Definitions

  • the embodiments described herein are directed to a fabric having reinforced interlaces and at least two different average pore sizes created by at least two different stitch or weave patterns.
  • An interface is created where the spacing of the nodal points change.
  • the reinforced interlaces help to strengthen the larger pores at the interface and reduce the potential for fray or unravel.
  • Medical textiles are used in a multitude of applications both for external application as well as internal and implantable applications.
  • Today due to the advancement in technology and the rising cost of health care, more medical and surgical procedures are done using minimally invasive techniques. This includes the use of endoscopes, and the like, to view, explore and perform surgical procedures on a patient within the parameters of an endoscope or other minimally invasive instrument.
  • minimally invasive procedures require the instruments and other components of the process to be capable of significant compression. This is to enable the components to travel through a catheter to the site of the procedure. Further the components must be designed to unroll or otherwise decompress so as to function as designed once they arrive at the predetermined location.
  • a capturing device may be used to enclose a tissue sample which will be analyzed by the surgeon once it is retrieved from the body.
  • the materials must be extremely light weight and relatively thin or capable of being compacted into a thin profile for travel via a catheter.
  • the components must be strong enough to function as designed so that their slightness in weight does not detract from their structural integrity. These two characteristics are difficult to design as each compromises the other.
  • a fabric that is designed to be strong is typically heavier in weight and bulk.
  • a fabric that is light weight and capable of assuming a slight profile for travel via a catheter is typically not strong and does not hold up well under tension.
  • fray refers to the ability of the fabric in the areas of more concentrated interlacings or nodal points to absorb strain from the areas of less concentrated interlacings and nodal points and reduce the potential for the stitches to loosen or come undone.
  • the embodiments described herein relate to a fabric having a first fabric section having first fabric pores created by the first interlacings of yarn in a first pattern, and having a first average pore size.
  • the fabric further includes a second fabric section having second fabric pores created by the second interlacings of yarn in a second pattern, and a second average pore size.
  • the number of first interlacings of yarn exceeds the number of second interlacings of yarn. The first interlacings enhance the integrity of the second fabric section and reduce the potential for fray.
  • the fabric of the embodiments described herein has a configuration where the first fabric section may surround the second fabric section.
  • the fabric of the embodiments described herein may have a difference in average pore size between the first average pore size and the second average pore size, where the difference is at least 100%.
  • the fabric of the embodiments described herein may have a difference in weight between the first and second fabric sections, where the difference is at least 50%.
  • the fabric of the embodiments described herein may have a difference in thickness between the first and second fabrics, where the difference may be at least 10%.
  • the fabric of the embodiments described herein may have a difference in the burst strength between the first and second fabric sections, where the difference is at least 50%.
  • the fabric of the embodiments described herein may have a difference in the number of interlacings, where the number first interlacings is at least 50% more than the number of second interlacings.
  • the fabric of the embodiments described herein may have a difference in the percentage of open area, where the open area of the first fabric section may be about at least 7% less than the percentage of open area of the second section.
  • the fabric of the embodiments described herein may be knit or woven.
  • the embodiments further provide for a method of creating a reinforced mesh fabric, by creating a first fabric section having first fabric pores created by the first interlacings of yarn in a first pattern, and having a first average pore size, and creating a second fabric section having second fabric pores created by the second interlacings of yarn in a second pattern, and a second average pore size, wherein the number of first interlacings of yarn is greater than the number of second interlacings of yarn.

  • FIG. 2B shows a representative second pore 18 formed by the interlacing of knit second pillars 22 .
  • the first section 12 surrounds the second section 14 , as shown by interface line 15 .
  • the first section 12 encapsulates the second section 14 by using reinforcing interlaces which work in opposition to one another to support the second section 14 by providing additional points within the section where the yarns interlace.
  • the first section 12 of additional interlaces provides enhanced structural support to the second pores 18 when stressed.
  • the additional interlaces of the first section 12 mitigate or prevent fray or unravel by absorbing any cut yarn or end from further unravel by absorbing the tension into a point of interlacing or node, and discouraging further travel of the end of frayed yarn.
  • the first section 12 has a greater density than the second section 14 because the first pores 16 are smaller and the number of interlacings is greater over a fixed area.
  • the number of interlacings in the first section 12 is approximately 26 per inch, while the number of interlacings in the second section is approximately 14 per inch.
  • the first section 12 also has a greater weight than the second section 14 .
  • Table C below provides elongation data of the first 12 and second 14 sections of the first embodiment in pounds 10 over elongation. As can be seen in the graph, the first section maintains its integrity under strain for a longer period of time given the same rate, than the second section.
  • a second embodiment 24 provides for a different stitch pattern as shown in FIG. 3 .
  • the second embodiment 24 has a first section 26 having first pores 27 and a second section 28 having second pores 29 .

  • FIG. 5 is a diagrammatic representation of the guide bar movement of the second embodiment 24 .
  • FIG. 6 is an enlarged view of the second embodiment 24 illustrating in greater detail the first section 26 and the second section 28 .
  • the first section 26 has a smaller pore size and a greater number of interlaces or nodes than the second section 28 .
  • the second section 28 has fewer interlaces than the first section 26 and has a larger pore size.
  • an area having a greater interlaces or nodal points may also act as a visual or tactile aid at the boundary between the areas where the number of nodes change.
  • this interface helps a worker to more efficiently or effectively attach a fabric piece onto a frame or device. This interface may aid the worker in more effectively installing the mesh piece onto a frame or other object which will result in a higher quality product.
  • nodal points as a visual and/or tactile aid may be incorporated into all facets of manufacturing where fabric having fewer nodal points or fewer interlaces is manipulated onto a frame or other device.
  • the reinforcement area where the nodal points are greater helps to provide visual guidance to the person threading the fabric onto the wire or tube.
  • the higher interlacing area provides visual guidance to the worker so as to ensure that the pores are threaded properly and thus the product quality is greater.
  • Variation on the number of interlaces in a given fabric at a particular location may also help to provide a visual or tactile aid to ensure that the less dense area is oriented properly.
  • the surgeon may be able to look at the fabric or feel the fabric and determine by the pattern whether the mesh is oriented properly. When the mesh is oriented properly, the success rate of the procedure increases and thus patient quality of life is enhanced.
  • the fabrics described herein may apply to both woven and knitted fabrics. With respect to knit fabrics, different stitch patterns may be used as applications require. The stitch pattern and density impact the knit mesh qualities of strength, pore size, stability and elongation. Where such properties need to be altered, the stitch pattern and/or density are altered
  • FIGS. 6 and 7 show third and fourth embodiments in a woven construct.
  • FIG. 6 discloses a third embodiment 30 having a first section 32 having a tighter weave and more interlacings and nodal points.
  • the second section 34 of the third embodiment 30 has a more open weave with fewer interlaces and nodal points.
  • the first section 32 of the third embodiment 30 has a 1,1 weave, and the second section 34 has a 2,2 weave.
  • FIG. 6 also shows the weave pattern of both first 32 and second 34 sections.
  • FIG. 7 is another example of a woven embodiment and provides a view of the fourth embodiment having a first section 38 having a tighter weave surrounding a second section 40 of a more open weave.
  • the interfaces between the first 38 and second 40 sections is circular but may be designed as needed or desired to support need and function of the fabric.
  • the weave pattern of both the first 38 and second 40 sections is also provided.
  • the first section 38 of the fourth embodiment 36 has a 1,1 weave and the second section 40 has a 4,4 weave.
  • a further application of the present embodiments is for the creation of fabric scaffolding for cell in-growth. It is anticipated that by configuring fabrics of varied pore size, cell in-growth can be encouraged. As a result, a fabric scaffold may be designed to encourage growth of particular cells by size and thus location on or in the fabric scaffold.
  • the knit patterns shown herein are linear in shape, having a straight length and width.
  • a resulting piece was desired to have a diamond shape
  • that shape may be achieved either by cutting that shape into a sheet of fabric, or by knitting the piece to the desired shape.
  • the knit pattern would need to include tapered sections to create the diamond shape.
  • any number of linear and curved shapes may be achieved and that the diamond is an example and in no way intended to limit the scope of the embodiments described herein.
  • Applicant further notes that there is at least one alternative method for creating the embodiments disclosed herein.
  • an alternative method is to apply tension to an area of fewer nodal points and subsequently heat treat the fabric. The area under tension will maintain its density while the remaining fabric will shrink or retract, thus creating a higher number of nodal points or interlacings. This method can be applied to the variety of embodiments described above.
  • a yarn or a pore is intended to mean a single yarn or a single pore, or more than one yarn or pore.
  • uses within the specification of terms such as “upper,” “lower,” “vertical,” “horizontal,” and the like are words of convenience used to describe the structure and function of the parts of the embodiments herein relative to each other and are not meant in any way to be construed as limiting terms.
