Improved fabric with reinforced interlaces

a technology of interlaces and fabric, applied in the field of fabric with reinforced interlaces, can solve the problems of reducing the strength of the catheter, the difficulty of designing two characteristics, and the inability to hold up well under tension, so as to improve the integrity of the second fabric section and reduce the potential for fraying

Benefits of technology

The patent is about a special fabric that has two parts, each with its own pattern of small pores created by the way yarn is interlaced. The first part of the fabric has more interlacings than the second part. This design strengthens the second part of the fabric and reduces the chance of it getting frayed.

Problems solved by technology

These two characteristics are difficult to design as each compromises the other.
Conversely, 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.
In materials and textile components used in minimally invasive applications, another issue is that of unravel or fray of the structure.
It is undesirable to have a loose yarn or have a fabric unraveling.
The loose yarn may cause a blockage of a passageway, for example in applications relating to arterial or venal repair.
In addition, any unravel of a textile component may compromise the structural integrity and ultimately the function of the component or device.

Embodiment Construction

[0035]Referring now to the drawings in which like numerals indicate like parts throughout the several views, FIG. 1A shows a first embodiment 10 of the fabric having first 12 and second 14 sections. The first embodiment 10 is a knit mesh made of a monofilament PET yarn. The first section 12 is made using a first stitch pattern and forming first pores 16. The second section 14 is formed by using a second stitch pattern and forms second pores 18.

[0036]The particular stitch pattern used for the first embodiment 10 is set forth below.

Guide bar 1=(2−1 / 1−2 / 2−1 / 1−0 / 1−2 / 2−1 / 1−2 / 2−3)×17 (2−1 / 1−0 / 1−2 / 2−3)×12

Guide bar 2=(1−2 / 2−1 / 1−2 / 2−3 / 2−1 / 1−2 / 2−1 / 1−0)×17 (1−2 / 2−3 / 2−1 / 1−0)×12

Guide bar 3=(2−1 / 1−0 / 1−2 / 2−3)×46

Guide bar 4=(1−2 / 2−3 / 2−1 / 1−0)×46

[0037]It should be noted that any number of stitch patterns may be used to create a fabric as described herein and that the stitch pattern described above is not intended to limit the scope of the embodiment in any way. As will be appreciated by one skilled i...

Abstract

A fabric having first section and having first pores created by the interlacings of yarn in a first pattern, and having a first average pore size. The fabric also includes a second fabric section having second fabric pores created by the interlacings of yarn in a second pattern, and a second average pore size. The number of first interlacings of yarn is greater than the number of second interlacings of yarn. The first fabric provides strength to the second fabric. The first fabric pattern designed to mitigate any unravel of a second pore yarn in the event it is severed.

Description

FIELD OF THE INVENTION[0001]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.BACKGROUND OF THE INVENTION[0002]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.[0003]In such an application, minimally invasive procedures...
