Definitions
- the invention relates to a stent.
- Such stents or implantable catheters which can be inserted into a body cavity, a vessel or the like, can consist of plastic or of inert metal, such as steel or nickel-titanium alloys.
- Such stents are also referred to in particular as endovascular or endoluminal stents or endoprostheses.
- the stents are used, for example, to expand the ureter in the prostate area for benign prostate hyperplasia (BPH) or also in calcified blood vessels to expand and keep them open.
- BPH benign prostate hyperplasia
- the stents have material areas and spaces between them. This allows the stent to regrow through the wall tissue of the organ kept open.
- Stents can be spiral or in the form of a helically wound spiral; they can consist of woven or knitted wire or plastic material.
- Like stents can have memory properties, such as are given, for example, in certain nickel-titanium alloys (Nitinol).
- a problem with such stents is their limited ability to bend, in particular when they are inserted through narrow organs, such as blood vessels, to the place where they can be expanded. There is a risk that if the stent bends due to action,
- the stents are relatively stiff and inflexible. This applies in particular to stents with a diamond-shaped structure, for example made of nickel-titanium sheet by cutting
- the invention is therefore based on the object of creating a stent which has a high degree of flexural flexibility in the case of forces acting perpendicularly to the axis and, in particular, is not subject to any deformation of its contour, in particular does not undergo any changes in cross section in the case of bends,
- a stent which is characterized in that it has a plurality of meandering tracks arranged one behind the other in the axial direction and extending over its circumference, that between areas of the meandering tracks facing one another in the axial direction and connected by connecting sections in the circumferential direction U at least each two mutually facing, not interconnected areas of each meandering track are arranged.
- An important advantage of the invention is that a high bending capacity is achieved without multi-layer material crossing points, as is the case with knitted fabrics, braids, etc. Because such material crossing points are missing, the stent according to the invention grows better into the tissue. Furthermore, the risk of thrombosis occurring, in particular in the vascular area, is substantially reduced or practically eliminated.
- the connecting sections are arranged offset to one another in the circumferential direction in the axial direction of successive meandering tracks, in particular the connecting binding sections are arranged offset by half a meandering period in the circumferential direction. This maintains or achieves the desired axial strength.
- the meandering tracks can be designed in a variety of ways. For example, preferred configurations provide that the meandering tracks are zigzag-shaped (with tips), that the meandering tracks are sinusoidal, or that the meandering tracks are oval-shaped. Further preferred refinements of the invention provide that mutually facing regions of the meandering tracks are aligned in the axial direction and / or that the width of the connecting areas in the circumferential direction is not greater than the width of the legs of the meandering tracks.
- the stent is preferably self-expanding and consists of a material with memory properties (memory metal); in the low temperature state (far below body temperature) the individual meander legs lie against one another, in the pre-embossed high temperature state (below but closer to body temperature) the stent is expanded radially.
- memory metal memory metal
- Figure 1 shows a preferred embodiment of the stent according to the invention in its
- FIG. 2 shows the stent of FIG. 1 in its high temperature or positioning configuration
- FIG. 3 shows a schematic illustration of a stent which has been cut open and laid flat in the longitudinal direction at its welding points, in order to better illustrate the connection of the zigzag-shaped meander tracks arranged one behind the other in the axial direction;
- FIG. 4 shows a slotted sheet provided for producing a stent according to the invention.
- the stent 1 according to the invention has a basically cylindrical shape, the outer contour of the stent being indicated by dashed lines S in FIG.
- the stent 1 can also have conical or double-conical or frustoconical and other contours. In any case, it has an axis of symmetry A, which determines the axis direction. Furthermore, the circumferential direction is indicated by the arrow U.
- the stent 1 consists of a series of meandering tracks 2, 2a, 2b arranged one behind the other in the axial direction A.
- the meandering tracks 2, 2a, 2b are arranged such that each other facing, adjacent tip regions 3, 3a or 3'a, 3b of meandering tracks 2, 2a, 2b arranged next to one another are aligned in the axial direction.
- Longitudinal axis A itself does not buckle in the central area in such a way that it loses its essentially circular contour in cross section and is flattened in the center in the direction of action of the forces and widened perpendicularly to the direction of action of the forces approximately in the middle of its longitudinal extent, as is the case with conventional stents is the case in which all mutually facing, adjacent tip regions 3, 3a, etc. of meandering turns running side by side are firmly connected by connection regions 4, 4a, etc.
- the connecting areas 4, 4a ... are formed in one piece with the other parts of the stent, in particular the meandering tracks 2, 2a ... and their respective adjacent areas 3, 3a.
- FIG. 3 also shows that the thickness of the connecting areas 4, 4a, 4b, 4c in the circumferential direction is not greater than the thickness of the individual legs of the meandering tracks 2, 2a, ...
- the areas 7, 7 'and 7a, 7a' are welding areas which are connected to one another by welded connections in the closed position of the stent shown in FIG.
- FIG. 4 shows an already slotted sheet from which a stent according to the invention is produced.
- the stent according to the invention consists of a nickel-titanium alloy, such as Nitinol.
- the openings or slots 11, as shown in FIG. 4, are produced in a flat sheet metal in such a way that adjacent slots in the circumferential direction U are each offset by about half their length in the axial direction A. In the central region of each slot 11, this is provided with an extension 12 so that the material delimiting the extension 12 in the circumferential direction is reduced approximately to the width of the material stocks remaining between the slots themselves.
- the sections 13 later, when left standing, form the connecting sections 4, 4a etc., or in their areas when the sections 13 are removed, the free spaces or spaces 5, 5a etc. are created. After the sheet metal has been produced in the form shown in FIG. 4, the sections 13 are initially all left to stand. Only on the left in FIG. 4 was it indicated how later, that is to say after the stent had been produced, as shown in FIGS. 1 and 2, the separations for creating the interspaces 5 were created.
- the sheet shown in FIG. 4 is bent into a cylinder so that the two edges 14, 15 touch.
- the welds are then made at the welding points 7, 7 ', which initially means that a stent is in it Low temperature position according to Figure 1 is created.
- This is followed by heat treatment in order to give the stent thus obtained its memory properties, so that after the temperature has risen above a predetermined ambient temperature which is below the body temperature of the human body, it expands into its high-temperature position in accordance with FIG. 2 can.
- bridges 13 are then removed in the desired manner, so that the connecting regions or webs 4, 4a etc. or free spaces 5, 5 ', 5a etc. are formed, as described above.
- two free spaces 5 of adjacent, mutually facing regions 3, 3a of the meandering windings 2, 2a have been created between two connecting regions or webs 4, 4a which follow one another in the circumferential direction.
- the distances between the connection areas 4 in the circumferential direction can also be chosen larger; As a rule, at least two free areas 5 should be provided between two webs 4 which follow one another in the circumferential direction.
- the invention creates a highly flexible stent that can follow all bends without any impairment.
