Abstract
A medical device includes a surgical needle attached to a hollow tubular suture. The suture is constructed of macroporous hollow tubular 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.
Claims (28)
1. A method of re-apposing soft tissue, the method comprising:
piercing a portion of soft tissue with a surgical needle attached to a first end of an elongated mesh suture; and
threading the elongated mesh suture though the soft tissue to make at least one stitch that closes an opening in the soft tissue,
wherein the elongated mesh suture further comprises a porous flat strip having a plurality of pores extending through the flat strip, at least some of the plurality of pores having a pore size that is greater than or equal to approximately 200 microns such that the at least some of the plurality of pores are adapted to facilitate tissue integration through the porous flat strip when introduced into a body.
2. The method of claim 1 , wherein a second end of the elongated mesh suture opposite the first end is attached to an anchor comprising a planar sheet having a dimension that is larger than a width of the elongated mesh suture.
3. The method of claim 1 , wherein the porous flat strip extends along the entirety of the elongated mesh suture between the first end and a second end opposite the first end.
4. The method of claim 1 , further comprising anchoring the elongated mesh suture in place by passing the surgical needle through a closed loop anchor at a second end of the elongated mesh suture opposite the first end and creating a cinch for anchoring the elongated mesh suture to the soft tissue,
wherein the second end of the elongated mesh suture opposite the first end is a free end not connected to a needle, and
wherein the porous flat strip extends along the entirety of the elongated mesh suture between the first and second ends.
5. The method of claim 1 , wherein a second end of the elongated mesh suture opposite the first end is a free end not connected to a needle, and
wherein the second end of the elongated mesh suture opposite the first end is attached to an anchor comprising a planar sheet having a dimension that is larger than a width of the elongated mesh suture, and
wherein the porous flat strip extends along the entirety of the elongated mesh suture between the first and second ends.
6. The method of claim 1 , further comprising anchoring the elongated mesh suture in place by passing the surgical needle through a closed loop anchor at a second end of the elongated mesh suture opposite the first end and creating a cinch for anchoring the elongated mesh suture to the soft tissue,
wherein threading the elongated mesh suture through the soft tissue comprises making a plurality of stitches that close an opening in the soft tissue,
wherein the second end of the elongated mesh suture opposite the first end is a free end not connected to a needle, and
wherein the porous flat strip extends along the entirety of the elongated mesh suture between the first and second ends.
7. The method of claim 1 , wherein the threading the elongated mesh suture through the soft tissue comprises making a plurality of stitches that close the opening in the soft tissue.
8. The method of claim 7 , further comprising anchoring the elongated mesh suture in place by passing the surgical needle through a closed loop anchor at a second end of the elongated mesh suture opposite the first end and creating a cinch for anchoring the elongated mesh suture to the soft tissue.
9. The method of claim 7 , wherein a second end of the elongated mesh suture opposite the first end is a free end not connected to a needle.
10. The method of claim 7 , wherein a second end of the elongated mesh suture opposite the first end is attached to an anchor comprising a planar sheet having a dimension that is larger than a width of the elongated mesh suture.
11. The method of claim 1 , further comprising anchoring the elongated mesh suture in place by passing the surgical needle through a closed loop anchor at a second end of the elongated mesh suture opposite the first end and creating a cinch for anchoring the elongated mesh suture to the soft tissue.
12. The method of claim 1 , wherein a second end of the elongated mesh suture opposite the first end is a free end not connected to a needle.
13. The method of claim 11 or 12 , wherein the porous flat strip extends along the entirety of the elongated mesh suture between the first and second ends.
14. A method of re-apposing soft tissue, the method comprising:
attaching a surgical needle to a first end of a suture;
attaching a first end of an elongated flat mesh strip to a second end of the suture, the elongated flat mesh strip having a plurality of pores, at least some of the plurality of pores having a pore size that is greater than or equal to approximately 200 microns such that the at least some of the plurality of pores are adapted to facilitate tissue integration through the elongated flat mesh strip when introduced into a body;
piercing a portion of soft tissue with the surgical needle; and
threading the elongated flat mesh strip though the soft tissue, wherein threading the elongated flat mesh strip through the soft tissue comprises making a plurality of stitches that close an opening in the soft tissue.
