Definitions

  • the invention relates to an expandable insert with the features of the preamble of claim 1.
  • the known inserts have three tubular sections or segments that are made of a material that is compatible with an implant.
  • the three tubular segments are each connected to one another via bridge webs which are intended to allow the segments to be tilted or interleaved.
  • the individual segments are formed by cutting out rectangular sections from the jacket of the tubular segments.
  • adjacent cutouts are offset from one another in the circumferential direction.
  • the rectangular cutouts have long sides parallel to the axis and narrow sides running in the circumferential direction.
  • the front narrow sides are not connected to each other, so that the front side of the tubular segment looks crenellated.
  • the interconnected segments are aligned coaxially to one another in the unused state of the insert and are connected by bridges between the narrow faces at the front.
  • straight, parallel bridge webs run obliquely from one end face of a segment in the direction of the narrow side adjacent to the opposite narrow side in the circumferential direction.
  • Each narrow side of a segment is connected to a narrow side of the adjacent section, so that the inclined bridge webs give the insert a twisted appearance.
  • the rings with a shorter strand length can absorb compression forces well, while the rings with a longer strand length cover the spaces that arise between the rings of the first group relatively evenly.
  • the rings of the second group also allow flexibility in use for bending loads to the extent required.
  • the strand length of the second group is 1.2 to 2.0 times as long as the strand length of the first group, in particular 1.3 to 1.5 times as large, because there is a good relationship between these conditions Expandability and length reduction when expanding results.
  • An increased flexibility with respect to bending stresses results if the strand length of the second group is 1.7 to 1.9 times as long as the strand length of the first group.
  • the meandering strands of the second group have longitudinal sections which, in the unexpanded state, run parallel to the central axis of the base body.
  • the meander-shaped strands of the first group have peripheral portions which extend in the unexpanded state in the circumferential direction of the body '.
  • FIG. 1 shows the developed lateral surface of a cylindrical, tubular stent in the unexpanded state.
  • the jacket section 1 is shown in a plan view, the view showing the cylindrical, tubular base body being cut open along an axially parallel cutting line 2 and shown flatly spread out.
  • the outer surface is formed by a number of meandering strands 3a, b and 4a, b.
  • the material strands 3a and 3b are curved in a meandering or undulating manner in the circumferential direction of the insert, with almost semicircular arc sections 5 and straight longitudinal sections 6 running parallel to the axis alternating.
  • the strand length of the encircling material strand 3a or 3b is approximately 14.5 mm, which in the embodiment shown results in a diameter of 1.8 mm in the unexpanded state.
  • the meandering strand 3a or 3b can be periodic recurring shape are considered, each period comprising two longitudinal sections 6 and two arc sections 5. In this exemplary embodiment, three periodic regions are thus arranged in the circumferential direction.
  • the material strands 4a and 4b are also arranged circumferentially in a meandering fashion.
  • arc sections 7 and longitudinal sections 8 alternate, the longitudinal sections 8 running approximately parallel to the longitudinal sections 6 of the material strands 3a and 3b in the unexpanded state of the insert.
  • the material strands 4a, 4b also have a periodicity, the number of periods in this exemplary embodiment being twice as large as the number of periods of the material strands 3a, 3b. In the figure 1, the embodiment has six periodic sections.
  • the length of the material strands 4a, 4b is approximately 11 mm in the present exemplary embodiment, which also leads to a diameter of 1.8 mm in the present design.
  • the material strands 3a and 3b prevail approximately centrally in the respective longitudinal section 6 of the material strand 3a, 3b.
  • the material strands 4a, 4b penetrate the material strands 3a, 3b approximately at right angles.
  • the expandable insert according to the invention is cut as a one-piece element on a tube with an outside diameter of 1.8 mm.
  • implantable stainless steel is used as the material, but also other implantable materials.
  • the material thickness in the radial direction is essentially constant over the entire range of use.
  • FIG. 2 shows an insert according to FIG. 1 in the second, expanded state.
  • the diameter of the Use in the expanded state is 3.5 mm in this embodiment.
  • the resulting deformation by the application of a force acting radially from the inside leads to the material strands 4a and 4b being fully stretched, that is to say in practice forming a circular ring of 11 mm in circumference.
  • the longer material strands 3a and 3b are deformed into wavy, almost sinusoidal material strands.
  • the material strands 4a and 4b which are annular in the expanded state, oppose a uniform radial force exerting a great structural resistance, which reliably prevents the insert from collapsing in the treating blood vessel.
  • a lower material thickness can be used with the same resistance (recoil) compared to the known inserts. In both cases, the risk of a renewed narrowing of the cross-section of the treating blood vessel, also called re-stenosis, is lower than in the known applications.
  • the inserts according to the invention are inserted into the blood vessels to be treated with a balloon catheter.
  • the balloon catheter is expanded by injecting a fluid, whereupon the inserts expand permanently in the radial direction due to plastic deformation.
  • the insert After removing the balloon catheter, the insert remains in the blood vessel and we are surrounded by the intima within a short time.

Abstract

L'invention concerne un insert pouvant se déployer, à utiliser comme extenseur dans des vaisseaux sanguins. Ledit insert peut être déformé plastiquement, par application d'une force radiale dirigée de l'intérieur vers l'extérieur, de façon à passer d'un état non déployé à un état déployé, cela grâce à au moins une section de corps de base tubulaire, sensiblement cylindrique, dont la surface latérale est constituée d'une pluralité d'anneaux définissant un cercle, en forme de méandres. Ces anneaux forment chaque fois un tronçon de matériau d'une seule pièce, d'une longueur définie. L'insert présenté est particulièrement rigide par rapport aux forces radiales s'exerçant extérieurement, grâce à l'utilisation d'un premier groupe d'anneaux dont la longueur de tronçon correspond sensiblement au périmètre de l'insert à l'état déployé, et d'un deuxième groupe d'anneaux, dont la longueur de tronçon est plus grande que le périmètre de l'insert à l'état déployé.
