Definitions

  • the invention relates to a method of manufacturing a surgical implant having at least one marking.
  • Surgical implants which include a marking are well known.
  • a marking e.g. at the center of the mesh
  • EP 1 439 796 B discloses an areal implant comprising a meshlike basic structure and a marking in its central area, wherein a straight marking line runs through this marking.
  • US 8 579 922 B describes a kit comprising a surgical mesh and sutures. Each of the corner areas of the mesh is marked by a visually coded patch (e.g., coded by color), which is assigned to a correspondingly coded suture.
  • a visually coded patch e.g., coded by color
  • US 2013/0218125 A discloses an implantable medical device in- eluding a surgical mesh and a perforated film positioned on at least a portion of the mesh.
  • the film may include graduated markings .
  • US 2013/0317286 A describes a surgical implant comprising a bioabsorbable incision reinforcement element, a long-term mesh and a bioabsorbable coating disposed on the mesh.
  • the incision reinforcement element can be provided with an alignment marker including crossed marking lines.
  • US 2005/0288691 A discloses a hernia patch comprising a sheet formed of one or more layers of a thin flexible material suit- able to promote or prevent tissue adherence and a grid formed of intersecting lines . The lines are imprinted on the sheet or made from stitches .
  • Another surgical implant suitable to hernia repair is known from DE 10 2013 004 486 A.
  • This implant comprises a basic structure including a mesh, which is folded back at the periphery of the implant to form pockets, wherein overlapping parts of adjacent pockets are connected to each other.
  • An ab- sorbable marking pattern is cut from a poly-p-dioxanone film and placed on top of the mesh and an anti-adhesive film (tissue separating layer) . After performing a melt-fusing step (lamination by heat) , the poly-p-dioxanone material connects the mesh and the anti-adhesive film and provides marking lines.
  • Common processes for providing and attaching markers to a flexible mesh implant are sewing with a defined and limited stitch length, cut-plotting of a marker film and fixation of the cut film onto the mesh by lamination, printing a marker onto the mesh, or inlaying of colored threads into the textile structure during a knitting process .
  • the object of the invention is to find a method of manufacturing a surgical implant, in which a flexible areal basic structure can be provided with markings in a convenient, versatile and largely unrestricted way. This object is achieved by the method of manufacturing a surgical implant as defined in claim 1.
  • Advantageous versions of the invention follow from the dependent claims. Claim 16 relates to a surgical implant manufactured by this method.
  • a surgical implant is manufactured.
  • the method comprises several steps.
  • a flexible areal basic structure is provided, which has a first face and a second face.
  • At least one linear marking thread is placed, in a floating manner, onto one of the faces of the basic structure.
  • the marking thread is mechanically fixed (e.g. by stitching) to the basic structure at a first location and at a second location, wherein the first location and the second location are spaced from each other.
  • the lin- ear marking thread is thermally fixed to the basic structure, in an area between the first location and the second location, by a melt-fusing process.
  • the method may include at least one further manufacturing step, e.g. before the basic structure is provided, after the marking thread has been fixed, or in between the above steps. Examples for such steps are the application of a barrier film or cutting and folding steps to bring the implant into its final shape .
  • the term "areal" means that the basic structure is a generally flat structure (e.g. of surgical-mesh material), which may be curved into the third dimension, however. Moreover, the basic structure may be folded (preferably but not necessarily after applying the marking threads), e.g., to form pockets.
  • the implant may consist of the basic structure and the marking threads only, but additional components (e.g. a film attached to the basic structure, etc.) are conceivable as well.
  • a blank of the basic structure may have any shape.
  • a basic structure constituted of more than one part is also possible. In the method according to the invention, the at least one marking thread is placed onto the basic structure in a floating manner.
  • the marking thread is applied with floating fibers, which initially are not attached or interwo- ven with the basic structure in between the first location and the second location.
  • the marking threads are fixed to the basic structure, preferably by a sewing process with sewing stitches (e.g. in the edge area of the basic structure).
  • the individual marking threads are designated as linear because they are not used for preparing an extended areal assembly.
  • the individual marking threads are placed in a straight manner, in between the respective first and second locations, but without exerting any significant tension onto the basic structure.
  • the step of placing the marking threads is highly efficient. There is no waste of material like in a process where a marking pattern is cut out from a film.
  • the floated marking threads are melted (or at least transferred into a rather soft state) and converted to a filmlike structure so that they may be laminated to the basic structure. For example, they may be bond to, a mesh structure by enclosing the mesh filaments, thus preventing delamination .
  • the filaments of the marking threads may form a smooth and even surface, which may enhance visibility due to a largely directed reflection of light.
  • the method according to the invention enables the application of absorbable marking threads onto flexible mesh implants without changing the material characteristics of the remaining implant after the absorption of all absorbable components .
  • the direction of the marking threads does not depend on any- knitting direction of a mesh-like basic structure. That means, marking thread lines can be applied at any angles with respect to a reference direction, e.g. as orthogonal markers.
  • the method allows the use of sensitive materials for the basic structure, e.g. of monofilaments which are sensitive to sharp needle tips or of basic material which is sensitive to distortion by the tension of a seam, because the marking threads are placed in a floating manner and any stitching may be restricted, e.g., to peripheral or edge areas .
  • the first location and the second location of the at least one linear marking thread can be positioned in a pe- ripheral region of the basic structure. It is even possible that parts of the basic structure containing the first location and/or the second location are removed from the implant after thermally fixing the linear marking thread to the basic structure. In that case, the implant does not include any moreareas which might have been damaged by mechanically fixing the linear marking thread (s) during manufacture.
  • a linear marking thread or bundle of linear marking threads (forming one mark- ing line) is placed on the first face of the basic structure and, opposite thereto, another linear marking thread or bundle of linear marking threads (forming one marking line) is placed on the second face of the basic structure, wherein both linear marking threads or bundles of linear marking threads are stitched together in respective end areas thereof.
  • a process step can be conveniently performed on appropriate state-of-the-art textile machines.
  • the linear marking thread or bundle of linear marking threads on the first face is securely connected to the linear marking thread or bundle of linear marking threads on the second face, during the melt-fusing step, wherein a mesh-like basic structure may be sandwiched in between.
  • a bundle of linear marking threads is a plurality (i.e. more than one) of linear marking threads generally arranged in parallel to each other.
  • a plurality of linear marking threads or bundles of linear marking threads may be provided, on at least one face of the basic structure, to form a pattern of marking lines.
  • Such a pattern can significantly aid a surgeon in correctly positioning and aligning the surgical implant, depending on its shape and the kind of surgery.
  • At least one marking line may comprise a bundle of linear marking threads including more threads than another marking line.
  • the individual threads are generally aligned in parallel to each other without being intertwined.
  • an axis running through the center of the implant can be marked by a marking line containing more individual threads than other marking lines, wherein it is assumed that the individual threads have the same diameter. In this way, the mid- line of the implant is highlighted, which facilitates an easy recognition of the orientation of the implant.
  • a more pronounced marking line can also be achieved by a thread having a greater diameter (in which case the individual filaments of the thread are generally intertwined, e.g. twisted or braided) .
  • a combination of monofilament threads and twisted multifilament threads can be applied in order to achieve a variety of marker types. Every single marking line in a pattern may be adjustable in thickness by the number of applied threads. It is also possible to place linear marking threads on top of each other in order to increase the height of the marker into the third dimension so that a marking line can become palpable. Different colors of the marking lines in a pattern provide another way for an easy distinction between individual marking lines.
  • the marking lines in a pattern can be used for marking the midline of the implant or an axis perpendicular thereto. It is also possible, however, to mark the periphery or certain areas of the implant.
  • the method according to the invention is very versatile and permits the provision of many different patterns of marking lines, including well distinguishable marking lines, largely independent of the size of the implant .
  • the pattern of marking lines may include marking lines along the periphery of the implant and/or marking lines connecting opposite corners of the implant and crossing each oth- er in a center area of the implant.
  • the basic structure e.g., a surgical mesh
  • the markings described therein form a somewhat different pattern, however. Moreover, they are shaped from a film structure connected to the basic structure, or they are embroidered or sewn on the basic structure, which does not involve the advantages of the present invention.
  • the pattern of marking lines comprises a prominent midline and less prominent grid markers .
  • the grid markers run about the periphery of the implant, and they connect opposite corners of the implant, i.e. those corners not connected by the midline.
  • one grid marker line runs through the center of the implant, but crosses the midline at a right angle.
  • each of the grid marker lines includes two pairs of parallel linear marking threads, wherein each pair is composed of one linear marking thread ("needle thread") running on the first face of the basic structure and one linear marking thread (“bobbin thread”) running on the second face of the basic structure.
  • the midline contains eight pairs of parallel linear marking threads so that it is more pronounced than the grid markers.
  • Each pair of parallel threads is positioned across the basic structure using a floated needle and bobbin thread.
  • the ends of the threads of each pair are stitched together.
  • the at least one marking thread may be provided as a monofilament or as a multifilament, e.g. as a twisted multifilament.
  • the marking thread is absorbable and has a melting temperature lower than that of at least one constituent of the basic structure, which generally facili- tates the melt-fusing process.
  • a preferred material is poly-p- dioxanone, in particular dyed (e.g. violet) poly-p-dioxanone . Any combinations of materials and properties for different marking threads are possible as well.
  • the basic structure may comprise a surgical mesh, e.g. a surgical mesh as used in hernia repair.
  • the basic structure is macro-porous, e.g. having a pore size of at least 1 mm. It may be a light-weight construction having an areal weight of less than 50 g/m 2 , but it could also be heavier.
  • the basic structure can comprise, e.g., a warp-knit, a weft-knit, a crochet-knit and/or a woven fabric, but also a perforated film.
  • the filaments may be bio-absorbable or nonabsorbable, and the filaments can comprise mono-filaments and/or multi- filaments (including multi- filaments made from different materials) . Tape yarns and/or drawn film tapes are conceivable as well.
  • the basic structure may comprise absorbable material, non- absorbable material or a combination of absorbable material and non-absorbable material.
  • a mesh-like basic structure may be warp-knitted from threads which are twisted from absorbable and from non-absorbable filaments.
  • Advantageous materials for the basic structure include, e.g., polypropylene, fluorinated polyolefines , blends of polyvinylidene fluoride and copolymers of vinylidene fluoride and hexa- fluoropropene (e.g. PronovaTM, Poly (Hexafluoropropylene-VDF) material of Ethicon) , which are all non-absorbable.
