrix material, substantially does not influence the outer shape, stability and the torquing properties of the rod.
- Typical preferred sizes of the rods are in the range of a diameter between 0.005 mm and 5 mm, preferably between 0.1 and 1 mm.
- a cylindrical connecting body in particular a guide wire, formed, in such a way that at least one rod is surrounded by a non-ferromagnetic matrix material or more rods bonded to a non-ferromagnetic matrix material and / or be enclosed.
- the cylinder can z. B. special simply consist of rods of the same diameter or - according to another embodiment - of rods of different diameters. In the latter case, second rods of smaller diameter can be arranged in particular around a first rod. P053-002 6
- the individual rods can - as previously filaments - intertwined, interwoven, networked, twisted or helical running arranged.
- the cylinders have rods of different magnetic resonance tomography properties.
- one and the same cylinder eg as a guide wire
- MRT sequences for example for the specific representation of fatty tissue, muscle tissue, etc.
- a tubular connecting body (“catheter”). This consists of at least one rod, which is enclosed by a non-ferromagnetic matrix material and / or more rods glued and / or encloses.
- this consists of several, in its wall on the circumference radially distributed embedded rods. These can be embedded regularly distributed in particular to achieve symmetrical properties regularly.
- the rods forming the catheter may have the same diameter, but in special cases rods of different diameters may also be used.
- the rods may be intertwined, interwoven, cross-linked, twisted or helically extending in the catheter, the rods have different magnetic resonance tomography properties and its outer surface may be hydrophilic coated.
- FIG. 2 shows a cylindrical connecting body (guide wire)
- FIG. 3 shows a tubular connecting body (catheter)
- FIG. 4 shows a cross section through a doped rod
- FIG. 5 shows the tip of a guide wire.
- the rod 1 or rod cutout shown in FIG. 1 consists of an elongated glass fiber filament 2, which is embedded in epoxy resin 3 as matrix material.
- the rod 1 can be produced by conventional methods, in particular by extrusion practically endless. After extrusion, it is optionally cut to suitable lengths for further processing.
- a plurality of filaments 4, 5 can also be arranged in a rod-shaped body 1 instead of a filament.
- these are a relatively thick filament 4 and therefore arranged relatively thin filaments 5. All filaments 4, 5 are bonded to the epoxy resin 3 and enclosed by this.
- a cylindrical connecting body 6 and a portion thereof is shown.
- the extension in the longitudinal direction can be considerably longer and is z. B. several meters with a diameter of z. B. 0.1 mm.
- the cylindrical connecting body 6 is composed of a plurality of bars 1, which are made of a matrix material 7, for. As epoxy, glued and enclosed. This matrix material 7 is, contrary to the matrix material 3, not doped with magnetic resonance imaging particles producing artifacts.
- Visibility of the cylindrical connecting body 6 in the MRI is based solely on the visibility of the embedded rods 1.
- rods 1, 8, 9 of different doping are incorporated, so that depending on the sequence of other rods 1, 8, 9 are visible in the MRI ,
- tubular connecting body 10 (shown again is a portion thereof) may be formed.
- the tubular connecting body 10 is likewise constructed from a jacket material 15 and a plurality of rods 1, 8, 9 of different doping. All rods are regularly distributed on the circumference of the tubular connecting body 10.
- Both the cylindrical connecting body 6 and the tubular connecting body 10 may be provided with a hydrophilic coating, not shown.
- the ends of the cylindrical and tubular connecting bodies 6, 10 may be suitably machined, e.g. B. rounded, polished or provided with an end piece.
- the inner rod 12 may end earlier than the outer rods 13. These are brought together to form a tip 14 (arrangement of the rods 12 and 12) 13 as shown in the cross sections AA and BB, respectively).
