Mesh suture
A medical device includes a surgical needle attached to an elongated mesh suture. The suture is constructed of macroporous flat wall that facilitates and allows tissue integration into the suture core subsequent to introduction to the body, thereby preventing suture pull-through and improving biocompatibility.
1. A method of re-apposing soft tissue, the method comprising:
piercing a portion of the soft tissue with a surgical needle attached to a first end of an elongate mesh suture;
threading the elongate mesh suture through the portion of soft tissue to make a plurality of stiches,
wherein the elongate mesh suture comprises:
a second end located away from the surgical needle;
a flat wall having a length extending from the first end to the second end, and a cross-sectional rectangular shape with a uniform width and a uniform thickness that is smaller than the width; and
a plurality of pores extending through the flat wall, wherein each of the plurality of pores has a pore diameter of approximately 200 microns to approximately 4 mm, such that the plurality of pores are adapted to accommodate the portion of soft tissue growing through the flat wall, thereby integrating with the elongate mesh suture.
2. The method of claim 1 , wherein the thickness of the flat wall is approximately 0.1 mm to approximately 1 cm.
3. The method of claim 1 , further comprising anchoring the elongate mesh suture in place in the portion of soft tissue after threading the elongate mesh suture through the portion of soft tissue.
4. The method of claim 3 , wherein anchoring the elongate mesh suture in place comprises:
passing the surgical needle through a closed loop anchor at the second end of the elongate mesh suture; and
creating a cinch for anchoring the elongate mesh suture to the portion of soft tissue.
5. A method of re-apposing soft tissue, the method comprising:
piercing a portion of the soft tissue with a surgical needle attached to a first end of an elongate mesh suture;
threading the elongate mesh suture through the portion of soft tissue, wherein the elongate mesh suture comprises:
a second end located away from the surgical needle;
a flat wall having a length extending from the first end to the second end, and a cross-sectional rectangular shape with a uniform width and a uniform thickness that is smaller than the width; and
a plurality of pores extending through the flat wall, wherein each of the plurality of pores has a pore diameter of approximately 200 microns to approximately 4 mm, such that the plurality of pores are adapted to accommodate the portion of soft tissue growing through the flat wall, thereby integrating with the elongate mesh suture; and
anchoring the elongate mesh suture in place in the portion of soft tissue after threading the elongate mesh suture through the portion of soft tissue, wherein anchoring the elongate mesh suture in place comprises:
passing the surgical needle through a closed loop anchor at the second end of the elongate mesh suture; and
creating a cinch for anchoring the elongate mesh suture to the portion of soft tissue.
6. The method of claim 5 , wherein threading the elongate mesh suture through the portion of soft tissue comprises making a plurality of stitches.
7. The method of claim 5 , wherein the thickness of the flat wall is approximately 0.1 mm to approximately 1 cm.
